I am trying to make a GPRS connection using a Windows dial-up session. It connects, and then it immediately disconnects.

- Make sure the APN is configured in the modem correctly (The APN is provided by the provider).
- Check the APN with‘AT+CGDCONT?’ To make sure it is correct.
- If no APN is inserted, then insert the correct APN using the command‘AT+CGDCONT=1,"IP","<APN>"’ with Hyperterminal or add it into the "Extra Initialization Commands:" in the modem’s properties.
- Make sure the APN is the correct APN for that account.
