Moderator edit:edited for language

well, I have a lot of problems too. But most time it works.

Did you consider the tips on
file:///H:/Arduino/Info/GSM-shield/Arduino%20-%20GSMShieldLeonardoMega.htm ?

The pins for serial communication with the GSM module on Mega are different from the pins on Uno.
