Does your GSM modem and the service you signed up for support SMS? Can you send an SMS to a GSM phone?
I have found that SMS is unreliable between different service providers, even if both are GSM. This is especially true with pre-paid services; the post-paid (monthly contract) services are more reliable.
Modem works fine with other GSM phones (able to send SMS) ... Infact I've never had any problem. I have 2 modems, one sends SMS to both GSM & CDMA, with the other I have this problem. So it has to do with the modem I guess ... rather than the Network operator.
Thanks & Regards,
