SIM cards at Suvarnabhumi Airport, what to expect
After clearing immigration and baggage claim at Suvarnabhumi, you'll see SIM card counters from AIS, TrueMove H, and DTAC spread across the arrivals hall. Counters are generally open 24 hours and staff speak English. Passport registration is required at the point of purchase and most counters inside the baggage claim area are cash only, so you'll need Thai baht before you can buy.
Tourist SIM packages at the airport are more expensive than what you'd pay at a phone store or shopping mall in central Bangkok. You're paying a premium for the convenience of buying on arrival, and still waiting in a queue to do it.
Free WiFi is available throughout Suvarnabhumi Airport if you need to get online while you sort transport or accommodation on arrival.
For most travellers, activating an eSIM before departure is the simpler and cheaper option.

When to activate your Thailand eSIM
Install the eSIM before you leave home while you still have a stable WiFi connection. Scan the QR code from your order confirmation and follow the prompts in your phone settings. The process takes about two minutes.
Keep the eSIM turned off until you land so your data validity period doesn't start early. When your plane touches down at Suvarnabhumi, switch to the eSIM line in your settings, enable data roaming, and you're connected before you reach immigration. By the time you're booking a Grab or heading to the Airport Rail Link, you're already online.

Network coverage in Bangkok and across Thailand
The Ezy eSIM for Thailand connects to AIS 5G and TrueMove H 5G, the two largest and most reliable networks in the country. Both networks provide excellent coverage across Bangkok including the city centre, BTS and MRT lines, and all major tourist areas.
Coverage extends strongly across the rest of Thailand including Chiang Mai, Phuket, Koh Samui, Krabi, and Pattaya. For island destinations, coverage is reliable on the main tourist islands and drops off only in very remote coastal areas.
Getting from Suvarnabhumi Airport into Bangkok
Having your eSIM active before you leave arrivals makes navigating onward transport straightforward. Your main options are:
Airport Rail Link. The fastest and most affordable option into central Bangkok. The express service reaches Phaya Thai Station in around 30 minutes. Tickets are purchased at the station on the basement level of the airport.
Grab or Bolt. Both ride-hailing apps work well in Bangkok and are significantly cheaper than metered taxis for most routes. You can only use them from the designated pick up zones outside the terminal. Having your eSIM active means you can book before you even exit arrivals.
Metered taxi. Available from the official taxi rank on the first floor of the arrivals terminal. Insist on the meter being used and be prepared for traffic, especially during peak hours.
Private transfer. Many hotels offer airport pickup. Message your accommodation to confirm arrangements the moment you land.
