There is a long list of Internet service providers in Thailand, especially in major cities such as Bangkok. If going to a cyber cafe every time you need Internet services is not something you enjoy, you can get an Internet package that you can pay for on a monthly basis. Basically, there are three major players in this highly crowded field: 3BB, TOT, and True.
There are about a dozen other minor Internet service providers, some of which actually offer quite good quality services, even though their coverage might only be in some specific areas such as the cities.
True offers both wired and wireless Internet connections to Thai residents. The more popular package, True Internet, a wired Internet connection option, is available through cable modem, leased line, ADSL2+ among other wired Internet technologies. This connectivity option also offers speeds of between 6 Mb/s and 100 Mb/s.
The wireless Internet connectivity option offers significantly inferior connection speeds of up to 256 Kbt/s, and is available through GPRS and EDGE. However, the company also offers TrueMove-H, a wireless Internet option that can reach up to speeds of 42 Mb/s subject to the wireless connection technology used.
3BB’s coverage is less widespread than True’s coverage. However, users can access Internet services from this provider using wired technology such as ADSL2+, VDSL2, Leased Line, and even FTTH. You can also enjoy speeds of between 10 Mb/s to 100 Mb/s.
TOT is one of the most popular Internet service providers in Thailand. The wired Internet services, available through ADSL2+, Leased Line, and FTTH, can reach speeds of between 6 Mb/s and 15 Mb/s. However, with the FTTH package, users in some areas can enjoy connection speeds of up to 30 Mb/s.
TOT also offers a great wireless connectivity alternative through UMTS/HSDPA/HSPA/HSPA+ 3.9G, and Wi-Fi. Users of this option can enjoy speeds of up to 42 Mb/s. However, wireless connectivity is only found in Bangkok and its outskirts at 2100 MHz band.
CAT offers wired Internet connection services to Thais using ADSL, G.shdsl/SDSL, Cable, Lease Line, and FTTH. The connection speeds are also quite impressive, since the speeds range from 4 Mb/s to 1 Gb/s, making this option appropriate for both individual users and corporations.
KSC Internet offers dial-up, ADSL, and Leased Line Internet connection options. Although this company is owned by True Corporation it offers a unique Internet connection service targeted at the high-end market. KSC was the first commercial Internet service provider in Thailand.
CS Loxinfo focuses on providing broadband Internet through wired technologies such as Fiber, MPLS, Leased Line and ADSL. Connection speeds can reach up to 1 Gb/s, with the higher speeds aimed at corporate entities. The service is mainly concentrated in Bangkok and surrounding areas.
There is a broad choice of Internet service providers in Thailand. However, the three major players in the industry based on coverage are 3BB, True, and TOT. There are also other great Internet service providers that can offer excellent Internet services, but using such alternatives will depend on where you live in Thailand, since most areas might not have service coverage. However, you should consider all these options since there might be substantial price differences despite similarity in connection speeds.
