registering unlocked phone from another country

Posted by mojo_jojo
Hi,

I've been given a mobile which was on a contract in Poland. It's been unlocked and will work in the UK with an O2 SIM. I have an unused O2 SIM (not registered). Will there be any problems from O2 f I register the phone with them and activate the SIM card?

You dont need to register to use the handset. Just put the sim in and it should work.

But the sim is brand new and not used/registered? I was just wondering if there would be some sort of problem getting 02 to activate a new SIM on a phone from another country?
