I ask because old GSM modems and shields stop working after day or two. They start working when power goes off and then on again. Worst part is that it is difficult=impossible to see from sketch, is the modem working or not.

It does not help with the current a few years old shield. Everything seems to work, but the shield does not send or receive SMSs.
