What is an IoT SIM card?

IoT SIM cards are small, programmable chips that are used to provide a secure and reliable connection to the internet for various devices and machines. These SIM cards are designed to be used in devices that require remote monitoring, control, and data transmission capabilities. The main advantage of IoT SIM cards is that they allow devices to be connected to the internet and communicate with other devices or systems, regardless of their physical location. This makes them an essential component of IoT-enabled systems and devices.

One of the key benefits of IoT SIM cards is their versatility and flexibility. They can be used in a wide range of devices, including smart homes, security systems, energy management systems, industrial machines, and vehicles. For example, in the case of smart homes, IoT SIM cards can be used to connect various home appliances and devices, such as smart locks, security cameras, and smart thermostats, to the internet. This enables homeowners to remotely monitor and control their home appliances and devices from anywhere, at any time.

Another key benefit of IoT SIM cards is their ability to provide a secure and reliable connection to the internet. IoT devices and systems generate and transmit large amounts of data, and it is critical that this data be transmitted securely and without interruption. IoT SIM cards provide a secure connection to the internet by encrypting the data transmitted between the device and the network. Additionally, they can be programmed to automatically switch between different mobile networks to ensure that the connection remains stable and secure.

IoT SIM cards are also highly cost-effective, as they do not require a separate modem or router to connect to the internet. This reduces the overall cost of the device or system, making it more accessible to a wider range of users. Furthermore, many IoT SIM cards come with flexible data plans that allow users to pay only for the data they actually use, reducing the overall cost of ownership.

What industries use IoT SIM Cards?

The list is vast! We see new and creative uses for IoT SIM cards everyday in conversations with our clients. The only limitation to the use of IoT SIM cards is the imagination of the engineer and/or entrepreneur who are developing solutions to problems. Below is a list of just 5 industries we see the most use of IoT SIM cards:

  1. Healthcare: IoT SIM cards are used in a range of medical devices, such as remote patient monitoring systems, wearable devices, and telemedicine systems. These devices use the secure and reliable connection provided by IoT SIM cards to transmit patient data to healthcare providers, enabling them to monitor patient health and well-being from anywhere.
  2. Agriculture: We wrote a case study about the growth of IoT in Agtech (pun intended). IoT SIM cards are used in smart agriculture systems to monitor soil moisture levels, crop yields, and weather conditions. This enables farmers to make informed decisions about crop management and to optimize their operations for maximum efficiency.
  3. Energy Management: IoT SIM cards are used in smart energy management systems to monitor and control energy usage in buildings and industrial facilities. This enables building owners and managers to reduce energy costs and to ensure that their facilities are operating efficiently.
  4. Transportation: We also wrote an article and a case study about the use of IoT SIM cards in the transportation industry.  IoT SIM cards are used in vehicles to provide real-time monitoring and control of the vehicle’s systems, including engine performance, fuel consumption, and location. This enables fleet managers to optimize their operations, reduce fuel costs, and improve safety.
  5. Retail: IoT SIM cards are used in retail systems to monitor and control the temperature and humidity of refrigerated storage units. This ensures that perishable goods are stored at the correct temperature, reducing waste and improving food safety.


IoT SIM cards are an essential component of IoT-enabled systems and devices. They provide a secure and reliable connection to the internet, enabling devices and systems to communicate with each other and with remote monitoring systems. IoT SIM cards are versatile, flexible, and cost-effective, making them a popular choice for a wide range of industries, including healthcare, agriculture, energy management, transportation, and retail.

Vehicle Telematics Client Goes Global: Case Study

Connected Vehicle with Connected Lines of Data
Vehicle telematics connect many systems in a vehicle


Vehicle Telematics has been a continually growing field for many years and has become a very mature category for connectivity. In this article we discuss a Vehicle Telematics client who has been with us for over 7 years. They operated in North America and decided to expand their reach beyond North America. With over 20,000 connected vehicles on our platform, going worldwide will increase the addressable market by over 10X (based on their estimates). They not only track GPS location and speed of vehicles for their customers, but also have solutions that read and report data points like, hard acceleration and deceleration, engine diagnostics, cargo temperature, and moisture levels, accessory activation (think plow up/plow down for snow plowing equipment), and many, many more data points on which they report.

The Challenge

It’s one thing to do business in North America. When you want to expand your business to other continents and many other countries, all of your operational challenges grow exponentially. IoT SIM Card connectivity is one of these operational obstacles. There are several ways to overcome this problem though. Some organizations choose to get native IoT SIMs in each country . As you grow globally, this strategy is less and less efficient when adding more and more countries to your marketing plan. You must:

    • Source the IoT SIM cards from a local provider. Sourcing from new providers can take you back through an RFP process and hoping upon hope that you choose wisely;
    • Configure your devices correctly. Each new connectivity provider has its own settings (APN, etc.) which you will have to maintain new SKU’s for each country and had the devices setup either at the factory when ordering new shipments, or locally by your Operations team in country;
    • Learn new platforms. Many M2M SIM Card companies have their own software and when you start to use several providers, now you have to learn new platforms (and remember all those new passwords!!), setup new API’s, and remember which provider is for which country…nightmare!!
    • Deal with currency exchange rates. Yes, this is a consideration! Working in new countries means dealing with new currencies, and the frequency by which currencies vary can keep your Finance team up at night.

Go Global for Vehicle Telematics Connectivity

Another strategy to overcome the struggle with global expansion for Vehicle Telematics connectivity is to choose a provider with a global footprint. Global  IoT SIM card connectivity providers are not all the same, though, and there can be pitfalls when choosing the right one for you. We talked about the considerations for choosing the right provider in a previous post.  One of the things we talked about was coverage. Having service available in the countries you are going to market your Vehicle Telematics solution is obviously critical, but having multiple networks available is also very important for redundancy.  But how does a global IoT SIM card provider solve the issues mentioned above?:

    1. Sourcing SIM cards. Having a true global IoT SIM card provider eliminates having to search for a provider in each country you open for new marketing. You can rely on the same team you are used to working with and there is no need to go through a new purchasing process
    2. Configuring your devices. Your Vehicle Telematics devices can be setup the same way for any country you want the device in which it operates. Global IoT SIM card providers have a single APN setting and this eliminates the problem of multiple SKUs for each country to which you are sending devices.
    3. Learning new platforms. This goes without saying. Keeping the same provider means you only have one platform to learn. All of the API’s are also the same, so integration to your portal is simple.
    4. Currency fluctuations. Having one provider means that you are working with a single currency. The fluctuations in currencies aren’t going to have an impact.

The Solution 

Our customer looked at the different options outlined above. They decided the wise choice was to use OneSimCard IoT as their provider for their global expansion. This was a simple decision though. They know us and our platform very well, and have integrated their portal with ours through APIs. They understood we were able to provide service in all of the countries to which they were looking to expand, while keeping service costs low. There were several countries where the cost of service was significantly higher. For these countries we created a parent/child account structure. With this structure they could isolate these higher cost countries from the lower cost countries.

We also worked with the client to simplify logistics. We are sending the IoT SIM cards directly to their factory. By doing this, the factory can test the units before they leave the facility. We provide them with free data for this testing. Sending the SIM cards to a single facility had another benefit because they saved on shipping costs.

New API & New IoT Sim Card

New API Command Available for SIM Card Reset

We continue to listen to our IoT clients and their requests for improvements to our OSCAR IoT SIM Card Management Portal. There is now an API command for both Pooled and PAYG accounts, allowing a SIM reset. A SIM card reset takes the IoT SIM card off the network and allows it to re-register. Before now, this tool was only available on the Portal in the Service tab. There are many customers who prefer to manage most of the tools for their global IoT SIM Cards off the OSCAR management portal. This new API will help with initial troubleshooting of the IoT SIM.

New SIM Card Type Being Launched

For customers using the TCNS IoT SIM card type, you will start to see orders being filled with a new IoT SIM card named “TCNS – E”. This SIM will give you the same outstanding service you are used to, & will add some network operators. The most notable change is in Canada where we are adding Telus and Bell. Now all three major networks in Canada are available. There are also many other countries coming to this Multi-IMSI TCSN-E IoT SIM card. This is great news as we continue to grow our global IoT SIM card footprint and build more network redundancy!
