You forgot you had a middle name and you want to gain unlimited access to a foreign country for upto 5 years? I think you should stay home or made to pay double
Just get an unlocked phone and have a dual sim, I live here but have my thai sim and my uk sim in the same phone, or just have an esim, I use AIS over here, 1 year unlimited internet for 2500 baht 5mb speeds, my uk sim is giff gaff pay as you go
where did I say it's not changing? I think you have a serious attitude problem, the fact of the matter is that like it or not if you landed in Thailand or anywhere else in SE Asia for that matter today, you would cope alot easier using cash than if you relied solely upon card/digital payments, will this change in the future, of course it will but for now, its a cash society, im correct on that, like it or not
