GPRS can't connect to Server

Wireless & IoT
11

I hook in, in this topic because it seems to be that I have the same problem. In another topic I tried to connect to a website but it failed. In this forum I found other AT commands to connect with a server I tried that also. First i will show you my at commands.

Local echo on so I can see my http requests send to the website

at+cpin=0634
at+cpin=0634

AT#USERID="tmobile"
AT#USERID="tmobile"
OK
AT#PASSW="tmobile"
AT#PASSW="tmobile"

NO CARRIER

Follower mentioned that it will work without at#gprs=1.

I tried that also:

at+cpin=0634
at+cpin=0634

AT#USERID="tmobile"
AT#USERID="tmobile"
OK
AT#PASSW="tmobile"
AT#PASSW="tmobile"

AT#SKTSAV
OK
AT#SD=1,0,80,"www.telit.com",0,0
AT#SD=1,0,80,"www.telit.com",0,0
ERROR

That isn’t working.

For a extra check I tried with a telnet session on port 80 of the http://www.telit.com and that is working fine with the following commands

GET / HTTP/1.1
Host: www.telit.com

Also I tried AT+CGATT? and is returning 1

Command AT#SERVINFO is returning.

#SERVINFO: 998,-51,“Ben NL”,“20416”,64,0172,00,1,“I”,00,6

So gprs is supported.

I really don’t know what I can do more. I hope somebody here can tel me.
