I have an issue with official Arduino GSM Shield I can not open a webpage even when I used the example (GSM web server) ?! I am using Arduino Mega 2560 with GSM shield and I put the jumper in pins 2 and 10 I have used three different SIM and all of them have internet active and support GSM,GPRS and EDGE... I used 1.0.5 -r2 Arduino environment. the only thing I got is the IP address but when I put it in browser is not open the page !!!
I appreciate any help
