Yes I checked the apn settings (per the store altho one salesman didn't even know what I was talking about but I looked for the apn myself and it looked correct. Yes the whole idea that I have a good 4g signal but data doesn't work is astounding. Haven't tried any voice call cause I never use that but the phone says carrier is whatever sim is there and strong 4 bar signal - so I'm stumped.
It's very much like a problem I had in Vietnam years ago where the router for wifi used a band that wasn't on my phone but when I got the owner to switch the router setting it worked - maybe a different problem this time but that is what sticks in my mind.
I do know that in the 3 hours I spent with AIS different people checked the apn and reset btwn 2 different (but similiar apns) multiple times and that didn't fix it
I really wish I could find someone who has purchased a US phone and then was able to use it here but none of my searches have found that. I'll keep looking.
The problem I had in the US wasn't data related and I've always tried the Thai sims in sim 1 just in case (with no sim in the other slot to keep things simple)
Wish I could find somewhere that doesn't just try for 3 minutes then tell me it has to be oneplus issue and to call them

Something is wrong with the way you have it configured, but if it's not APN then I don't know what it could be...
Oh and just to complicate things even more - sms from AIS (only) showed up on my phone but one message showed up on whatsapp shortly after my first visit to the AIS store (when I thought it was fixed- but I couldn't reply) and when I went back to the store an hour later they couldn't explain or get it to work. Also had another shop check that my service was configured correctly and it did show that I had the use of the data I had purchased.
