It’s not at Seacon Square. You have to go immigration divison at ChangWattana building in Goverment complex like everyone else and wait and wait, and it can’t be done online first time
OMG 😨.. Please don’t ask Facebook groups this .. plenty of good free tools like Google, chatgpt etc. The short answer: Yes you can.. But also very different experience from Bank to Bank. Suggest to Bangkok Bank and go to your embassy for the documents they require .. dress nicely, ask them to call the an english speaking customer service .. often bad english is reason for objection dress nicely and keep ur cool !
Approx same or cheaper than UK.. (Vat is 7%) You find in MBK (downtown), Fortune Town (also downtown close to Makkasan train station opposite Central Rama 9) other shopping malls plenty of 2nd hand phones of your liking. Fortune town is my favourite in terms of trust.
