Telephone Services

Telephone services

Thailand's telecommunications services are at an international standard, especially in urban areas such as Bangkok. There is an abundance of fixed lines for offices and residences. Thailand is rapidly developing an IT industry. Fixed telephone lines, mobile telephones, dial-up Internet and ADSL broadband are all available.

In Thailand, there is only one fixed-line operator that is the Telephone Organization of Thailand (TOT). They can install phones in a timely fashion; usually within a matter of days. Local calls are not timed and carry a fixed charge of 3 baht per call.
