Hi! I'm living in UK right now and I have an O2 contract (iphone) but i'm leaving the UK for living in Spain in a month. I would like to find solutions about if I can use my iphone even if O2 blocks its imei. I intend to get a contract with Vodafone Spain and I don't know if my mobile will work. -Do you think that imei blocking affects only in UK and I could use iphone wherever I want except in UK? -Do you think it's better if I change imei number? (Is it easy? and Which ways I have to do it?) thanks a lot!
