To the naked eye, there isn’t much difference between consumer and IoT/M2M SIMs. The SIM in your mobile phone looks pretty much like the SIM in an IoT device, but there are critical differences. Your phone SIM is a commercial UICC plug-in, while an IoT device that is enabled to remotely manage subscriptions and has space for a removeable SIM is using an eUICC plug-in SIM. So, while they may look the same, the capabilities of eUICC SIMs are revolutionary for the IoT market- and the most secure eUICC formfactor on the IoT market today is the embedded SIM.

Let’s look at the different layers of an eUICC SIM and how those layers need to match in order for the SIM to work.

How are the layers linked together?

The hardware Operating System (OS) and electrical profile work like a minicomputer, with the different layers needing to be compatible for the SIM to function correctly. Not just any OS with work with any hardware, though, and it’s the hardware and OS compatability that decides if a SIM can support eUICC functionality.

eUICC functionality allows the SIM to remotely download, switch, and enable a different profile.

This means there is no need to physically change the SIM – you can switch between different profiles in the same MNO, or from one MNO profile to a different MNO profile.

The Operating System

In addition to matching with the hardware, the OS supports important features on the SIM. If there is a PIN active on the SIM, the PIN handling is in the OS, as are authentication, access, and management of files and data, along with loading and deleting applications. Encryption/decryption and tamper proof functions are also handled in the OS.

One eUICC profile, many MNO profiles

An eUICC SIM has one eUICC profile but can store multiple MNO profiles, although only one MNO profile will be enabled at a time. So, what are these profiles?

The Tele2 (MNO) profile and eUICC profile are personalizations of the SIM. They contain network keys and subscription identifiers (IMSI, ICCID, authentications keys.) The Tele2 profile can either be personalized when the SIM is produced in the factory, or it can be downloaded later through SM-DP (Data Preparation)/SM-SR (Secure Routing).

Profiles can also contain applets, which are small programs on the SIM dedicated to fulfilling a particular task.

The task could be implementing the business logic to change a connectivity profile based on rules, such as when one network is not available and you want the next best available one.

If the SIM has a local applet, this is stored in the Tele2/MNO profile. If it’s a global profile it will be in the eUICC profile. To provide interoperability applets are typically developed in JAVA.

Today Tele2 IoT has an applet that clears forbidden networks, and in 2024 local management and management of 5G stand-alone on eUICC will be launched.

What is unique in an eUICC SIM?

Every eUICC SIM has an EID (eUICC identifier) which is the administrational key in the hardware layer. If there is an MNO profile change the SIM will have a different ICCID and IMSI, but once the eUICC SIM is produced its EID is never changed.

The EID contains 32 digits compared to the ICCID’s 20. There is a shortened version of the EID printed on both the embedded and plug in eUICC chip. The EID is provisioned in the SM-SR, which is also responsible for managing the status of profiles on the eUICC.

Hardware and formfactors

When using a SIM that has eUICC capabilities it is important that the hardware is robust and long lasting. ETSI has a classification of the different environmental properties in which the SIM is graded.

On a SIM technical sheet, the environmental performance can be represented in a string, together with which version of ETSI specification was used. The string of letters can then be looked up to understand what the SIM can withstand.

For example, the environmental property temperature has the grades TS, TA, TB, and TC. The Premium industrial SIM is graded as TB in its ETSI, string while a commercial SIM is graded TS. The eUICC Premium Industrial SIM can be stored and operational in the temperature range of -40 °C to + 105 °C ,while the UICC commercial SIM can only be used in the temperature range of -25 °C to + 85 °C

As mentioned before there are two types of SIM cards: plug-in formfactors (2FF, 3FF, 4FF) that are removable, and embedded formfactors that are soldered into the device. The most popular embedded SIM on the IoT market is the MFF2 (M2M Form Factor).

As the abbreviation applies the MFF2 SIM is designed for M2M/IoT use cases and is delivered on what looks like an old film reel. It is one of the most secure chips due to being soldered into the device and the device can be designed in a way that makes it more robust in general. An embedded SIM is also a greener alternative to plug-in SIMs, with less plastic and metal per SIM.

It’s not always crystal clear how your particular IoT Journey will look. The steps you take along the way may follow a clear path, or you may take unexpected turns as your business grows and evolves. One thing is clear, though: with the right support and services you’ll get the most from your IoT journey, no matter where it takes you.

When you started your IoT journey you probably had a business case that would best be realized by connecting things. Everyone’s experience is different and sometimes, when devices are first deployed, controlling that deployment is not at the top of the to-do list;  maybe the deployment wasn’t so big that it needed many changes so contacting the help desk for any changes was all you really needed. It was relatively simple, and you were just happy to have coverage.

Now you had more control and started optimizing your costs, and maybe even started to see the possibilities of new revenue streams, due the data you had. Time passed and new requirements made you reconsider your connectivity provider or your choice of connectivity technology, meaning you now had not one or two but three (or even more) legacy deployments.  Your choices now have you on three parallel IoT journeys, but that’s what customers wanted, right? Complexity was increasing, overview and control was hard, not to mention all those issues with data layers. The need to unify and simplify them became apparent and you began using products that helped you do that.

Once your connectivity was unified you continued to grow, again deploying more devices and getting more data and it’s at this point that you saw that you needed to get deeper into business analytics and get better insights into how your devices were performing – after all, big data is a hygiene factor these days. Online GUI is great, but you want those insights and data delivered straight into your own systems. API and streaming are the way forward, and you now need smarter connectivity.

quotes icon

IoT is not a race – but you do need to stay one step ahead of the competition. Developing the right solution with the right tools at the right time is the key.

Because you were determined to get the most from your IoT deployment you made it smarter and in turn, your business continued to grow. You might have started with 500 devices but now have 50 000 or even 100 000+ and are deploying in places you wouldn’t have dreamed of a few years ago – but which come with their own regulatory challenges. At this point you have a completely different set of requirements from both a global connectivity perspective and a quality perspective. You require low latency and probably attractive pricing beyond the retail offer.

Fragmented technologies, unpredictable connectivity costs, and regulatory difficulties might be just a few of the challenges you’re facing.  And the off-the-shelf connectivity everyone is offering is no longer enough for deployments of this nature. You need something bespoke that is tailored to your needs, but you don’t want to be heavily investing in building up an IoT/Telco company inhouse to deliver all of this – you want it delivered as-a-Service.

You’re always going to need your global SIMs with roaming agreements, you’re still going to need analytics, and you will always need to unify because who knows what technology lies around the corner? Your choices now should future proof your IoT solution, no matter what comes tomorrow .

The good news is that if you’ve made considered choices along the way you have already implemented technologies, products, and services that build upon one another, so as you reach unicorn status it’s really just a matter of adding that final layer that will make everything you’ve built work in harmony, like a well-oiled machine.

Building from the bottom up and adding layers where and when needed will take a lot of pain out of your IoT journey. With Tele2 IoT it doesn’t matter where you are in your journey – our solutions are built like legos stacked on top of one another: they fit with whatever you are building, whether that’s getting your deployment off the ground, unifying an already-complex solution, or giving you the tools you need to manage your global deployment in one consolidated access technology-agnostic platform.

It’s only been a decade or so since IoT grew some roots and really started to change the world as we knew it. Early adopters were bold enough to take a calculated risk and go where no company had gone before. In doing so, they were able to not just enhance their business and hopefully open new markets, they were also able to help shape the road ahead, simply by dint of being there first.

The stakes are much higher for early adopters, though, and it means navigating pitfalls along the way. When it comes to IoT those early days pitfalls included fragmented technologies, organizational issues, lack of user experience and knowledge, and security concerns. Those who began their IoT Journey a bit further down the road or who are now about to start their IoT journey can learn a lot from those who braved the wild west early days of IoT, because despite the challenges, IoT has brought an enormous amount of value to companies that have implemented it.

• Identify use cases and business benefits

As the IoT hype wanes, focusing on developing use cases with clear business benefits is more critical than ever. Not only will this identify benefits such as cost savings, revenue generation, happy customers, and optimized processes, it will also help you avoid lame arguments like ‘everyone’s doing it’ while convincing company decision-makers to make IoT a priority

• Implement cross-functional collaboration

It’s important that your IT department partners with other functions and units; this can be an opportunity to assess skill gaps while also spreading new capabilities across your organization. It’s also important to understand that it’s not just the CTO who needs to understand your IoT deployment – C-level involvement across the board is important right from the start.

• Have a data plan

Data is the superpower of IoT but the more IoT you do the more data you’re going to have to handle. In order to keep things under control, understand where data is coming from, what you want from it, and how you’re going to analyze it.

• Make security and privacy a priority

When data is flowing the potential for it to be breached is always there, but you can minimize the risk by taking security seriously and working with your provider to ensure the secure solution that meets your particular needs.

In the age of the information economy, data is the most critical asset of any enterprise. Between 2015 and 2018 Big Data adoption in enterprises soared from 17% to 59% – but the amount of unstructured data generated can mean companies becoming overwhelmed and not knowing what to do with all of this potentially valuable information.

We say ‘potentially valuable’ because it is only valuable if it is effectively analyzed and then used to support your company’s ambitions.  According to Gartner, fewer than 50% of documented corporate strategies mention data and analytics as fundamental components for delivering enterprise value. But, Gartner also predicts that number will rise to 90% by 2022 , as more and more companies understand the critical role of data as an asset and analytics as a competency in taking faster and more reliable decisions.

Knowing what to do with the data generated by your IoT solution can mean the difference between moving ahead of the competition or falling behind.

Why data matters

Having a clear data and analytics strategy is crucial to getting value from collected data. In order for companies to not get lost in the process – simply collecting data without knowing what to do with it – they first need to ask:

  • What do we want to achieve with data collection?
  • Do we have the resources we need to do this?
  • How will we turn our data into insights?
  • How will we govern the data in our company?

Where to Begin

Understanding and identifying what data you require is the first step in creating a successful IoT deployment. Depending on your needs, once you have that raw data you need to unlock its value, which means managing it, and then combining it with other data, such as product, sales, or customer data, as well as environmental data.

You then need to ask yourself how your business is performing. By analyzing your data, you can quantitively describe one or more functions of your business. The insights you get can be a key input for you, as a company, to improve processes and decisions.  Using data in the decision-making process means you’re taking better and more efficient decisions because your decisions are fact-based – and no longer based on assumptions, instinct, or previous ways of working. You improve your business based on the knowledge you’ve unlocked from your data.

Do More with Your Data

Data isn’t just about fact description, though – it’s also about predictions. Predictive analytics are set to be the most common IoT data analytics use case, reflecting a gradual shift in emphasis from basic data preparation to actionable insights.

According to a recent report from GSMA Intelligence, while the majority of current IoT deployments use IoT data analytics, it is mostly used for data management and discover to perform basic statistical analysis. As companies expand their IoT deployments, though, the potential for data analytics lies in extracting targeted business benefits.

Take a company that needs real time data, such as a healthcare solution. A patient wearing a connected medical bracelet or wristband, for example, will generate data that allows you to start looking for patterns of usage and behavior.  You can then begin making predictions and then take actions based on that data, whether it’s an alarm citing an emergency or addressing health patterns that need to or should be corrected.

Even more interestingly, particularly if we’re talking about healthcare, is data gathered from a wide swathe of people – this can be used for research purposes, which in turn could lead to medical advances.

Another example could be fleet management. Real time monitoring tells you things like location and travel routes, but data will also help you improve your processes, which means not just getting data on things like fuel consumptions, safety, and number of stops, but also to optimize things like employee schedules and vehicle maintenance. When it comes to public transportation companies, data is used to optimize route planning and keep the public informed in real time. From a longer-term perspective, a lot of planning and processes can be improved.

The long-term predictive possibilities are nearly endless: agriculture data allows you to see patterns in weather and climate over a number of years, while a utilities company can look at peak and valley usage.

Deliver Value

The data generated by IoT has enormous potential to transform your business and relying on the knowledge built from data is crucial to being on top of the market’s changing demands. With analytics impacting everything from product development to identification of unmet demand and supply gaps, workflows and process are being transformed. This could be anything from operations management systems to hospitality companies using what they’ve learned about customers behaviors to improve sales and marketing operations.

IoT data has to be looked at in relation to other sources of data, and each data set has to be analyzed not just on its own but as part of the larger picture. By taking a deep look into everything in their current architecture and then defining how data will be integrated into their existing setup, companies can do anything from enhance pricing and user experience to optimized lead generation process, improve customer efficiency, and limit production downtime.

At the end of the day IoT is all about the data and what you can do with it to enhance your business. Having a clear strategy will help you get most from it.

The Internet of Things (IoT) has been a buzz word ever since it first entered the Gartner “Hype Cycle” in 2011. By the time it first peaked in 2014 experts were predicting 50 billion connected devices by 2020, with investment topping $20 trillion. People thought everything from lamp posts to clothing to our bodies would be connected.

But whenever there is hype people tend to jump in feet first, instead of first dipping their toe in to test the temperature. It’s no different with IoT – five years on from it first peaking in the Hype Cycle the smoke has cleared and a different picture has emerged. The expected number of connected devices is now closer to 20 billion, with investment likely to be in the billions, rather than trillions.

So, what changed?

The US-based research and advisory firm Gartner first published its annual Hype Cycle in 1995. According to Gartner, new technology goes through five cycles: Innovation Trigger, Peak of Inflated Expectations, Trough of Disillusionment, Slope of Enlightenment, and Plateau of Productivity.

When IoT made its 2011 debut in the Hype Cycle it was part of the Innovation Trigger, before moving into the Peak of Inflated Expectations in 2014. Two years later, Gartner created a separate Hype Cycle for IoT, a move many speculated was based on the idea that while some IoT uses were maturing, others still had a way to go – and a separate hype cycle would better reflect the fragmentation.

When it comes to B2B, it’s clear that IoT is maturing. Streamlined processes, cost savings, possible new revenue streams – these are all proven benefits. Many companies see it as an essential part of their business strategy, but instead of going full steam ahead, their IoT solutions are based on a business case and they often started with a pilot, rather than with full implementation right away.

Even as companies gain increasing understanding of IoT and how to best utilize it, challenges remain.

Despite IoT being a key strategic priority for companies, far too many solutions either fail or are not wholly successful.  Penetration is high, but utilization is low. Integration challenges, cost and duration of implementation, lack of skills and knowledge, fragmented markets, security questions – these are all reasons why an IoT solution can struggle.

It has taken far longer for companies to develop a firm understanding of the complexity of IoT, and even more importantly, many companies implement a solution without fully understanding or identifying which problem IoT will address, and how they will extract value from their IoT solution.

Additionally, the complexity of implementation varies from industry to industry. It’s easy to see and derive value when you slap a tracker on a car: you know where it is, you know when it needs maintenance, and you can measure everything from fuel consumption to road conditions.

On the other hand, connecting an airport is in many ways even more complex than connecting a city. There are systems for shops, airport tax, services to airline companies, support for the elderly or infirm, parking, WiFi… the list goes on and on. On top of that there are operational requirements, such as knowing where the baggage is.

quotes icon

If we look at car trackers vs complex airport ecosystems it’s plain to see that there is no one-size-fits-all IoT solution – and the more that this is understood the quicker IoT will mature.

As IoT has evolved the smart IoT provider has learned that focusing on core capabilities, with the understanding that no single company can deliver the entire IoT solution on its own, puts them in a better position to serve their customers. Acting as a partner to customers by helping them identify where IoT will deliver real value and then drawing upon an external partner ecosystem to being together the right ingredients is a big part of IoT being where it is today. IoT providers are now thinking long term; the solution that works today may not be the one the customer needs tomorrow. Both businesses and technology evolve, and IoT is now acting proactively, prepared and ready for what is heading our way.

Another area where IoT has matured is understanding how to manage data and offering solutions to customers.  Realistically, it doesn’t matter how much data is flowing – if you don’t have a clear understanding of what you want from it and then a way to extract value you’re not getting much of anything from your IoT solution.

At the end of the day, IoT hype is well-deserved. It is the kind of technology that can truly transform a business, from an operational standpoint as well as a business development one. As the rate of maturity increases, companies will no longer implement solutions without enough foresight or knowledge because providers will be on hand to guide them through the process and act as a real partner.

For more than 25 years the SIM (Subscriber Identity Module) card has been fundamental in the development of mobile telecommunications. First introduced in 1991 SIMs began life about the size of a credit card and were designed to store information used to identify and authenticate users.

SIMs were also used to connect devices to 2G GSM (Global System of Mobile Communications).  SIM advancements have developed in close parallel with advances in cellular network evolution – but not all SIM cards were created equal.

SIMs & IoT

The rise of IoT meant the development of a different kind of SIM. While an IoT SIM acts similarly to a standard SIM, it does a very different job, offering features and functionalities that you won’t find on the SIM you have in your phone.

One main difference is the subscription type; among other things, an IoT subscription allows you to monitor data usage and SIM activity, you can activate and deactivate it, and you are able lock it to a device. You can also share data across all devices and have multi-operator coverage.

Another difference is the robustnes, since SIMs are often found in harsh environmental conditions. While standard SIMs only possess a 25°C to 85°C temperature range, an industrial IoT SIM can operate to temperatures as low as -40°C and as high as 105°C. Industrial IoT SIMs also enjoy a much longer life span than standard SIMS, due to their 17-year data retention capability, increased storage capacity, and as many as 16 million read-write cycles. Industrial IoT SIMs can come in any form factor, depending on the size of the device and the purpose it serves.

quotes icon

As SIMs continue to evolve, particularly in the IoT arena, the impact on business will be tremendous.

New SIM technology

With everything from smart homes to autonomous cars and Industry 4.0, the integration of IoT technology into both our everyday lives and a company’s core business is inevitable. But first we need to turn on the eSIM, which in many ways holds the key to the connected world.

Unlike with smart phones, where you can connect to WiFi and download an eSIM profile, with IoT there is not a person to connect and download the eSIM locally, so it has to be done remotely.

And there-in lies the beauty of the eSIM: everything can be managed remotely, including switching your connectivity provider, which offers tremendous savings when it comes to logistics and field support. And having a solution based on the global GSMA standard means you ensure both compatibility and future proofing.

Speaking of the future, what is next in store for IoT when it comes to SIM cards? Will they even be with us in five or ten years’ time – or will we have already moved on?

Predicting the future

In the future, we could see all devices connected through secure connections enabled by SIM technology, and it will be possible to change a subscription model remotely for optimal connectivity. eSIMs introduce a truly digital distribution of connectivity which enables new business models to evolve.

We’ll also see a higher degree of embedded SIMs, meaning SIMs that are built-in, where essentially there is no plug-in SIM at all in the connectivity-enabled devices.  These will play a big role in how quickly and seamlessly tracking devices connect.

An embedded SIM is a hardware-centric SIM integrated into the chipset. These SIMs will, among other things, simplify supply chains, enable smaller devices, improve power consumption, reduce costs, and maintain high security levels.

Chipsets, modules, and other hardware components will be produced with eSIMs, with provisioning connectivity profiles, which means the end product can connect directly.  The connectivity provider profile can be remotely changed if and when needed, and we thus move from a linear to a circular SIM lifecycle.

Because an eSIM can store multiple connectivity profiles we will also see more functionality being developed on top of the SIM – so-called SIM applets. SIM applets are small programs inside your SIM dedicated to fulfilling a particular task. This could be implementing the business logic to change a connectivity profile based on rules, such as when one network is not available.  This would provide redundancy for high-availability solutions, such as alarms.  Another business logic could be to automatically change a profile based on which which country the IoT device is trying to connect in.

SIM technology will continue to evolve to support new business logic and value creation – and SIM functionality will remain critical to your IoT solution in securely identifying and authenticating every device.

When you begin your IoT journey you might want to try to keep it simple while still covering all your bases: you want to connect devices, get a good overview, have good service quality and security – and you also want to optimize and control costs. That’s a lot of things to consider and the solution taken is often the easiest: signing with a single supplier with a single technology.

What companies often don’t include in the decision-making mix is this: as your IoT needs become more complex the solution you start with may not be the solution you need as your business grows.

So, while it may sound like planning the divorce before you even get married, when you meet an IoT supplier there is one question you should ask before any other:

How will you help me leave you?

Prepare for the supplier to be startled by you demanding the ability to switch (eUICC) before you’ve even signed on the dotted line – but make sure you listen carefully to their answer on how this will actually be done. If they don’t have an exit plan for you or are going to make it difficult or expensive for you to leave at some point you’re going to run into one very big problem: Lock In Effects.

Ways You Can Get Stuck

• You might be moving into markets you didn’t initially expect to be growing in – maybe another region, another country, or even another continent and need roaming services

• You may only need 500kB of data per month when you start but as you mature and customer demands rise, you might need 10 Mb per month

• Customers’ demands have changed and you need to involve different types of connectivity, such as cellular for some and another solution for customers with locations where cellular doesn’t work

• When you started you only needed your device to connect once an hour or once a day. Growth means it is essential for it to connect every minute in order for your business to not just continue to grow but to succeed

Choosing your supplier based on not just your initial IoT needs but the needs you might have in two, five, or even ten years can mean the difference between failure and success. You can’t predict the future but you know your business and your goals better than anyone else and should plan accordingly.

Moving to a new supplier can be – and often is – prohibitively expensive. Here’s why: just say you have 50 thousand SIM cards deployed and you need to both deploy more and also use several different types of technology across several regions.  Unfortunately, your supplier doesn’t offer different types of technology, nor does it have roaming connectivity.  Additionally, it wants to keep charging you the same rate you’ve always been charged.

Because you chose a supplier who lacks the flexibility you now need and you didn’t have a long-term strategy in place you’re not in a great position to renegotiate the terms of your contract. If you want to simply switch suppliers you may find that you’ll have to go out into the field and manually switch out SIMs, which is both cost prohibitive and labor intensive. The result is that you’ll probably end up multi-sourcing your connectivity in order to meet the demands of your customers, making your IoT solution all that much more complex. Why? Multi-sourcing means multiple platforms to manage, and multiple suppliers to overview for cost control and quality of service.

Living in an ideal world

In an ideal world from the moment you received your trial kit you were thinking long-term strategy and making decisions based on not just your needs of today, but also the needs you’ll be addressing in the future. Developing both a short-term and long-term strategy and involving key people in your organization, such as the CEO or the CIO, right from the start is key. A company-wide perspective, along with having the right people involved at ground level will help you successfully facilitate your company’s IoT transformation, as well as fully reap its benefits.

We don’t live in an ideal world, though. You have deadlines, you need to move fast, and IoT takes time to think through. The good news is that if you have fallen into a pitfall there are actions you can take.

How can a prospective IoT business differentiate the qualities of one Telecom operator’s connectivity offer from another? Which connectivity provider gives best all-round value when it comes to reliable machine to machine connectivity, IoT expert service, and pricing? Here are top 5 tips that we recommend you to take a look at in order to optimize your data consumption and find the best IoT connectivity partner. 

The communication between things provides significant value for most industries today, such as lowering service costs with remote access, efficient energy utilization through real-time monitoring and creating new revenue streams by selling differentiated services.

We use connected machines to perform variety of different tasks to achieve this business value. It can be using car sensors that enable pay-as-you-drive auto insurance. The ability to monitor equipment remotely or GPS tracking that monitors vehicles/containers location and activity. The use cases are endless.

As connectivity is a crucial part of all M2M/IoT solutions and one of the potential cost drivers, it is important to make sure you choose a Telecom operator that can help you optimize your data consumption. Below you find five tips on what to look for.

1. Understanding the units you’re using

Does the telecom operator understand diversity in M2M/IoT devices? Is the connectivity service provider experienced in dealing with HW units and how they are being used in field? In example, some tracking units uses Binary for data format that uses much less data than ASCII. If you have units that support both then make sure you set the unit to use binary as the data usage will be lower.

2. The configuration of your device

Depending on your needs, you should configure the best optimal setting on your device. Because actual configuration of your device will affect the amount of data being used. For example in GPS tracking devices, the way you want to have the tracking interval/polling and heartbeat are very important. If you want to set tracking time down to seconds, then the device will push a lot of data. Using heartbeat and/or sleep mode (if supported) would save cost.

3. Rounding effect (the handshake cost)

If you configure the device to be always ON (learn how long a data session can be with your telecom operator and CDR creation maximum timeout) instead of starting a data session, sending few bites and closing the session down, will save you up to 15% cost. This means you can lower your costs by aligning according to the rounding policy of your telecom operator for around 5-15% depending on how often you send data.

4. Reliability of the cellular connectivity

Static devices sending non-critical data may only require single network SIMs if the coverage in given location is good (do not forget that coverage also depends on the traffic at base station in a given time). But if the device is roaming/mobile, operates from areas with shaky signal coverage, or involved in sending business critical data, a single network SIM (or a SIM with roaming steering to the “cheapest” network partner) presents risks of connectivity failure. Multi-network SIMs go a long way in addressing this risk by automatically switching connection between networks to retain best signal connectivity. So, ask if you are getting full roaming without network steering and access to the best signal in a given location?

5. Automation to prevent overage charges

Most of the connectivity service providers also have some sort of SIM management platform. Check if your platform can be pro-active and take action if something un-expected happens. Inability to do anything beyond simple email alerts on potential issues is a possible extra cost and/or customer dissatisfaction for you. Real-time ability to de-activate rogue devices or push a notification into existing IT systems via APIs means devices with problems can be fixed before they become customer support calls to you.

All in all; you should look for the competence level of your telecom operator before signing an M2M/IoT deal with them. Most of the network and connectivity issues can often be resolved online or over the phone. But sometimes the M2M devices themselves malfunction or may experience network signaling issues. Check if your Telecom operator has testing skills that can work with you to physically examine the M2M device to ascertain the most likely cause of the problem? Will the service provider be able to help get you back up and running quickly if anything goes wrong?
