What to do if Maestro M100 2G LED lights but doesn't blink after power up?

If the Maestro Modem's LED lights up but doesn't blink after powering on, ensure a valid SIM card is properly inserted and is not locked (check AT+CPIN command in the AT command guide). Also, verify the external power is correctly connected, network coverage is available, and the CTS/DTR pins of the serial port are not connected.
