Hi, first you need to make sure about the GSM card itself weather working normal or not, please try to use the simcard to other GSM phone to check it. If GSM card is ok, then put it again to Samsung Galaxy S3, and try to make sure the Flight Mode is not activated. The last try you can do is performing hard reset will reinstall factory default firmware or operating system and make all setting back to normal again.
