Abstract
A system and method of remotely changing use of a cellular protocol at a vehicle includes: storing, in a network access device (NAD) at the vehicle, identities of one or more cellular bands that provide cellular service according to an up-to-date cellular protocol; wirelessly receiving at the vehicle a computer-readable instruction that deactivates the up-to-date cellular protocol; and in response to the computer-readable instruction, the vehicle: obtains the identities of the cellular bands stored in the NAD; stores the obtained identities in a non-volatile memory device located apart from the NAD; and erases in the NAD the identities of the cellular bands that provide cellular service according to an up-to-date cellular protocol.
