ZTE have UK offices, though not sure if they'd be able to help if it was flashed with a different ROM.
+vat +customs charges probably nearer £130
We wear tin foil hats when in use.
Don't know how anyone can trust these phones
Problem with all non branded phones is NO SUPPORT AT ALL. Long time ago I bought a ZTE s6 and I can't do tethering the phone does not have the option after wasting several hours with no luck I was forced to return it.
