BKT card, BKK Plus *

All provided through the same access numbers (1-800-613-7238, 1-800-605-7506)

I bought these cards several times because I did not know they were providing service using the same network. The price of the cards are reasonable, but the quality is awful. I often hear loud glitches during the calls and I hear crosswire interference (other people's conversations). I believe that a lot of people use their services, so I it hard to connect to the access number and to connect to Thailand. I can barely get through to Thailand and have to put up with busy signals. They really need to increase their system capacity.
