my aim to make a device when dc volt supply to device it call an specific phone number(which has fed) and noting else.
no supply current stay idle. need software coding and if possible in software coding , have space to feed phone number.
Let us know when you have settled all the details about which device, which power supply, what circuit will monitor the power and finally which microprocessor, programming language and GSM module you plan to use.
We will certainly be happy to help add space for a phone number in the software.
Aw come on…no prebuilt, handed over on a silver platter solution?
Sounds like a great idea. Go for it!
