How Was Advanced Info Service Founded?
Advanced Info Service was incorporated on April 24, 1986, under the Shinawatra Group. It started as a computer services rental business, then moved into mobile telecom when it won a 20-year BTO concession from TOT in 1990. That shift shaped the AIS company history and set up its AIS evolution in Thailand's underbuilt network market.
How Advanced Info Service Was Founded
Advanced Info Service company founded history starts in 1986 and changed sharply in 1990. The first business was not mobile service, but the telecom opening created the platform for AIS business growth and AIS expansion in mobile telecommunications.
- Founded in 1986
- Founded by the Shinawatra Group, led by Thaksin Shinawatra
- Started with computer services rental
- Shifted after the 1990 TOT BTO cellular concession
In 1990, Advanced Info Service secured a 20-year Build-Transfer-Operate concession from the Telephone Organization of Thailand to run cellular service on 900 MHz analog spectrum. That deal answered a clear market gap in Thailand's telecom network, so the mission, vision, and core values of Advanced Info Service were built around fast network buildout and early mobile access.
Advanced Info Service listed on the Stock Exchange of Thailand in 1991, which gave it public equity to fund network spending and its move from analog to digital systems. That listing became one of the key Advanced Info Service major milestones in the history of AIS telecom in Thailand.
The early model was capital heavy and depended on rapid tower rollout to serve business users first. That is the clearest answer to how did Advanced Info Service company start and how AIS evolved over time.

What Changed Advanced Info Service's Direction Over Time?
Advanced Info Service changed most when it moved from the BTO concession model to licensing in 2012, then again when Gulf Energy Development became a major shareholder in 2021. The 2023 True and DTAC merger raised competition pressure, and the 2025 to 2026 virtual bank push marks its clearest move from telecom into fintech and data-led services.
| Year | Turning Point | Why It Changed the Company |
|---|---|---|
| 2012 | Licensing model shift | Ended the BTO concession setup, let Advanced Info Service own more assets, and improved margins by stopping revenue-share payments to the state. |
| 2021 | Gulf becomes major shareholder | Changed the parent-level strategy and pushed Advanced Info Service toward digital infrastructure, data centers, and green power for towers. |
| 2023 | True and DTAC merger | Created a stronger rival and forced Advanced Info Service to focus more on value-added digital services and cost control. |
| 2025 | Virtual bank venture | Opened a new path into fintech by using a 46 million-strong data base for credit scoring and financial services. |
These moves show how Advanced Info Service evolution shifted from telecom access to digital infrastructure, data use, and financial services. Its Advanced Info Service business model and operating setup now leans more on platform value than basic connectivity.
Licensing Changed the Product Base

Data and Power Became Core Assets

Fintech Became the New Growth Path
The virtual bank plan in 2025 marked a major expansion beyond mobile networks. It uses customer data to move into lending and broader digital finance.

Margin Pressure Forced Change

What Had to Change
