I have connected the GM862 to microprocessor and was able to place a call by issue ATD2xxxxx; command and able to send an SMS.
But my project requires connecting to internet and I am not able to esteblish a connection with GM862 to reach my web site. Here it is what I am getting:
AT+CGDCONT = 1,"IP","internet.gprs","0.0.0.0",0,0
OK
AT#SCFG=1,1,300,90,600,50
OK
AT#SGACT=1,1,"EASY GPRS","EASY GPRS","EASY GPRS"
+CME ERROR: activation failed
AT#USERID=""
OK
AT#PASSW=""
OK
AT#GPRS=1
+CME ERROR: activation failed
AT#SHDN
OK
Is it because of I do not know userid and password? When trying to find them in the phone I see “WAP connection preconfigured and cannot be modified”.
What could be a problem and what should I try to be able connect the GM862 to internet?
I know the SIM card does allow internet connection as it let browse internet when inserted into a phone. But I am not sure if does it use a USERID and PASSWORD.
Can you tell us what country/carrier you are using? Best guess is that your APN, userid, or password is incorrect - often Google is the best place to find the standard settings for a given carrier.
Depending on the carrier, WAP will probably not be sufficient for getting the Telit module on the Internet. You need a full GPRS connection. Once you figure out the settings above, you’ll have a better idea of what’s possible.

Note that some SIMs aren’t actually enabled for real GPRS, so that could still be a gotcha. But using these settings will get you closer to where you want to be
AT+CGDCONT=1,"IP","isp.cingular","0.0.0.0",0,0
OK
AT#USERID="WAP@CINGULARGPRS.COM"
OK
AT#PASSW="CINGULAR1"
OK
AT#SCFG=1,1,300,90,600,50
OK
AT#SGACT=1,1,"EASY GPRS","EASY GPRS","EASY GPRS"
+CME ERROR: activation failed
AT+CPIN?
+CPIN: READY
You mentioned
…some SIMs aren’t actually enabled for real GPRS…
How could I check my sim? I can browse internet when insert this sim card to a phone, does it miean the GPRS enabled on this sim?
AT#USERID="WAP@CINGULARGPRS.COM"
AT#PASSW="CINGULAR1"
AT+CGDCONT=1,"IP","isp.cingular","0.0.0.0",0,0
AT#SKTSAV
( you only have to do the commands above once)
AT#GPRS=1
(if successful, will show +IP: XX.XX.XX.XX)
Then you can do any of the socket, FTP, etc. commands
AT#SKTD=0,80,"google.com",0,0
GET / HTTP/1.1
AT#FTPOPEN="ibiblio.org","anonymous","test@nnnnn.com",0
AT#FTPGET="/pub/docs/books/gutenberg/2/5/5/5/25552/25552.txt"
To close the GPRS connection:
AT#GPRS=0
Still no success Could somebody help me to esteblish http connection from GM862 please?
I found by google an article “Carrier specific APN/TCP settings” and it says for AT&T APN: isp.cingular and for user name and password leave blank. I did but when it came to run AT#GPRS=1 it returns “+CME ERROR: activation failed”. I did as well like you recommended above and the same error (both termianl sessions are below).
Although I see when I run ATD99**1# I am getting CONNECT and could not get no more responce from terminal. I guess it is some kind of protocol, how to use that protocol and will it provide me an http connection?
Here from terminal console:
AT+CGDCONT=1,"IP","isp.cingular"
OK
AT#PASSW=""
OK
AT#USERID=""
OK
at#gprs=1
ERROR
AT#USERID="WAP@CINGULARGPRS.COM"
OK
AT#PASSW="CINGULAR1"
OK
AT+CGDCONT=1,"IP","isp.cingular","0.0.0.0",0,0
OK
AT#SKTSAV
OK
AT#GPRS=1
