Which GSM modem/module to start with?
Wed Apr 28 2010, 09:30 pm
I want to get a GSM modem to play with and learn AT command etc as I will have to use one as part of a college project next year.
Wondering which one I should start with or is there much difference.I will probably only be using it for sms (atleast to begin with), I know I need AT command and RS-232 support, is there anything else I should look out for.
Regards,
V

Before buying a SIM300 unit take a look at this thread.

To use the item off ebay you need a lot of extra bits, such as an adapter board
costing more than the modem.
Consider this item or similar as it appears to come complete.
