M2M SIM card: what is it?
M2M is the abbreviation for “Machine-to-Machine“: this term refers to objects capable of communicating with each other and exchanging information without human intervention.
The M2M SIM card is the technology that enables these machines to communicate. Also known as an “IoT SIM card”, it generally takes the form of a small chip embedded in an M2M device. It enables it to connect to a cellular network and to other devices.

M2M SIM card vs standard SIM card: what are the differences?
While the standard SIM card is suitable for consumer devices such as smartphones and tablets, it lacks the memory, software and physical capabilities to meet the needs of connected objects for professionals and manufacturers.
The M2M SIM card has been specifically developed by Objenious experts to meet the requirements of these machines: it is more robust and able to withstand harsh conditions such as extreme temperatures and vibrations.
Devices requiring an M2M SIM card are equipped with sensors to collect specific data (temperature, production output, etc.). This is why they are sometimes located in inaccessible places such as underground tunnels, vehicle engines, air conditioners, boilers, etc.
Designed to send and receive data, it also offers greater storage capacity. It also has its own software functions, such as a memory microcontroller.
In addition to its capabilities, the M2M SIM is the only card that complies with the regulations imposed by ARCEP (Autorité de Régulation des Communications Électroniques et des Postes). Companies are required to use M2M SIM cards with 14-digit numbers to connect their equipment. The use of conventional SIM cards for their IoT equipment is legally prohibited.
What formats are available for the M2M SIM card?
The M2M SIM card is available in all SIM card formats (cut-outs):
- Mini/Standard (2FF): with a thickness of between 0.68 mm and 0.84 mm, a length of 2.5 cm and a width of 1.5 cm, it is the most widely used card in the world today by phone models.
- Micro (3FF): smaller than the Mini, this SIM card is better suited to IoT devices such as smartphones with flat touch screens (tablets, smartphones, etc.). With a thickness of between 0.68 mm and 0.84 mm, it is 10 mm shorter and 3 mm wider than the Mini card.
- Nano (4FF): even smaller and thinner than the previous cards, this is the ideal solution for compact IoT devices between 0.60 mm and 0.70 mm thick.
- The soldered SIM card: this is integrated directly into the IoT device at the time of manufacture and cannot be removed by the user. Ideal for critical applications, it offers improved reliability and security, particularly against the risks of piracy and human error.
- eSIM: this is a digital version of the SIM card integrated directly into the handset. It allows you to change operator without having to change manually.
The M2M SIM card meets the needs of all manufacturers of IoT objects, whatever the size, design or future use of the device.
How to choose an M2M SIM card provider?
This essential choice depends above all on your devices and your needs. However, don’t forget that your needs will change in the future: if your objects are intended for a single location, it’s possible that your project will require global connectivity in the years to come. A reliable M2M SIM card provider offers :
Quality access to the national and global network
The M2M SIM must be able to connect automatically to the best local networks, wherever it is located. To make this possible, the operator must sign roaming agreements with other countries and national operators. This is a crucial criterion, particularly for use cases where connectivity is a key issue, such as healthcare. Without these specific IoT agreements, the SIM card will have no guarantee of being connected.
An intuitive management platform
To manage devices effectively, the IoT platform offered by the operator must be accessible and easy to use. Ideally, it should offer real-time visibility of your fleet and provide you with information such as the activity and location of your devices. Other functionalities will make all the difference, such as setting up alarms in the event of consumption anomalies, access to consumption history or incident management.
Flexible rates
To support your IoT project, choose an operator that offers customised rates tailored to your business needs. This avoids buying more data than you need, for example.
