I am seeking help on designing a very simple and low cost (if possible) GSM modem module. The modem is required to only send SMS's to mobiles (not receive).
This design is to be integrated into a PIC microcontroller project that I am working on.
Has anybody already done this and can help me ? Where do I start ?
when u take gsm model is complex when compare with PHS std. so take PHS std and decrease QoS to only send SMS . then it will help ur project to finish soon.
