I am trying to initiate a data call between two Nokia 30 through GPRS (The GPRS service is available in our city), they are both connected to PC. Firstly, i set up a voice call between the twos, at sending side HyperTerminal, i entered AT command as "ATD139XXXXX;",the receiving side HyperTerminal received "RING", after entered "ATA" at receiving side, the voice call was set up ok!
While i tried to set up a data call between the twos. I entered "ATD139XXXXX" at sending side, responsed with "NO Carrier", and i couldn't set up the data call. Why?
Thanks a lot!
