I installed NOWSMS trail version. I tested it successfully in INDIA and US. I have a problem testing it with a dual band modem(850MHz and 1900Mhz ) with a Mexico SIM(Telcel). After inserting the SIM the NowSMS is responding the modem is not available.
I tested the modem against HyperTerminal too, it is not even responding to a simple AT command. a very few times it is responding with modem busy in initialization. The SIM is working with 1900MHZ GSM phone. What will be the problem.
This is very urgent. Please help us in finding the problem.

Thanks in advance,
Ram.
