EU roaming - St. Martin

Hi, just wanted to check if there is a more recent update on this - I can see a thread from 2023 but the information on O2 website seems to be different now.

We are travelling to St Martin/Sint Maarten - an island in the Caribbean, and I'm trying to understand if I can use my EU roaming data as part of that. For context, the island is split in 2 - a French side (it is fully part of France and is therefore part of the EU), and a Dutch side (not part of the EU).

The main question is - am I able to use my data as part of EU roaming, if I stick to the French networks on the island? The information on the O2 site suggests not, which seems unusual unless it is an exception to EU roaming?

Otherwise, I assume the spend cap will limit any data usage outside of my plan anyway? Thanks!

According to

https://www.o2.co.uk/international/using-your-phone-abroad

The answer is no, which I guess you have seen

There are a couple of the Carribbean Isle where EU roaming doesn't apply

As we left the EU all such roaming is seen as a concession not a legal right

@Jamie2391

You will need to pay to use your phone in both parts of the Island, as neither are included in the EU roaming rules

I would recommend looking here https://www.o2.co.uk/international/using-your-phone-abroad

But just from the screenshots below, its expensive

Thank you both for the answers, much appreciated! Will get a local sim out there in that case.

There is still a conflict on the O2 site.

If you type it into the destination guide, Saint Martin (French) is listed as covered under Europe. https://www.o2.co.uk/international/using-your-phone-abroad

However, it is also listed under Zone 3 here https://www.o2.co.uk/international/data-roaming-bolt-ons

So there is still a conflict. Which is correct?

@Ray_Cheshire

The French part, Saint Martin is covered in EU roaming, the Dutch part, Sint Maarten isn't, so manually selecting the correct network is crucial in avoiding fees.

@Dave-O2 can you leave a note to have Saint Martin removed from zone 3 before you go?
