hi !
i want to send text msgs from my AVRmega micro, how easy or difficult it is to interface this module to my micro ?
does this module has all hardware built in and just needs to be programmed? does all local carrier SIM works on it like T-mobile, AT&T , Verizon etc ?
any guidance is highly apprciated.
thanks

also the datasheet of this SIM900 module saying voltage between 3.4-4.5 V
but the userguide is saying to use an DC 5v 2.5A adaptor.
which one is true?
