Roaming and maritime networks

Ollie2222 — Fri, 28 Feb 2025 15:33:01 GMT

I have a BT Mobile Sim only with EU roaming included.

I'll be travelling to Norway soon by boat and will be near the coast quite a bit where I should be able to connect to the land based Norwegian networks so my understanding is this is fine and included.

If I go out of range of the land based networks then there is also Tampnet which covers the north sea and is recognised as a maritime network with huge roaming costs.

Other than manually setting the network to the local Norwegian network to prevent this is there any way I can avoid it connecting to the maritime networks?

On EE it is possible to text ROAMEU to 150 and it limits roaming to include EU locations only stopping any potential eye watering bills if the phone connects to the wrong network but I've tried this and it appears it doesn't work on BT mobile, is there anything else I'm missing?

Hello @Ollie2222.

Thanks so much for coming here.

If you do not wish to connect to a Maritime network you can switch your phone to aeroplane mode whilst travelling.

Information on Roaming with BT Mobile can be found by visiting this help page.

Thanks for the reply however I was trying to avoid switching to flight mode as I want connectivity and most of the time I should be able to get it however we will be in and out of coverage.

If limiting it to EU only roaming then I'll set he mobile network manual to stop the phone from roaming.

Thanks again.

You can also, at least on Android phones, set it to not use data when roaming. Then you only incur charges when making phone calls and when sending/receiving texts
