my 2 sons were born in Thailand i registered them both in the uk from Thailand and got British birth certificates so why can't JF James do the opposite way
i did'nt get locked out on my kisikorn account as i swapped phones in Thailand i was just stating you have to go to your new phones internet not wifi turn it off, i was locked out off my bangkok account through the covid period and was saying after 3yrs when i returned it all got sorted by phone in Thailand.so dont be worried if you get locked out its simple to sort when you come Thailand next.
Im with kisikorn bank and both my wife and me had to go to data internet to set up our app on new phones.give your data internet a try if it does'nt work ya can sort it when next ya come Thailand.i had once simular with bangkok bank got locked out of sign in to account but got here and sorted it all over the phone with service care
