I've just changed from BT to ID Mobile, on a SIM only deal, using my own second hand iPhone. When I first attempted to put the SIM in the mobile, a messaged showed saying that the phone needed unlocking, however, I find this strange, as the phone isn't locked. It was previously on a different network before I had the phone, but switched to my old BT SIM without issue.
To complicate things a bit...
In order to Activate the SIM, I put it in another phone and it worked ok. However, when putting it into my iPhone the error has now disappeared, but the phone simply says it has "no sim" (where the network is usually displayed). I have noticed some scratches on the SIM, so don't know if these are causing some of the problems.
To summarise:
- Is there a reason that the SIM wont work on a second hand iPhone 5?
- Is it possible to get a replacement SIM as mine appears scratched?
