Instead of doing that, I'd simulate "network loss" by substituting a 50 ohm dummy load for the output antenna. This assumes that it is a connector, not soldered right to the board.
This way, there is no "fault" other than not being in a cellular-coverage area.
Since FCC testing is expensive, I would not doubt that many manufacturers just make one card to install into multiple cars (to lower the FCC testing cost). That would be the best case, as all you need to do is find and remove that card.
