I bought an iPhone SE from Carphone Warehouse sim free, I used my existing Virgin sim with it to which it has now locked to Virgin. I have rang customer services several times now asking for a Network Unlock Code (NUC) as I want to leave due to coverage issues and poor internet connection. Virgin was great in providing me with the PAC code but cannot or will not provide me with the NUC code as they say I did not purchase my phone with them. So I now have an iPhone I cannot use. As you can imagine I am feeling more than frustrated at this point, has anyone else had a similar issue and found a solution?
