M2M is the abbreviation for machine-to-machine and means that machines communicate with each other or exchange data. An M2M SIM card in turn ensures that machines and other devices have access to the internet or mobile network in order to transmit data. We provide an overview of the features and benefits of an M2M SIM card and why you should choose wherever SIM !
1,300+ companies worldwide rely on wherever SIM
If you want to buy a reliable M2M SIM card, wherever SIM is the right place for you: Our M2M SIM cards automatically connect to the best available local network - worldwide in over 190 countries and 485+ mobile networks.
Unlike with conventional SIMs, you retain full control over your data consumption at all times, activate SIMs flexibly in the customer portal and use tariffs that are precisely tailored to your IoT or M2M project - from individual devices to large-scale rollouts.
Unlike conventional network operators, wherever SIM provides you with a network-independent solution. Our M2M SIMs work in devices of all kinds - from alarm systems to industrial control units - and deliver maximum availability thanks to national roaming and global coverage.
An M2M SIM card is a SIM card that enables devices such as alarm systems, vending machines, trucks and many others to establish a connection to the mobile network and transmit data via it.
99,99 % availability through complete geo-redundancy of our data centers and a state-of-the-art architecture based on microservices.
Restrict the use of a SIM card to a specific device based on the IMEI (unique identification number of a mobile phone device).
Double protection when logging into the online portal: 2-factor authentication protects your data in the wherever SIM portal from unauthorized access.
The M2M SIM is to be understood as a kind of manual for the end device, in which it receives all the information it needs to establish the Internet connection. Accordingly, it is important that the end device is technically capable of processing the information provided by the M2M SIM. Successful IoT communication therefore requires both - a reliable M2M SIM card and an intelligent end device.
Strictly speaking, there is no difference between an M2M and an IoT SIM card. The two terms are often used interchangeably, even though IoT and M2M themselves do not actually mean the same thing.
Since M2M and IoT SIM cards are both technically SIM cards that provide information for connection to the mobile network, the difference between IoT and M2M is irrelevant for use. The devices in which M2M and IoT SIM cards are used are enabled by the SIMs to transmit and receive data. So if you are actually looking for an M2M SIM card, you can also use IoT SIM cards.
Whether mini (2FF), micro (3FF), nano (4FF) or embedded (MFF2): Our SIMs are available in all formats - including as a particularly robust industrial SIM with a long service life, over 1 million write cycles and 15 years of data retention.
On request, we can provide you with your own private IP subnet (a private APN). Access to the IoT SIM cards is therefore only possible via a secure IPsec VPN connection and is protected from third parties.
On request, we also offer you the option of using a static private IP address for the M2M SIM to easily access the SIM and device via a secure VPN. For secure and simple remote access, we also offer VPN on request.
In order to meet the different requirements of end devices and machines, the SIM formats have been and are constantly being developed further. To ensure that the SIM cards themselves take up as little space as possible, the size has been significantly reduced, leaving more room for other components if required.
A basic distinction is made between the mini, micro and nano SIM card formats. There are also embedded SIMs, which are soldered directly into the modem as a chip. In addition to the standard version, the different formats are also available as "Industrial SIM". This more robust variant is designed for an extended temperature range and a longer service life, for example.

M2M SIMs have information and, if you like, "access keys" so that end devices can use a variety of mobile networks from different network operators both nationally and internationally (national roaming). This means they enable a connection for IoT and M2M projects almost everywhere.
Conventional SIM cards, especially in Germany, usually only provide the information for network usage of the SIM-issuing network operator, i.e. the provider with whom the mobile phone contract was concluded. However, the availability of this one network varies depending on the location: sometimes there is good reception, sometimes there is none at all.
To avoid connection interruptions in IoT and M2M projects as far as possible, M2M SIM cards also enable the use of different network operators in Germany (e.g. Telekom, Vodafone and O2 in Germany). M2M SIM cards are therefore also referred to as multi-network SIMs or roaming SIMs.
M2M SIM cards are connected to a platform for easier management. Both the SIM cards and the associated endpoints are configured via this platform. For example, service profiles can be set up for M2M SIMs, SIM cards can be activated and deactivated or mobile networks can be excluded for use(blacklisting).
Comprehensive monitoring is also possible via such portals. Users can see the status of the end device, whether and to which network the SIM card is connected and how much data it is transmitting. In the event of a problem, various diagnostic functions such as a remote reset of the SIM card can help.
At wherever SIM , we offer a clear online portal and a comprehensive API for easier management of the M2M SIM cards, which can be used to transfer the data from our portal to your own systems.
