Xperia T NCK locked
Hello,
I have bought to myself with Ebay a Xperia T with Branding from AT&T. When I have called the service menu to me, I had to ascertain network is locked. Which possibilities do I have in the device with a code to unlock? Can somebody help me, please ???
Enter the code(*#*#7378423#*#*) -> Service Info -> SIM lock
[x] Network 0
[] Network subset 0
[] Service provider 0
[] Corporate 0
[] SIM 0

I'm sorry to say, it would appear as the the phone can't be unlocked. The number after [x] Network shows the number of unlock attempts left and in your phone it shows 0, which is bad. Maybe some service station can do it, but unlock by code won't work anymore.
