, check around for UOB bank Thailand., Rather hopping branches to banks., Applicable and can open anywhere ,No age and visa requirements. The bank have routine savings account with debit card , and all internet and application features. And is especially for foreigners. 50k initial deposit and your residence proof rent/owned alongwith passport. And on the spot you get debit card and bank book. go out and withdraw money. Required balance is just 5k.
FYI, I got it done at bangkok on 2 month SETV back in 2017.It's worth if you got in your area. Back then was only bank having this feature. If not start from Bangkok bank etc etc
