I moved here in 2003 and used IPstar then from Loxinfo when it was on the Thaicom satelitte, I then moved to TOT when they offered it in 2005 and a dedicated satellite was launched.

Cost 10K a month then but allowed me to run online business and open internet cafe business in Issan.
Shooting games were out as the ping is slow but speeds then were good
I presume Tot still offer it, youd need to ask at a local office
