# Thailand eSIM & Apps to Install Before You Land in 2026

In August 2026 alone, our archive of r/Thailand, r/Bangkok and r/ThailandTourism logged 413 comments across 28 threads asking which SIM to buy and which apps to run — plus separate clusters on airport SIM vs. eSIM (129 comments, 7 threads) and Grab vs. Bolt (70 comments, 5 threads). This page works through both questions with the carriers' own 2026 prices, not a recycled app-store listicle.

Last verified: 4 September 2026.

## Install before you land

**Apps to install before arriving in Thailand: what each is for, cost, and a note**

| App | What for | Free / paid | Note |
| --- | --- | --- | --- |
| AIS or True eSIM | Data plus a Thai phone number | Paid, from ฿449 | Buy online before you fly or at the airport counter — the published price is the same either way. |
| Grab | Rides, food delivery, courier, in-app payment | Free to install | Add a card before landing; cash still works with most drivers. |
| Bolt | Rides, frequently the cheaper of the two apps | Free to install | Its Thai operating licence was under Department of Land Transport review through 2026 — keep Grab installed too. |
| LINE | Messaging; the account most Thai businesses actually use | Free | Restaurants, landlords and spas commonly hand you a LINE ID, not a phone number. |
| Google Maps | Walking, driving and BTS/MRT/Airport Rail Link directions | Free | Routes Bangkok's rail transfers and timings better than Apple Maps. |
| Google Translate | Camera translation of Thai menus, signs and forms | Free | Download the offline Thai language pack before you land, in case signal is patchy on arrival. |
| Wise or Revolut | Card spending and ATM withdrawals at a fairer exchange rate | Free to install; card fees vary | Doesn't waive Thailand's own flat ATM fee — see the money guide for the current figure. |
| Klook or Agoda | Booking activities, transfers and hotels ahead of arrival | Free | Skip-the-line tickets and hotel confirmations land in your inbox before you touch down. |
| Air4Thai or IQAir AirVisual | PM2.5 air-quality readings by district | Free | The two disagree on Bangkok's numbers on smoggy days — worth having both installed. |
| MuvMi | Electric tuk-tuk hailing for short Bangkok hops | Free to install, pay per ride | Fixed fares across 7 service zones — no haggling over the price before you get in. |

## eSIM vs. airport SIM vs. 7-Eleven

AIS (product name: LUCKY TOURIST SIM) publishes one price list for its tourist SIM whether you buy it at an AIS shop, an airport counter or as an eSIM through ais.th — as of September 2026 that was ฿499 for 8 days, ฿699 for 15 days, ฿1,199 for 30 days and ฿1,599 for 60 days, all unlimited data at max speed, free calls within the AIS network and a ฿100 bonus credit for calls to other networks. A 1-day, 1GB SIM capped at 10 Mbps is also sold for ฿49.

True/dtac (True Corporation, formed by True and dtac's 2023 merger, still sells both brands separately) confirms its 8-day Thailand Tourist INFINITE SIM at ฿449 on true.th, with free local calls up to 15 minutes per call. The 15-day (~฿699) and 30-day (~฿1,199) tiers weren't itemized on the page we checked — those figures come from 2026 SIM-comparison sites rather than true.th directly, so treat them as indicative until you see the checkout price. True's own tourist-SIM page lists Airalo, eTravelSim, Mobimatter and several other resellers as official partner channels.

Third-party eSIMs (Airalo, Holafly and similar) run on the True network in Thailand and cost more per day of data than AIS or True's own tourist SIM — Airalo's 30-day unlimited plan was ฿1,659.50 against True's roughly ฿1,199 — but they install before you fly with no passport step, work while you're still in the air, and stay usable on a short layover. The trade-off: they're data-only, so you land without a Thai phone number for calls, food-delivery verification or two-factor SMS codes.

7-Eleven sells SIMs at the same price as the carrier's own tourist plan, but reports from travelers in August 2026 found most branches stock the physical SIM only, not an eSIM QR code — plan on a phone with a physical SIM tray if 7-Eleven is your backup.

Every option above needs a passport at registration — under NBTC rules, AIS and True both cap foreign registrations at 3 SIMs per brand and limit a tourist SIM's validity to 60 days with no top-up extension past expiry; continuing past that means re-verifying identity by SMS or in person.

**Comparison of Thailand connectivity options: data, price, calls, passport requirement and where to buy**

| Option | Data | Price (Sept 2026) | Calls | Passport | Where |
| --- | --- | --- | --- | --- | --- |
| AIS Tourist SIM/eSIM (official) | Unlimited, max speed | ฿499 (8d) · ฿699 (15d) · ฿1,199 (30d) · ฿1,599 (60d) | Free within AIS + ฿100 bonus credit for other networks | Yes — re-verify by SMS or in person after 60 days | AIS shops, airport counters, ais.th (eSIM) |
| True/dtac Tourist INFINITE SIM (official) | Unlimited, max speed | ฿449 (8d) · ~฿699 (15d) · ~฿1,199 (30d) | Free local calls up to 15 min/call, then ฿5/min | Yes — max 3 SIMs per person per brand | True/dtac shops, 24-hr airport counters, true.th, listed resellers |
| Airalo eSIM (True network) | Unlimited, data-only | ฿322 (3d) to ฿1,659.50 (30d) | None — no Thai phone number | No — email verification only | airalo.com, installed before you fly |
| Holafly eSIM (True network) | Unlimited, data-only | From about $3.90/day (approximate — confirm at checkout) | None — no Thai phone number | No — email verification only | esim.holafly.com, installed before you fly |
| 7-Eleven | Physical SIM, stock varies by branch | Same published price as the carrier's own tourist SIM | Depends on the SIM sold | Yes | Convenience stores nationwide — eSIM rarely stocked in-store as of August 2026 traveler reports |

Which to pick: for a one-week trip, AIS or True's own 8-day tourist SIM (฿449–499) beats any third-party eSIM on price if you don't mind registering with a passport on arrival — or buy the same carrier's eSIM online first if you want to land already connected. For a month, AIS or True's 30-day plan again undercuts Airalo or Holafly's 30-day price. For a longer stay, remember the 60-day cap on any tourist SIM: past that point you re-register with a passport rather than just topping up, and a Thai number (not a data-only eSIM) is what most local apps — banking, food delivery, two-factor codes — expect to see.

## Money, transport, food and translation

Money. A Wise or Revolut card gets you a fairer exchange rate than a home bank card, but it doesn't waive Thailand's own flat ATM fee — commonly ฿220 per withdrawal, with some machines now charging up to ฿350. Fewer, larger withdrawals cost less overall than topping up daily; the full breakdown, plus where to exchange cash in Bangkok, is on the [money guide](https://bestofthailand.org/currency).

Transport. Install both Grab and Bolt — Bolt is reported cheaper more often than not, but Grab has the wider driver network outside Bangkok and doubles as a food-delivery app. Google Maps outroutes Apple Maps on BTS/MRT transfers and timings. Thailand's 20-baht flat rail fare runs through the Tang Rat app but requires a Thai national ID, so it doesn't apply to visitors — tourists still tap a Rabbit card or contactless bank card at standard distance-based fares. MuvMi's electric tuk-tuks cover short hops across 7 fixed Bangkok zones at a set fare, no negotiating. The full BTS/MRT/taxi breakdown is on the [getting-around guide](https://bestofthailand.org/getting-around), and the airport-to-city leg specifically is on the [airport guide](https://bestofthailand.org/airport).

Food delivery. Grab Food and LINE MAN (LINE MAN Wongnai) split close to 90% of Thailand's food-delivery market between them, with ShopeeFood a distant third at roughly 10%. Foodpanda shut down its Thailand operation on 23 May 2025 after 13 years of losses — don't install it expecting it to work.

Translation. Google Translate's camera mode reads Thai script on menus, signs and forms in real time. Download the offline Thai language pack before you land — it works without a data connection once installed.

## Before you fly: the arrival card and air quality

Thailand Digital Arrival Card (TDAC). Mandatory for every non-Thai national since 1 May 2025, replacing the paper TM6. Fill it in online at tdac.immigration.go.th within 3 days (72 hours) of arrival — not earlier, and not an app you install ahead of time. Full visa and entry-rule detail, including what happens if you overstay, is on the [visa checker](https://bestofthailand.org/visa).

Air quality. Air4Thai (the Pollution Control Department's own app) and IQAir AirVisual both report Bangkok's PM2.5 levels, and they don't always agree — Air4Thai has shown noticeably lower readings than AirVisual on the same smoggy days, enough that it's drawn comment from Thai residents comparing the two. Worth having both installed for the November–March haze season; our own city-by-city PM2.5 tracking is on the [air quality page](https://bestofthailand.org/air-quality).

## Frequently asked questions

**Do I need to buy a Thailand SIM card before I land?**

No. AIS and True both sell tourist eSIMs directly through their own sites (ais.th, true.th) at the same price as their airport-counter SIM, so you can install and activate before boarding. AIS's 8-day unlimited-data eSIM was ฿499 and True's equivalent ฿449 as of September 2026; both ask for a passport number at checkout.

**Is Bolt actually cheaper than Grab in Thailand?**

Riders on r/Thailand, r/Bangkok and r/ThailandTourism say so more often than not: in 34 comments directly comparing the two apps, several independently called Bolt cheaper and none said the reverse — though neither app publishes a rate card, so the gap moves with the trip and the surge multiplier. One caution for late 2026: Bolt's Thai operating certificate lapsed on 31 May 2026 during a Department of Land Transport review of driver violations and was running on a short extension as of this page's last check, so keep Grab installed as a fallback.

**Do foreigners have to register a Thai SIM card with their passport?**

Yes. Under NBTC rules, both AIS and True require a passport number to activate a tourist SIM or eSIM, cap foreign registrations at 3 SIMs per brand, and limit tourist-SIM validity to 60 days with no top-up extension past expiry. To keep the same number after that, you re-verify identity — AIS does it by SMS (passport number to 4444161) or in person at any AIS Shop; True requires a shop visit or a call to 1242.

**What is the Thailand Digital Arrival Card and when do I fill it in?**

The TDAC (tdac.immigration.go.th, free) has been mandatory for every non-Thai national entering Thailand since 1 May 2025, replacing the old paper TM6. Submit it within 3 days (72 hours) of your arrival, not earlier — the form and QR code you get back are what immigration checks on landing. The full visa and entry-rule breakdown is on our visa checker.

**Does Foodpanda still deliver in Thailand?**

No. Foodpanda shut down its Thailand operation on 23 May 2025 after 13 years without turning a profit. Grab Food and LINE MAN (LINE MAN Wongnai) now split close to 90% of the food-delivery market between them, with ShopeeFood a distant third at roughly 10% since Foodpanda's exit — install one of those instead.

**Should I use Google Maps or Apple Maps for the BTS and MRT?**

Google Maps. It routes Bangkok's BTS, MRT and Airport Rail Link with line-by-line transfers, timings and delay alerts; Apple Maps marks the stations but doesn't build the same transit routes. On fares: Thailand's 20-baht flat rail fare, registered through the Tang Rat app, requires a Thai national ID and doesn't extend to tourists — you'll still pay the standard distance-based BTS/MRT fare on a Rabbit card or contactless bank card.

## Sources and verification

Carrier prices and terms checked directly against ais.th (SIM & Plans for Tourist) and true.th (Tourist SIM and eSIM for Traveller in Thailand) on 4 September 2026; eSIM prices from airalo.com's own Thailand plan page (same date). Holafly's per-day pricing is drawn from third-party 2026 eSIM comparison sites rather than a clean price table pulled from esim.holafly.com directly — confirm the exact figure at checkout. TDAC rules are cross-checked against the U.S. Embassy Bangkok's own May 2025 notice and Thailand's immigration site. NBTC SIM-registration rules (passport, 3-SIM cap, 60-day validity) come from AIS's and True's own tourist-SIM terms, not a secondhand summary. Reddit figures are pulled from our own archive of r/Thailand, r/Bangkok and r/ThailandTourism — an English-language, self-selected sample used as a demand and sentiment signal, not a controlled survey.
