Enter SIM ME lock on my Alcatel U5 phone with existing SIM with Virgin
I have had my existing pay monthly SIM with virgin in my Alcatel U5 phone for some time. I turned my phone on a few days ago and on the screen it says “Enter SIM ME lock” and beneath the key pad it says Network locked - Emergency calls only. If I put it on Airplane mode on WiFi it lets me use Facebook and I can hear notifications. It’s strange as it’s not a new SIM and has been working well up to now. I’ve not been able to make calls or texts for 3 days. My wife has called and messaged Virgin from her phone but they have not got back to us. Any ideas how to solve this please?
