No service on phone but ICCID shows in About
I've got an iPhone 6 where it constantly looks for service.
I've tried 3 different sims.
The SIM card shows in the ICCID field under Settings > About.
I've swapped the logic board into a new phone case\shell where that housing\cellular previously worked, however, I still get no service.
Is cellular service linked the the logic board somehow?
Is this a good question?
