Hi,

I just wanted to share a configuration we use to get our devices registered on T-Mobile's GPRS network. This assumes you have an active HyperTerm session with the device:

AT+CFUN=0 // Deregister the device from the network
AT+CGDCONT=1,"IP","m2m.t-mobile.com // Setup the access point name
AT$AREG=2 // Setup auto GPRS registration
AT&W // Save the settings
AT$RESET // Reboot the device

Now you can verify GSM status by issuing the following command:

AT+CREG?

You should see either +CREG: 0,1 (home network) or +CREG: 0,5 (roaming). To verify a valid GPRS session you issue the following:

AT%CREG?

You should see either %CREG: 0,1 (home network) or %CREG: 0,5 (roaming). Now check that you have an IP address and you're good to go:

AT$NETIP?

If you see all zeroes then something is wrong. Repeat the steps above or come post a message here and we'll be glad to help you out.

Actually, that is our configuration for using Raco's (a TMo reseller) GPRS network. The APN name would be different if you acquired your SIM directly from TMobile.

It looks like you are missing the closing quote on your commands.

Try changing

AT+CGDCONT=1,"IP","gprs.qtel

to

AT+CGDCONT=1,"IP","gprs.qtel"

hey ,yahoooo...!!!!

it worked..
thank you so much..

at$cgeer
$CGEER: no PDP reject cause

OK

It looks like you are not even getting on the GSM network, so things are not even getting far enough for the APN name to matter. Can you try this SIM in a phone to make sure it is activated?

Try going through the following commands, they may provide some clue:

AT+CMEE=2 -->enables extended error reporting
AT+CFUN? -->expected response +CFUN: 1
AT+CPIN? -->expected response +CPIN: READY
AT+CREG? -->expected response +CREG: 0,1 or 0,5
AT%CGREG? -->expected response %CGREG: 0,1 or 0,5

I moved the Qtel (Qatar) settings into their own thread here.
