I've recently upgraded to an XZ1 Compact, and intend to keep my Z5 Compact as a spare phone. In order to do this I need it to be Network Unlocked as I've switched from EE to O2 (UK).
EE supplied me with an unlocking code which didn't work, as it turns out the Network Unlock Code Counter is at zero (despite me never having attempted to unlock the phone before).
Sony are insisting that the only way for this counter to be reset in order to allow me to enter an unlocking code is if I send the phone to them for an engineer to do it. I can't believe in 2017 that this is the case, and there isn't some way of doing so remotely or even myself.
Does anyone know if this is the case or have any idea how to avoid having to send my phone to Sony?
