Hi,
I am starting to design an alarm transmitter using both GSM and GPRS .
I'm looking for a simple and cheap one with an analog audio interface (for transmission vocal message via GSM) and a data input (for transmission via GPRS).
I don't need TCP/IP or other internet protocols !!
I don't need also many supplementry features that would, uselessly, raise its price .
So, Any sugestions about GSM/GPRS modules?
Thanks in advance.
