I've recently purchased a second hand iPhone 5. They demonstrated the phone making calls before I purchased it.
Unfortunately the phone isn't being recognised by iTunes, and is also very frequently showing me the message "No service". I did however very briefly have service earlier today, enough to send and receive a couple of SMS's.
The things I have tried are:
- Restarting laptop,
- Trying another laptop,
- Uninstalling and reinstalling iTunes (on both laptops),
- "Reset Network Settings,
- Rebooting phone,
- Airplane mode on / off,
- 4G on / off,
- Updating all software,
- Trying to turn off automatic carrier selection, but I get the message "Unable to load network list",
- "Reset All Settings",
- Trying many mixes of restarting with cables in and out and every different USB port available to me,
- Offering my lunch to the gods.
The software involved is:
- iTunes 12.1.50
- iOS 8.1.2
- OS X 10.10.2
I've also checked and the phone is definitely unlocked, and marked as last activated yesterday when I first tried to use it.
I would be greatly appreciative of any further suggestions.
