What is the definition of an M2M SIM card? How does it differ from a standard SIM card, and what are the reasons for choosing to use one?

What exactly is an M2M SIM card? What is the difference between a normal SIM card to an M2M SIM card and why should I use those? These are a few of the most basic questions when it comes to the topic of M2M SIM cards and in this blog post, we want to provide you with the most important answers.

What is an M2M SIM Card?

To understand what M2M SIM cards are in the first place, it is necessary to explain the term M2M. This is in fact the abbreviation for the term machine-to-machine communication. Knowing this now, it is easy to understand that M2M SIM cards are for those very products that transmit information from one machine to another. To make it easier to understand, you can also imagine that through these SIM cards, the devices have the ability to talk to each other.

Introduction to M2M SIM Cards

M2M is an abbreviation for machine-to-machine communication. As the name suggests, M2M SIM cards enable machines to communicate with each other. IoT Devices for smart homes and building automation are popular examples of IoT devices communicating with each other for a connected ecosystem.

But which devices exactly are meant by this?

Whether we know it or not, in our daily lives, we often encounter products powered by M2M SIM cards – e.g., wearables, smart home devices, sensors, and industrial and medical devices. Those products must communicate with each other or, very commonly, cloud-based applications to be fully functional. 

How M2M SIM Cards Work: Enabling Machine-to-Machine Communication

M2M SIM cards have a functionality similar to that of a normal SIM card. Here, the key difference is that M2M SIM cards use cellular networks to exchange information with each other instead of a user interacting with the machines. 

Machine-to-machine communication can help automate a sequence of actions for smart devices. M2M SIM cards use IoT connectivity through cellular internet to exchange information between M2M devices. These SIM cards function the same as normal SIM cards; however, they have special tariff plans that are ideal for M2M data exchanges.

What is the difference between M2M SIM cards and traditional ones?

As outlined above, M2M SIM cards are designed to communicate between devices and towards northbound applications of two machines. Hence, the main use cases for M2M SIM cards are in the automotive, industrial, logistics & telematics, and medical sectors. In contrast, traditional SIM Cards are mainly used in consumer devices like smartphones or tablets. But this is not the only difference between those two types of SIM cards. On the other hand, they also differ in the following points:

  • Durability of M2M SIM cards

Unlike normal SIM cards, M2M SIM cards are often used in remote areas where harsh conditions prevail. Since the normal SIM cards used for consumer devices are not made for such conditions, M2M SIM cards are designed to withstand more. Moreover, M2M SIM cards can last up to a decade.

  • Higher storage capacity of M2M SIM cards

Another difference between M2M SIM cards from normal ones is that they have a higher memory capacity. IoT devices are often placed in remote locations, and a lot of data is sent there, which cannot be deleted regularly.

  • Global Scalability and Roaming Capability of M2M SIM cards

As in many IoT and M2M use cases, mobility of the devices and cross-border communication is a key requirements; the M2M SIM cards are usually assigned to tariffs with harmonized regional cost structures. M2M SIM cards and IoT cellular connectivity are the only ways to successfully power an international and even global-scale network, especially with M2M eSIMs. We can enable devices to send and receive data from any place with cellular coverage using an M2M SIM card (which is virtually everywhere in the world).

  • Security of M2M SIM cards

As a result, in the core network of mobile network providers, traffic from M2M connections is most commonly isolated from the rest of the data traffic. Usually, private access points, or APNs, are used to achieve this.

  • Management platform for M2M SIM cards

Another critical difference is that M2M SIM cards are usually being managed via a platform. This allows you to manage the many SIM cards and your end devices in one portal. Learn more about freeeway’s CMP (Connectivity Management Platform)

  • Accounting

In contrast to regular SIM cards, special data tariffs are offered for M2M SIM cards. In addition, the standard approach of data pooling allows one device’s unused data volume to be passed on to other devices. As a result, the tariff bundles are usually better utilized.

Choosing the Right M2M SIM Card: Key Factors to Consider

The key to choosing the right M2M SIM card is to consider a set of parameters that are given in the below list:

  • The cost of M2M SIMs
  • The ideal SIM form factors
  • Availability of the tariff plan that meets your needs
  • Global IoT support for the mobility needs
  • Private network communication to protect against attacks

The Benefits of M2M SIM Cards: Improved Efficiency, Cost-Effectiveness, and Scalability

Here are the different reasons to use M2M SIM cards in comparison to traditional IoT SIM cards:

  • Tailored IoT Data Plans:

M2M SIM cards always come with plans that are specific for machine-to-machine applications. M2M SIMs provide tariff plans that address the need for M2M data exchange and cost-effective infrastructure.

  • Dedicated IP address:

In some cases, M2M infrastructure also utilizes fixed IP addresses. A dedicated IP address is a key to securely transmitting data across connected M2M devices.

  • Environmental durability of M2M SIMs:

Often the M2M SIM cards have to serve applications in a variety of environments, such as automotive or industrial applications. Here M2M cards are crucial as they are durable to withstand extreme temperatures and harsh conditions.

  • Remote control & access management:

M2M SIM cards can help remote control and access management for a large fleet of IoT devices. These SIM cards can also be limited or deactivated remotely if the network administrator demands them.

Our IoT SIM Tariff & Pooling Options

At freeeway, we offer two pricing and two pooling options to provide you with the right product.

Pricing Options:

  • Postpaid Pricing of M2M SIM cards

At the end of the billing cycle (usually aligned with the calendar month), the consumed data volume and SMS are charged. In addition, the invoice highlights the different data bundles, SMS and M2M voice consumption, and out-of-plan fees.

  • Prepaid Pricing of M2M SIM cards

Optionally you can select a prepaid model that provides a per-price-plan level, an MB data bundle, and a validity period, e.g., 500MB for 24 months.

Pooling Options:

  • Static Pool for M2M SIM cards

Where a certain number of data, i.e. 500GB, is provided monthly. An infinite number of SIM cards can be assigned to the static pool and consume from there. After the pool is consumed, you have the option that another pool of the same size is opened or that a second smaller pool, i.e., 50GB is added for this billing cycle. The system will start again in the following billing cycle with a static 500GB pool.

  • Flex Pool for M2M SIM cards

A Flex pool allows you to use the data allowance of multiple SIM cards within a price plan. With every additional activated SIM card, the overall pool for you increases. The price plan consists of a data allowance per SIM and an over-usage rate per zone. In case that the data allowance is used up, the SIM card is NOT deactivated.

Price plans can be changed at any time during the month. The price plan set on the last day of the billing cycle (month) will be charged.
