Wirnet iBTS and Wirnet iFemtoCell are able to send and receive SMS if the mobile network is properly configured. Modems are identified by manufacturer_X where X is a number. This can vary for the Wirnet iBTS if it is a dual-SIM device (always 0 for Wirnet iFemtoCell). The manufacturer is always sierra for Wirnet iBTS.

To retrieve the identifier, use the gsmdiag.py command.

Here is an output of /tmp/gsmdiag.txt. Two modems are displayed, and only one has a SIM card present. Its identifier is /sierra_0.
