Hi, I have an iPhone 6 that I bought in the uk and used for over a year on Vodafone UK. I moved out here and unlocked my phone to use on Vodafone NZ (5 months ago). I am now returning to the Uk and wondering if my phone is now locked to Vodafone NZ? (I wouldn’t be using Vodafone UK when I go back to the UK). I tried to use the requesting an unlock code on this website but it says the number is not in the system. Any help would be appreciated.
