My daughter's phone became locked by Mobile Rescue the other day (Saturday evening). I spoke to someone on 789 who suggested I speak to the insurance team the next day. I did that and we had the phone unlocked pretty quickly.
However, my daughter then pointed out that the phone was saying 'No SIM'. I called 789 again who ran a diagnostic, then suggested they send a replacement SIM which arrived yesterday, but that if that didn't work they'd need the phone sent in for repair(!)
However, the phone is still not functioning other than on WiFi. It no longer says 'No SIM', but any attempt to make a call results in 'Not registered on network'. Searching for a Network Operator in Settings finds none at all.
Has that damn Mobile Rescue software really damaged the phone!?
