Hello!
I want to start a project that has been in my mind for some time, and I need a GSM oem module to remotely send messages to my controller. I only need it to decode DTMF, not real modem features, but this wouldn't bother. I need it to be very easy to integrate and cheap, because it is a project for myself and I cannot waste too much, just in case it doesn't work...
Thanks in advance!
