Quite a clever idea to just bypass the battery and connect it to the 5V USB (assuming your phone will handle the 5V) so that the phone is always connected, and just starts up with the vehicle. It was equipped with a SIM that shares the same number so that it operates like the primary phone.
So nothing major required here apart from the tweak to have the power connected up. Perfect for that excellent old phone you have just lying around because its battery died, and it’s non-replaceable.
