A secure global connectivity solution.

Datamobile AG uses a non-controlled multi-roaming function for its SIM cards, which ensures a secure global connectivity solution. The cards actively search for the strongest network in their area and switch providers as soon as a weak connection occurs. This is a must for IoT devices that rely on uninterrupted connectivity.


In this example, Datamobile receives four different network options. These can be national or international providers. From this point on, the multi-roaming SIM card chooses the strongest connection with the best reliability (Provider B). If this changes over time, the SIM card swaps the network in a few milliseconds to ensure the most stable and best connection continues.
