Hello,

without details we can not help you.

  • So what is the problem?
  • What is your MbedOS version?

If you are familiar with AT commands of this device, then you can also use ATCmdParser API. That allow you direct control via AT commands without additional library - ATCmdParser - API references and tutorials | Mbed OS 6 Documentation

For the library from above will be Mbed OS 5.15.9 recommended, because the library is based on an old Serial API what is not included in MbedOS anymore (was splited to two APIs Buffered and UnbufferedSerial).
