Hi guys. Would like to ask you what are the differences between unlocked / SIM free Lumias bought in the UK and in Slovakia for example? I am planning to buy Lumia 640's for our parents. I was thinking to buy them in the UK and then take it to Slovakia. I know, that I can change the language of the phone... Seems to work fine in Slovak language... Would they be limited, something like LTE would not be compatible or everything should be fine?
