Hi. Can someone give me some advice on a problem. 4 days ago I had a message on my mobile 'Invalid SIM Card. Network locked. SIMcard inserted'. I contacted Virgin who eventually advised there was a problem with the SIM card. They sent me a new one which arrived today but I still have this message. I contacted Virgin again who advised me that I'd need to speak to Carphone Warehouse where I bought the phone 3 years ago to unlock it. The phone is a an old Samsung Galaxy Core Prime. Has anyone else had this problem?. I thought it a bit strange that I would need to contact CWr to resolve this. Any help would be appreciated.
I've been with Virgin for over 10 years and the message just came on when I switched the phone on a few days ago. I last changed the SIM 3 over 3 yeas ago when I bought the phone. Unfortunately I don't have another phone to check it in. It's really frustrating as when I first contacted Virgin they advised me that I just needed a new SIM and when that arrived and didn't work they advised me to go back to the shop I bought the phone to unlock it which doesn't really make sense to me but I could be wrong.
