What is an M2M SIM card?

M2M SIM cards enable devices to connect to the mobile network in order to be able to transmit data automatically.

Unlike SIM cards for smartphones, an M2M SIM card can use the mobile networks from different network operators nationally and worldwide. It is therefore also called an IoT SIM card, multi-network SIM or roaming SIM. Data can be transferred securely via VPN.

The M2M and IoT SIM cards are managed via an online portal, especially tailored for the requirements of M2M communication.
