How do I unlock an o2 phone?

[Anonymous]

I have a Microsoft Lumia 640 LTE that my son used when he first had his o2 acc. Now he uses a different mobile and I want to unlock the Lumia for my daughter to use on another network. How do I get it unlocked?

You will need to use your sons original SIM card I believe to do it

Any o2 sim is fine but if you can use a contract sim to register the phone the unlock will be free.

Otherwise you'll have to pay £15 and use the PAYG option.

I always thought you needed the original sim that came with the phone

Nope, not at all mate.

Call 02 and ask them to get you an unlocked code, or go to a phone stall and it will cost you 10-15.00

@Anonymous If they do that then they void any warranty they may have on their phone & those market stall types are not guaranteed to actually work
