As OJAS said, the Thai banks, seem to be turning away from online banking on computers to more phone banking.
To be honest, IMHO, with all your recent posts about doing away with a mobile phone and doing it all on computer...I really think that to make life easier for yourself, you should do a bit more research on phone models, find one that suits your needs, bite the bullet, and buy one.
As i said. Just my opinion.
