To explain the steps-
(1) you have to call Bualuang Phone 1333, on the phone, to make sure your limit is increased to 500,000. This you can do by sticking codes into the handset, you con't need to talk to someone. There's a phone menu "map" at the link below to make this a bit easier.
(2) once your limit is set at 500,000, you can do the transfer online through Bualuang iBanking, just go to add new transfer. IIRC there may be a delay/limit on new 3rd party accounts, I think you have to wait a few days before you can transfer an amount that large. So add them now, and you'll be able to do the actual transfer next week.
