I have a Lumia 640 XL LTE Windows 8.1 update 2 firmware 1.2.17.0.
The phone is about 18 months old locked to Vodafone, but ive been trying to unlock using codes i have got from ebay, they come up with same code but this wont work and have been told i might need a Master code, but not sure how to add this and where to get it from.
Any help would be great
