Manx Telecom's released a list of handsets which won't be able to use its 4G network when it's turned on.
If you have the latest Apple phone, prepare to be disappointed: the company says the iPhone 5c and 5s won't be able to use its high-speed broadband until a software update is released.
For Android users, it's some 4G-ready Samsung phones that create problems.
Photographer Gary Weightman says he's surprised he won't be able to use 4G, despite using it in the UK:
