What Happens When You Land in Thailand
- 1
Install your eSIM before your trip
Buy an LTE.app Thailand eSIM and install it on Wi-Fi at home. Takes 2–3 minutes via QR code. Your home SIM stays active and untouched.
- 2
Land at Suvarnabhumi Airport
After your flight, switch off airplane mode. Go to Settings and enable your LTE.app eSIM line.
- 3
Connect to AIS, True Move H (DTAC-True merger)
Your phone automatically connects to Thailand's LTE network. Bangkok has excellent LTE coverage. Beach destinations (Phuket, Koh Samui, Pattaya) are well covered. Remote islands and northern mountain areas may have limited signal, especially Koh Tao and deeper parts of Chiang Rai province.

Maps, messaging, and apps work instantly
Navigation, translation, ride-hailing, and messaging apps all work from the moment you exit the arrivals hall — no queuing, no SIM card swap.
Will my phone work in Thailand?
Yes. Thailand's LTE bands are universally supported by modern smartphones.
Thailand uses LTE bands 1, 3, and 28 — the same bands used across Southeast Asia and Europe. Any phone bought in the last 5 years will work. 5G is available in central Bangkok on AIS and True Move. If you're heading to remote areas like Koh Tao or the Golden Triangle, choose a plan on AIS (the strongest rural carrier).
How much does roaming cost in Thailand?
Roaming with your home carrier in Thailand is significantly more expensive than a local eSIM.
US carrier roaming in Thailand can cost $10–15/day. EU carriers often charge €0.02–0.10/MB outside the EU — a 1 GB video call can cost €20–100.
Roaming vs local SIM vs eSIM in Thailand
Local SIM cards in Thailand are extremely cheap — among the best value in Asia. An eSIM is even simpler.
AIS tourist SIM cards at Suvarnabhumi Airport cost $8–15 for 15–30 GB. The trade-off is a 20-minute airport queue and passport registration. An LTE.app eSIM for Thailand on AIS or True Move is comparable in price with zero queuing and your home SIM stays active.
Best internet option for Thailand tourists
If you want to avoid airport queuing and keep your home number active, an eSIM is the best option.
Thailand's local SIM price advantage is smaller than it used to be. LTE.app's Thailand plans are competitively priced against airport SIM card booths. The key benefit: you can activate your eSIM before landing, so Google Maps and messaging work the moment you step off the plane at Suvarnabhumi.
LTE coverage and networks in Thailand
Thailand primarily uses LTE bands 1, 3, and 28. AIS 4G+ covers 97% of the population. True Move and DTAC (now merged as NTPLC) also provide strong national coverage.
Bangkok has excellent LTE coverage. Beach destinations (Phuket, Koh Samui, Pattaya) are well covered. Remote islands and northern mountain areas may have limited signal, especially Koh Tao and deeper parts of Chiang Rai province.
Connectivity tips for Thailand travelers
- →Grab (ride-hailing) is essential in Thailand — you need data to book rides, especially in Bangkok.
- →Google Maps works excellently in Bangkok but save offline maps for more remote island destinations.
- →Many markets and street vendors in Chiang Mai accept QR payments (PromptPay) — connectivity makes this seamless.
