I'm doing this in a little project.
The main problem with talking to a GSM system that will send and recieve SMS
messages is that most of them will halt as they recieve a message even if
you are doing another action like reading the previous message.  This causes
very erratic behaviour in a system where a lot of SMS'es will be send and
recieved in a short time.

If you only will be sending, or doing send / recieve very infrequently, then
you can safely asume the modem/phone will actually do and perform as
expected.
