AIS (1-2- Call, you! Mobile)
AIS Thailand

AIS  (Advanced Info Service Public Company Limited (AIS) ) has the largest 2G/3G network with a 50% customer share. It’s part of the SingTel Corp. that also owns e.g. Optus in Australia and SingTel in Singapore.

Surprisingly, AIS was the last major provider to start 4G/LTE in 2016 on the 1800 and 2100 MHz band (B3, B1), partly marketed as “4.5G” or LTE Advanced. It now covers 80% of the population in 2017: 3G/4G coverage map and is competitive to True and dtac. 5G has started on 2600 MHz (n41). AIS’ prepaid brand is often dubbed 1-2-Call.

The company is controlled by the Intouch Holdings (formerly Shin Corporation), headed by Temasek Holdings, a Singapore government-owned agency. AIS listed on the Stock Exchange of Thailand on 5 November 1991. As of 23 December 2011, Intouch holds 40.45 percent of the shares of the company and Singapore Telecommunications (also majority-held by Temasek) together with Thai Trust Fund and OCBC Nominees holds a 23.32 percent stake.[

Temasek bought the AIS brand through the 2006 acquisition of the Shin Corporation from ousted former Prime Minister Thaksin Shinawatra.

In February 2014, in a conflict between the People’s Democratic Reform Committee (PRDC) and Shinawatra, the PDRC called for a boycott of AIS, wrongly believing it to be owned by the Shinawatra family.
