Hello,
  I am using the arduino M10 gsm shield to send 1 sms per min, it works fine for a while (a week or so) but sometimes It randomly switches off on its own.

  I was wondering if anyone else has had this problem before, for now one thing that I can think about is that maybe the power supply is failing during some transmission surges and dropping below 3.3V, but again if that was the case shouldn't it happen all the time and not once every one or two weeks ?

Thanks !

Personally I'd be checking the modem is awake before sending every message - then it can never get away from you.
Ask the right question, which can be hard for beginners, but this doesn't mean that google is broken.
