AT&T related help: Get a replacement SIM
How can I configure the APN for a SIM card in my car?
My old SIM card became defective and today I picked up a new SIM card at the AT&T store. Now the car is asking me to configure the APN for the card/car. AT&T sent me to my car dealer who showed me the manual where it says this can only be done by the service provider. Tech support also sent me to the car dealer. How can I solve this?
