I cannot register to the network....[please help me]

Hello everybody..

i have try to send sms or make any phonecall using my GSM Modem, but the result always "wind 5,1 - NO CARIER - wind 6,1"

then i think, if no carier that mean i have not register my SIM to the network.

I used AT+CREG=1 and the result is "Ok - CREG=1,0" (The result must be CREG=1,1 that mean register process succesfully)

but, after that i still cannot send sms or make any phonecall??

Please help me

You probably need to do more than just run the CREG command. For example, is the modem associated with a specific carrier? If so, does the carriar have an allocated number for it? Finally, there's also an authentication process that has to be performed before you can make a call. The details depend on various factors such as the moderm's model, the carrier, the GSM version used etc.
