Does the SIM card that is in the camera have an active data plan? Check your account and see if the ICCID on that SIM matches the one for the old camera. If it does, make sure the data plan is current. Getting a signal doesn't mean the account is active. Think deactivated phones still being able to call 911.
In set mode, third tab, scroll down to Information, press OK. The IMEI and model will be there, I think.
