Hi ZoeMcD20
You have to maintain a UK address which doesnt include Isle of Man.
You will also be classed as permanently roaming, so you may also find restriction to service as o2 dont provide service on the Isle of Man.
If you are going to be on the Isle of Man for a long time you need to look at Manx Telecom or Sure (if it is still called that).
