Thailand’s Mobile Market as of Q1 2021
Despite the weak economy and a third wave of Covid-19 infections, the mobile market in Thailand managed to bounce back in Q1 2021 with a strong subscriber growth of +2.2 million compared to the previous quarter loss of -2.3 million.
The competition between the Big 3 (AIS, TrueMove and DTAC), was stable with unlimited data packages and device bundling campaigns, as key attractions amid continued impact from the COVID-19 outbreak.
Although the Big 3 attempted to uplift average revenue per user (ARPU), by introducing larger unlimited package, the new acquisition remained concentrated on smaller packages, as consumers affected by the sluggish economy were seeking value-for-money.
In April, a new wave of Covid-19 re-emerged and further strained tension on the economy. However, mobile revenue recovered QoQ due to strong subscriber acquisition, as well as demand driven by government stimulus packages into the market. Combined, AIS, TrueMove and DTAC, managed to gain +2,205,000 subscribers year on year (YoY) and +2,140,300 quarter on quarter (QoQ).
The two state enterprise telecom network operators, CAT Telecom and TOT was officially merged into a new entity; National Telecom (NT) Plc., which also managed to grow its subscribers from a combined (CAT + TOT) 3,3 million EOY 2020 to 3,4 million in Q1 2021.
No new MVNO licenses or IoT/M2M licenses was awarded in the first quarter of 2021 and the telecom regulator, The National Broadcasting and Telecommunications Commission (NBTC), continued to stay in a decision-making vacuum due to a long delay in the establishment of its new board.

A HIGHLY CONCENTRATED MARKET - LACKING COMPETITION
The Herfindahl-Hirschman Index (HHI) is a common measure of market concentration and is used to determine market competitiveness.
A market with an HHI of less than 1,500 is considered to be a competitive marketplace, an HHI of 1,500 to 2,500 to be a moderately concentrated marketplace, and an HHI of 2,500 or greater to be a highly concentrated marketplace.
The Herfindahl-Hirschman Index (HHI) in the Thai mobile market in Q1 2021 is 3,409 – showing a highly concentrated market lacking competition.
