are you aware of AT commands and using them?

I've used Siemens GSM modem in one project. I can send and receive messages without problems. First, you should see AT-commands manual. If you did this before, but you can't receive sms messages, it can be problem with COM port communications. Sometimes you can find information about this in the manual about AT commands for your phone. PS But I recommend you to use special GSM modems, because you will receive all needed materials in one box.
