eSIM for Thailand
In Thailand your phone is your taxi meter, your ferry ticket and your translator. Grab and Bolt need data at the pickup point, hotels answer on LINE faster than email, and the Thailand Digital Arrival Card has to be filed online before you land.
A FairSIM eSIM for Thailand runs on AIS or True, the two networks that cover Bangkok, the beach resorts and the main islands, at the wholesale rate. Set it up at home, switch it on when you land at Suvarnabhumi, and skip the airport SIM counter.
That counter matters more than it used to. Since 2025, every Thai SIM must be registered to your passport with a live face scan, in person, and tourist SIMs are capped at 60 days. A foreign travel eSIM is outside those rules.

Coverage in Thailand
- 4G LTE
- 5G
- AISThailand's largest network and the most common host for travel eSIMs. Opensignal's 2025 winner for coverage and 5G speed.
- True (with dtac)Merged with dtac in 2023; claims 93% 5G population coverage. The second travel eSIM host.
Typical speed: About 135 Mbps median download nationally (Ookla, late 2025), among the fastest in Southeast Asia.
Excellent in cities and the main beach resorts, good on highways, weaker in the interior of smaller islands such as Koh Phangan and Koh Lanta, in national parks and in the northern hills.
How much data do you need in Thailand?
It depends on how you travel. Find your trip below, then pick the plan that matches. You can always top up in the app.
Bangkok plus islands, first visit
City temples, then Phuket, Krabi or Samui beaches over ten to fourteen days.
Why data matters: Grab and Bolt for rides, Google Maps, 12Go for ferries and buses, LINE with hotels and tour operators, and the arrival card before you land.

Digital nomad in Chiang Mai or Bangkok
Weeks or months of remote work from cafés and coworking spaces.
Why data matters: Hotspot backup when café Wi-Fi drops mid-call, cloud sync, banking apps. DTV visa holders stay up to 180 days and need a plan that tops up without a counter visit.

How FairSIM works
- 1
Pick a destination and a plan
Choose the country or region and the data you need. The price you see is the price you pay.
- 2
Tap install
On iPhone (iOS 17.4+) the eSIM installs in one tap, no QR code. Do it at home while you still have Wi-Fi.
- 3
Land and connect
Turn on data roaming for the FairSIM line when you arrive. Your plan starts when it first connects.
Connectivity tips for Thailand
File the Thailand Digital Arrival Card online before you fly. If you forget, you will need data or Wi-Fi at the gate.
Order a Grab or Bolt from the airport app pickup zones rather than taking an unmetered taxi.
Ask hotels for their LINE ID. Replies arrive in minutes instead of hours.
On islands, the pier side has 4G and 5G; the far beaches can drop to 3G speeds or nothing. Download maps before the longtail ride.
Monsoon storms knock out island Wi-Fi more often than mobile networks. Cellular is the reliable backup.
Continuing to Vietnam, Malaysia or Singapore? Pick the Asia regional plan so one eSIM crosses the borders with you. Laos and Cambodia are sold as separate plans in the app.
Video-heavy social use burns about 2 GB a day. A 20 GB plan covers two weeks comfortably.
Keep your home SIM on for bank SMS codes, with its data roaming switched off.
Apps you will actually use
- Grab rides, food and airport transfers with a fixed price up front.
- Bolt and inDrive often cheaper than Grab in Bangkok, Phuket and Chiang Mai.
- LINE hotels, tours and drivers use it more than WhatsApp.
- 12Go Asia trains, buses and ferries in one booking.
- Thailand Digital Arrival Card mandatory, submitted online within three days before arrival.
- Google Maps and Google Translate navigation and menus; Thai script is not guessable.
- Agoda and Klook hotels and tours, often cheaper than booking at the desk.
PromptPay QR payments mostly need a Thai bank account. Cards and cash still do the job for visitors.
Can you rely on free Wi-Fi?
Free Wi-Fi is everywhere in hotels, cafés, malls and airports and is decent in cities, but it is slow on the islands and useless between places. Do not count on it for maps or Grab while moving.
Local SIM card or eSIM in Thailand?
AIS and True counters at Suvarnabhumi, Don Mueang, Phuket and Chiang Mai airports sell tourist SIMs from roughly ฿299 to ฿449 for eight days, and 7-Eleven stocks them too. The price is fine; the process is the problem.
Every Thai SIM must be registered to your passport, since August 2025 with a live face scan, and since May 2026 strictly in person with original documents. Foreigners get a maximum of three SIMs per operator and tourist SIMs expire after 60 days with no extension. A FairSIM eSIM is not a Thai SIM, so none of that applies: no counter, no scan, and you top up from the app.

Thailand eSIM questions
Does eSIM work in Thailand?
Yes. Unlocked eSIM phones connect to AIS or True 4G and 5G networks across the country with a travel eSIM.
Which Thai network will I get?
FairSIM plans for Thailand use AIS, the largest and best-covered network, or True. Both cover cities, beaches and the main islands. The app shows the network for each plan.
Do I get 5G in Thailand?
Yes, on a 5G phone in Bangkok, Chiang Mai, Phuket, Pattaya and most provinces. Elsewhere you get fast 4G.
Can I hotspot my laptop?
Most FairSIM plans support Personal Hotspot; check the plan details in the app. Nomads working from cafés should budget an extra 1 to 2 GB a day for it.
When should I install the eSIM?
Install at home on Wi-Fi and enable the line after landing. Validity typically starts on the first connection in Thailand.
Do WhatsApp and LINE calls work?
Yes, over data. The eSIM has no Thai phone number, so keep your home SIM active for SMS codes.
How much data do I need for two weeks in Thailand?
Around 10 GB for maps, Grab, LINE and photos; 20 GB or more if you stream or work remotely.
Is a local SIM better than an eSIM in Thailand?
Local SIMs are cheap but now require in-person passport registration with a face scan and are capped at 60 days. An eSIM skips the queue, needs no passport at a counter, and can be topped up in the app.
What is an eSIM?
A SIM card built into your phone. Instead of a plastic chip, you download a profile. Every iPhone since the XS has one next to the physical SIM slot, so your home number stays put while FairSIM supplies the data.
Is my phone compatible?
FairSIM works with eSIM-compatible, carrier-unlocked iPhones: the XS, XR and everything newer. iOS 17.4 or later unlocks the one-tap install with no QR code. Check the full list on the How it works page.
When should I install my eSIM?
Before you travel, while you still have Wi-Fi. Installing does not start your plan; the validity typically starts when the eSIM first connects to a network at your destination.
Do FairSIM eSIMs come with a phone number?
No. FairSIM eSIMs are data-only by design, which keeps costs low. For calls and texts, your physical SIM stays active so you keep your existing number, and WhatsApp, FaceTime and iMessage work over data.
