Yet another "unlock code doesn't work" post.
My phone is a Sony Xperia XZ2. Entered my IMEI on the "unlock my device" page on the O2 website and got an unlock code (16 digits)... but when entering it, I just get "unlock UNsuccessful". Tried it a second time in case I mistyped it (since it *s it all out when entering it, so you can't double check visually) and same result.
Double checked the IMEI in the unlock code email matches the phone IMEI, also re-requested the unlock code typing in the IMEI again and got the exact same unlock code again (which I haven't bothered entering again, already entered it twice and it didn't work).
Any ideas? Or am I going to be forced to buy a new phone to use outside of O2 network?
Type *#*#SERVICE#*#* into keypad
[X] Network 0 = hard locked
[ ] Network 0 = unlocked
[X] Network 1-5 = attempts left
The phone app shouldn't matter as the data is stored in a partition in the operating system.
The only doubt I have is if the app isn't registering the keypresses correctly.
You could try again using the stock app and still have two attempts remaining if unsuccessful.
As long as the phone is asking for an unlock code it doesn't matter if the sim is active or not.
Tried it once more with the stock phone app as the default - same result. Down to 2 attempts now
Looks like the code O2 are generating for my phones IMEI doesn't match what the phone is expecting. Rather annoying if I have to buy a new phone just to use a different network, when this phone is still working just fine... other than being network locked...
The code comes from Sony so it's not generated by O2.
I'll ask @O2Georgina to contact you in the morning to check the details for you.
