This is an old post, but I would like to add my '2 Bobs worth.' I have been using 3BB in Sattahip area of Chonburi for about 5 years, and can honestly say I swear by them. When I first used them in Pattaya 2009/2010 I think they had just started in Pattaya area, they were Bad with a capital B, but now AI with me. I recently asked them if I could get my present Fiber Optic package transferred to my intended new location of Lam Plai Mat district, I did not have a Street address as unnamed Road and farming land, so I gave them the GPS coordinates, 2-3 days later they got back to me and said YES you can transfer existing Fiber Optic account to that address, but would cost about 4,000 Baht, to issue new modem (about 1,500 each) and install new cable to the intended property, including paperwork.
On the original post he does a speed test and I noticed he was using Singapore as a test point. must use a test point within your country to get an accurate reading preferable within same province.
I have had many problem with Rats eating Fiber Optic Cable within the Condo building, and squirrels eating cable in the 500 metre drive-way to my Condo building. 3BB were coming every 3 or 4 weeks to repair cable. until I impressed on them to save them money and my internet time, we must upgrade or bury cable. So a new 'anti squirrel' cable was install in the drive way, and internally Fiber Optic cable was place in a Poly Tube. No official cost to me, but big job, over 2 days so gave workers (3) 2,000 in tips. Calling the 1530 3BB call centre number I never had to wait in excess of 5 minutes and many times a lot less. Only problem I had was with the very heavy accented Thai girls in missing some of what they said. Now many weeks since there last visit, after getting Red Light in my Fiber Optic Modem. Did you know when the Fiber Optic cable is broken, there is a little red light in the part of the cable that is still live.
