Yeah can real only top via Thai bank account or cash in 7-11 or affiliated shops i.e True mobile I think...
So I sometimes send it to a friend with This bank account and then they fire it across...
Plus limited to 30 "PERSONAL QR" Scan payments per month....
Look into Moreta app for scan payments very useful & handy as can link to Wise or Revoult or other banks etc & supposedly meant to be able to scan personal QR codes by January and can also use in other S.E Asian countries too...
