Hi Guys-

I've used Wavecom modules in the Falcom Tango Module. Also the Telit modules, which I have a project with on at the moment. There are a few things to consider. If you want to use the available programming aids with these modules, and thus avoid using an external microprocessor, then consider that Telit uses the Python interpreter and the Wavecom modules have a whole development platform called Open AT based on 'C'. This is powerfully supported, and probably not for beginners. If you want to start by using just the AT command set for the modules, then probably the cheaper Telit solution would do for a start. Also the the Telit version of the Python language is easy to learn.

Good luck

Angus
