No. of users in thailand. Thai people don't spend
much time at home or with PCs
Prices for DSL varies depand on the speed, you
pay more, and get faster connections, they also
have cable internet that comes from UBC provider:

I know tens of 3 to 4stars daily serviced apartment
with in-room DSL with speed of 1MBPS for 60$/monthe.
You can stay for a week for a daily rate of 30$/day.
Monthly will cost you 20$ a day for the room.
I have been trading full time in thailand for 3 monthes
and been using Xoomtrade brokerage direx platinum
platform which requires DSL connection to avoid drop
off.
I never had any connection problem. Believe me the
speed was even faster than my home DSL in Dubai
where is my first home.
I read somewhere i guess Roberk were using Dial up
connection and not DSL, so i am giving you first-hand
experiance for Active trading from Bangkok.
