The Telephone Organization of Thailand (TOT), now known as National Telecom (NT), is a state-owned telecommunications company in Thailand. Here are some key points about TOT's mobile network:

  1. Market Share: TOT has a relatively small market share in the Thai mobile market, with approximately 0.57% of the total market share.

  2. Services: TOT offers various mobile services, including prepaid SIM cards and data plans. These services are designed to provide connectivity to both urban and rural areas.

  3. Infrastructure: TOT has invested in expanding its network, including the installation of public long-distance telephone terminals connected by digital microwave radio links to over 1,800 locations, with plans to expand to about 5,000 more locations.

  4. Private Sector Collaboration: In the early 1990s, TOT collaborated with private sector consortia to expand its network, marking a significant shift towards private sector involvement in telecommunications.

  5. Future Plans: TOT is planning to add six million new phone lines, aiming to reach a total of 12 million lines by the end of the Eighth National Plan (1997-2001). This expansion will require innovative financial and organizational strategies, potentially including privatization.

  6. Customer Experience: Some users have reported mixed experiences with TOT's mobile services, noting issues such as frequent disconnections and variable signal strength.

  7. Competition: The Thai mobile market is dominated by private operators like AIS, DTAC, and TrueMove H, which offer a wide range of services and competitive pricing.

Overall, while TOT plays a significant role in Thailand's telecommunications landscape, its market share and customer experience are overshadowed by the larger private operators.
