Travel eSIMs are especially useful as you can acquire them digitally right before you travel, thus eliminating the need for individual SIMs or phones for your travel destination. You can also easily switch phones by registering your new device with your cellular network provider!

How do eSIMs work?

The way an eSIM works is that when you purchase one from a mobile network provider, you are sent a QR code via email, which you can scan and use to install a connection onto your phone. In other words, it is simply the virtual form of a SIM card, which you can easily install on your phone! You do not need to actually go to a mobile communications store and physically purchase a SIM card. In fact, in the wake of the pandemic, this contact-free method of acquiring an eSIM in Thailand is highly attractive to potential travellers!

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

AIS (Advanced Info Service Public Company Limited) is the largest 2G/3G network with a 50% market share in Thailand, and is part of the SingTel Corporation which also owns Optus in Australia and SingTel in Singapore.

Surprisingly, AIS was the last major provider to launch 4G/LTE in 2016 on the 1800 and 2100 MHz bands (B3, B1), partly marketing it as “4.5G” or LTE Advanced. It covered 80% of the population in 2017 and is competitive to both True and dtac. 5G was recently launched on 2600 MHz. AIS’s prepaid package is often dubbed “1-2-Call”.

Company history

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

Temasek bought the AIS brand through the 2006 acquisition of the Shin Corporation from ousted former Prime Minister Thaksin Shinawatra. In February 2014, however, 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!

4G/LTE started in 2014 on 2100 MHz (B1) in Bangkok only and was further expanded in 2015 to Phuket and Pattaya and an additional 40 cities nationwide. In 2015, 4G/LTE was launched in the metro Bangkok area, mostly on the 1800 MHz (B3) frequency, which is more commonly used internationally. In June 2018, DTAC began offering 4G+ on the rare 2300 MHz frequency through a deal with TOT. 5G is intended to be launched on 700 MHz.

They were the first provider in Thailand to bring 4G/LTE on the 2100 MHz (B1) to the country. Their 4G/LTE coverage is, so far, the best in the country, and it rose from 80% to 96% by the end of 2016. In 2015, coverage on the 1800 MHz band (B3) was added for 4G/LTE as well as 850 and 900 MHz (B8) in 2016. 5G was launched in 2020 on 2600 MHz (n41).
