From smart meters and agricultural sensors to connected cars and industrial automation, the number of IoT devices in use has exploded into the billions. Yet behind every successful deployment is a lesser-known but critical component: the IoT SIM card.

In this article, we’ll explore what IoT SIM cards are, how they work, and why they’re essential to unlocking the full potential of IoT across industries in 2025 and beyond.

What is an IoT SIM Card?

An IoT SIM card is a specialized SIM (Subscriber Identity Module) card designed specifically for machine-to-machine (M2M) or IoT applications. Unlike traditional consumer SIM cards used in smartphones, IoT SIMs are built for durability, longevity, and the unique communication needs of connected devices.

Here are a few features that distinguish IoT SIM cards from regular ones:

  • Multi-Network Access: They often connect to multiple cellular networks in a region to ensure maximum uptime.
  • Global Coverage: Ideal for devices that roam internationally or are deployed across different countries.
  • Data Optimization: Support for low-power, low-data protocols such as LTE-M, NB-IoT, or 2G fallback.
  • Remote Management: Enable over-the-air (OTA) provisioning, monitoring, and diagnostics via a SIM management platform.
  • Long Lifespan: Designed to operate in harsh conditions and often last up to 10 years or more.

How IoT SIM Cards Work

Just like standard SIM cards, IoT SIMs identify a device on a mobile network and authenticate it for connectivity. The key difference lies in the backend infrastructure and software that supports them.

Most IoT SIM cards today can connect via private APNs, offer IPsec VPN support, and are managed through a SIM management portal, giving companies complete visibility and control over their fleet of devices.

For instance, an agriculture company deploying soil sensors across multiple farms can monitor usage, suspend or activate SIMs, receive alerts, and troubleshoot—all remotely from a central dashboard.

Use Cases Across Industries

IoT SIM cards are incredibly versatile and power a wide range of solutions. Here are some leading sectors where they play a vital role:

1. Connected Cars & EV Charging

Modern vehicles are equipped with embedded connectivity for GPS tracking, diagnostics, emergency calling (eCall), infotainment, and over-the-air software updates. IoT SIMs ensure vehicles stay connected across borders, making them crucial for automakers and fleet managers alike.

Vehicle Telematics Client Goes Global: Case Study

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

Introduction

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.

IoT SIM Card Deployments in Global AgTech: A Case Study

IoT Sim cardfor AgTech
AgTech IoT SIM card Connectivity

Introduction

As Agricultural Technology grows (pun intended) in popularity around the world, connecting all of these “things” is increasingly more difficult. International implementations face many obstacles. We focus on the issues with IoT SIM card use in worldwide operations. Some of the same complications occur in single country use as well. Streamlining these deployments saves time, money & headaches. This article focuses on one such case.  We will discuss a soil moisture sensor company struggling with their multi-national deployments. We will cover their solution, their initial problem, the steps they took to remedy the situation, and the solution they chose.

The Customer’s Description

As a Start-Up, this company needed to grow fast and were sending their moisture sensors all over the world, and they had pilots currently running in 27 different countries. Their solution includes a mesh network of wireless sensors spread over the fields of a grower and all of the data aggregated in a gateway device that sends all of the data back to a server for analysis and reporting on their UI. The gateway device is a standard rugged router. It uses a 3FF global IoT SIM card powering the connection to the back end through cellular networks. The gateway required bi-directional proactive communication because they needed to reach the gateway from time to time on demand.  Their sensors test the soil every 3 hours. The total amount of data per gateway averages 72MB per month.

The Problem

They struggled with how they would put together a solution for all of these disparate countries, though. It takes time and resources to find an IoT SIM card provider in each country. Using these various providers further complicates matters because they had to manage multiple SIM management portals, multiple APNs, SKUs for each IoT SIM card provider, and several languages to deal with (English, French, Spanish, Portuguese, Russian, Chinese, and German to name a few).

All of this takes time and resources. As a small company, their time really does mean money, because navigating all of the vendors, and programming their routers based on where the devices were being sent took time away from marketing and selling their solution. They estimated it took 47% of their time finding local cellular providers. Also setting up the new vendors’ APN’s and SKUs into their workflow, learning a new portal for SIM card management, etc., etc. That is all time when they could be building a strong sales funnel, meeting with new prospects, working on marketing  efforts, and so forth.  They estimated if they could focus 47% more time on these tasks, their annual revenue would grow over $1M.

What They Tried

Over the last 6 months they tried to standardize their connectivity providers to a smaller number. They thought this would solve the issues. What they discovered was that it did help, but the benefits were not sufficient. The CTO and COO still had to think about how devices needed to be configured for each country. They also had to manage multiple platforms which takes time to learn and implement different portals and the API’s each portal used (if they supported API’s). They also had different IP ranges to deal with, where a single IP range would be easier to manage because they could used a single VPN with a single IP range.

The OneSimCard IoT Sim Card Solution

OneSimCard IoT logoWe came to the table with our ears open. We heard their problems and developed a solution tailored to their particular needs. What we came up with was a single, Multi-IMSI, eUICC enabled  Global IoT SIM card. Our IoT SIM card  is used virtually anywhere in the world with a single APN. OneSimCard IoT covers 200+ countries and territories.  A single APN means they are able to set-up all of their devices the same, regardless of the device’s destination.

We also provided the client a single private static IP range large enough to support all of their IoT SIM card deployments for the foreseeable future. We recommended an OpenVPN solution for their bidirectional proactive communication to their cellular gateways. Because it only allows one concurrent user, OpenVPN is a low cost alternative to our IPSec VPN solution. It provides the communication this client needed, though.

The client also benefited from the use of our OSCAR SIM management Portal.  OSCAR is built in-house from the ground up. When a customer wants to make a change, we make that change quickly. This flexibility helps our clients by catering to their specific requirements without over-complicating the experience. OneSimCard IoT’s portal is cloud based and has mobile apps available on Google Play as well as Apple’s App Store. We also provide a full set of API’s to our Portal. This allowed the client to tie their portal to ours with only one set of API’s.

The Result

The benefit was immediate. Streamlining to a single provider gave the client back their valuable time. They now can concentrate more time and resources on revenue producing activities. In the first month since the change to OneSimCard IoT, they were able to implement 20% more solutions. They also were able to add 25% more new opportunities into their sales funnel. If 5% of these prospects close, this adds $1.5M in annual revenue.
