Apple Watch doesn’t support roaming even on officially supported providers.

I’m on EE (T-Mobile and Orange consortium in the UK) which means when I roam in the EU it connects to T-Mobile and Orange which support the watch in their local countries but the roaming doesn’t work.

Also with LTE there is no sync with the phone the sync won’t work unless you are connected to WiFi it doesn’t use BT afaik it uses airdrop.

The airdrop is also anecdotally supported by the fact that my company has disabled airdrop recently when they rolled out DEP to all work issued phones since then I can’t sync the watch with my company phone.
