Wild speculation based on poor RF understanding:
If I were putting a back door in cell modem silicon to track the device when it's totally powered off, I'd do something like a passive RF bug. Surely you could get something like an RFID circuit to hang off one of the many antenna in a phone. Then you just give it a path to a unique id, maybe derived from the MAC or something.
