Digi Embedded Yocto includes support for the following cellular modems:

Digi XBee Cellular LTE Cat 1
Digi XBee Cellular 3G Global
UBlox Toby L-200/L-210
Telit LE910
Telit HE910

See Configure cellular network settings for instructions on how to configure your cellular network.

Known issues

When you are using ModemManager, the initialization of some cellular modems could fail if there is no power cycling of the card between two initializations. This could happen during a software reset. To avoid this situation, we recommend you incorporate a mechanism in your carrier board to power cycle the modem at boot time.

Limitations

The cellular support in Digi Embedded Yocto is based on the NetworkManager and ModemManager open source software packages.
