Sorry an oversight. Yes tried all 3 true, AIS, and dtac. Visited at least 2 large stores for each b/c the level of English and technical assistance knowledge/willingness to help varied a lot. Also had concierge from hotel call them and one said no agreement one said didn't work with oneplus, etc but the answers seems random. All referred to manufacturer but of course there is no AIS shop in Bangkok (or the US except maybe NY? but all tech support is by email.
If the same model weren't sold in Thailand and working I wouldn't be so surprised but I'm thinking it has to be a missing band (even tho the specs look like there isn't)
