Barred in UK. Works in any other country. Unlock is not available for the phone now but it should be in the near future. To be honest i was waiting for the unlock to be available again for two weeks. O2 premium service for iphone 5s is down and noone know when it will be back. Thats why im selling the phone and asking people to send me their best offers. We do escrow i dont see any problem for anyone.
