Nokia Lumina 520

[#1]

Hi all, I bought a Lumina 520 to use whilst on holiday in the US last month. It's locked to AT&T. Whilst the net shows loads of clips and sites offer unlock codes, I'm being told a code isn't available for this phone. Surely some mistake. It's a neat 4g phone and I'd like to move my GiffGaff sim to it. Any ideas?

Hi there @partings  and thanks for visiting the community.
For your device to work on giffgaff,then it needs to be unlocked or locked onto the o2 network,giffgaff runs on the O2 network,and there are a number of ways that this can be achieved.

1) Contact your current service provider (if you have one) and they can unlock your device for a small fee.

2) You can take your device to any phone shop or market stall and also have it unlocked on O2,again for a small fee.

3) There is an unlocking service for most devices,and there are also many websites than can unlock your device,and maybe for FREE.

Please find below 3 links that can help to unlock your device thankyou.
