I guess this is a very specific question, but I thought I'd give it a try nonetheless!

I'm using my Jolla on the three UK network (three.co.uk) and it works perfectly. However, when roaming abroad (Belgium and Ireland), it won't let me use data. Phone calls work fine, but I get no joy with data in spite of trying on 2G, 3G and 4G. I checked the data roaming settings under Mobile network, and there's nothing there that looks wrong. Three customer services - perhaps unsurprisingly - weren't able to help given it's not a supported phone, but they were able to confirm that there are no settings on my account that should have prevented it working.

So, my question is whether anyone else has any experience with this, or any insight into what the problem might be.
