We don't support 4G Roaming in Isle of Man, however, it is an inclusive Roaming destination so you'll still be able to use data as normal via 3G.
You can find our Inclusive Roaming destinations here.
You'll be able to use your phone for calls, texts & data just like at home, with the addition of being able to call Isle of Man numbers at no additional cost when roaming.
We'd highly recommend taking a look at our Community article which will help you prepare your phone for a trip abroad.
All the information you need on getting your phone ready can be found here
