Sim Unlock

[Anonymous]

Please Help me!
I'm from Hungary but I live from the UK now.
 I purchased an O2 mobile ( Nokia Lumia 710)
It's a very nice phone, and the O2 is an excellent service
But my problem is now. I need to go home to Hungary, (family reasons) and I need to change my Sim card,
for example: T-mobile, Vodafone, Telenor
But I can't change because my phone need an unlock code.
So I need an unlock code.
It is very important to me! 
I'll be back in England I will use continue my O2 Sim-card .

If the phone is being used on PayandGo, it has to have been used on the O2 network for 12 months before they will issue the unlock code. Cost is £15 but free if a contract phone and a contract phone can be unlocked at anytime.

Only Orange can unlock it. Did you buy it used?
