GPRS shield V 2.0 problems with http request

Products & Technology Shields
#1

Hi all.

I just bought 2 gprs V 2.0 shields. I’m trying to make a http request through AT commands. I have used the tutorial on the seeedstudio wiki on the shield. It all seems to work except when I want to connect to a bearer. It simply won’t connect.

When I make a http request:

I get this response:

I have a SIM card from Telenor and I’m using it in my smartphone for accessing webpages, so I’m sure that the SIM card works for gprs.

Does anyone have an idea I can work from?

Thanks

Hi all.

I have now come further. My solution was to do this:

AT+CPIN?
AT+CPIN=1234 (or what ever pin you have)
AT+CGDCONT?
AT+CREG?
AT+CGACT?
AT+CMEE=1
AT+CGATT=1
AT+CGACT=1, 1
AT+SAPBR=3,1,“CONTYPE”,“GPRS”
AT+SAPBR=3,1,“APN”,“internet”
AT+SAPBR=1,1
AT+SAPBR=2,1
AT+HTTPINIT
AT+HTTPPARA=”URL”,”www.m2msupport.net/m2msupport/test.php”
AT+HTTPACTION=0
AT+HTTPREAD
AT+HTTPTERM
