Where the signal holds

Airport Rail Link
Rail from Level B1
The station sits on Level B1 of the main terminal, and the airport gives its hours as 05:30 to 24:00.
4G and 5G
Thailand's three networks
AIS keeps 5G pages for consumers, True describes a 5G and 4G network, and NT sells services on its 5G network.
Data roaming on
Your eSIM
The eSIM runs on a Thai network and shows that network's name in your phone's settings. Turn data roaming on for the eSIM line.

PayingThe currency is the Thai baht (THB), divided into 100 satang. Banks, ATMs and exchange counters are among the airport's services, and the Bank of Thailand publishes the exchange rates it uses.

Arrival, step by step (Bangkok Suvarnabhumi)

Install the eSIM at home on Wi-Fi before you fly, and keep the line switched off. After landing, turn off airplane mode, switch the eSIM line on, choose it for mobile data and turn on data roaming for that line only. Nothing needs collecting at a counter: the line is already in the phone. If it does not connect, restart the phone once, then work through the checks in the help pages one by one.

Questions

Can I get a Bangkok airport SIM card on arrival?

A SIM card is bought in person, so it means a stop after landing. The eSIM is installed at home before the flight and switched on when you land, so nothing waits at the airport.

How do I get from Suvarnabhumi to Don Mueang airport?

The free shuttle leaves from Level 2, Gate 3, every 30 minutes from 05:00 to 24:00; it carries travellers connecting between flights at the two airports.
