T-Mobile iPhone 7, 4G LTE issues in UK

Hi all. Recently upgraded from my iPhone 6S to the 7.

When roaming in the UK, I can only access 3G data - no 4G / LTE at all, on any network.

Have applied all updates, restarted phone, etc.

My T-mobile package includes unlimited domestic data, and a high speed international data pass for Europe (barely touched due to being stuck on 3G).

I travel from the US to the UK every few months, and previously have always been able to access the fastest network speeds available (assuming I had a valid t-mobile international high speed data pass!), but this latest iPhone won't connect to anything above 3G.

All options in Cellular are correct (LTE enabled, data roaming).

My wife's also got a new iPhone7, also on T-Mobile US, and hers is exactly the same.

Anyone have any idea what has changed? Clearly there's something different about the 7 (or the latest OS) and it's a little frustrating 🙂

What did T-Mobile say when you contacted them about their cellular data issue?
