I am in a small village 20km from Fang - 150km N of Chiangmai in an area which by sad experience is very poorly served by copper line services (I have just ditched TT&T for extremely poor service and blatantly dishonest dealings with me - hence my decision to move to a 3G service via the mobile towers.)
I initially had some doubts as the nearest CAT tower is 5km away with no direct line of sight - a hill in-between, but was assured CDMA could handle this. When I voiced these concerns the CAT people (who had acceptable standard of English) volunteered to bring a modem to my house and test it for free. They were there within an hour, installed the software and gave it about a 30 min. run. With the basic level plan (845 baht pm) I immediately had 1.5Mb/s speed. I signed up and subsequently have often had higher speed, up to nearly the 2Mb/s maximum speed of the modem - not brilliant, but quite sufficient for my needs.
In a week of use I have had only one known interruption to the service - less than 5 mins.
The other very positive part of my experience is that they were apparently at pains to show transparency with me - predicting a lower than maximum speed (distance from tower), and alerting me to problems with their accounting system, advising me to keep all my receipts (I already knew about this via this forum so it was nice to hear them admit it up front). That is so SO MUCH in contrast to TT&T who blamed me for everything that went wrong, lied to me continually and had a HOPELESS billing and accounting system.
The free SMS service which comes with the package is just a bonus. The fact that I can use my visa card for the initial cost as well as monthly payments is another. (Cost? 6500B for the modem plus 845B pm, but free for the first 3 months.)
All in all, at this stage I am delighted. I have not experienced the problems with CAT which some others have reported on this forum, but I dare say this might vary between CAT offices and is within the context of my not requiring particularly high speed. For me, a Thailand good news story.
