I have Q2501B with firmware 6.0sgg and I can’t make any GPRS connections.
I try to send below commands sequence:
at+cgdata=1 or atd*99#
I don’t receive no answer for command at+cgdata and modem is still remained in AT command mode. When I make the same operation on the Q2501B with firmware version 6.0kgg everything is OK. Could anybody help me to resolve this problem?
Thaks in advance
