Need some specific advice re cell phone plans.. Moving to BKK in July, will have phone paid off and unlocked.. Currently with ATT but their customer service is atrocious .. Will be using AIS while living in BKK.. I’ll have eSIM so can simply toggle back and forth between Asian phone # and American phone # when needing two-factor authentication for banks and the like.. that’s the only thing ill need my American phone # for.. My question is: Which American carrier can i switch to (away from ATT) to keep my American phone # active - with the cheapest plan that will work when needing 2FA ? Not interested in Google Voice or similar.. and not interested in paying $90 per month for an “international plan”, only the cheapest plan /carrier active enough to be able to receive 2FA ? Thanks in advance .

Has anyone had any experience with Google Voice. I could never get it to work and I need it. I used AIS for service

This is a anything else question.

I have internet banking with SCB on my phone.

Now I got a new phone and got all the apps installed that I need. When opening the SCB App it wants me to switch from wi-fi to mobile data to verify my phone number.

And here is my problem.

I'm not in Thailand at the moment.

If I put my ais SIM in my phone, switch to 📲 data outside Thailand, would I be able to register into the app or would it just block my account?

On the old phone I can use internet banking outside Thailand without any issues.

Any suggestions?

Thanks
