These are our 6 picks. See every Thailand plan from every provider, sorted by price per GB.All Thailand plans →What we found in Thailand
Every one of our picks with a confirmed Thai host network names AIS, and Nomad is the only one that lists AIS, True and dtac.
We compared 6 travel eSIMs for Thailand on the price of a 30-day plan at the size most people buy. Right now Nomad is our top pick at $10, and Nomad works out cheapest per gigabyte ($0.30/GB). Prices update daily from each provider, so the table above always shows the current order.
Thailand's mobile networks are AIS, TrueMove H and dtac. In Opensignal's Thailand report for August 2026 (data from April to June 2026), dtac and True took Best Network, winning reliability and download speed outright. dtac had the fastest average download speed at 41.1 Mbps, just ahead of AIS on 40.8 Mbps and TrueMove H on 38.7 Mbps, while AIS led on consistent quality (75.1% of tests) and coverage (8.9 out of 10).
Every eSIM here that names a network lists AIS. Nomad names all three, Airalo and Ubigi add True, and Sim Local adds dtac. Saily and Yesim don't say.
A Thailand plan covers Thailand only. None of the providers here says its plan also works in Cambodia, Laos, Malaysia or Myanmar, so an overland trip needs a regional plan.
Airalo says its plan covers the mainland and the islands, including Phuket, Koh Samui, Krabi and Phi Phi. Nomad names Bangkok, Phuket and Chiang Mai, and Saily names Bangkok, Phuket, Chiang Mai and Pattaya. Sim Local, Ubigi and Yesim don't name the islands, and none of the providers mentions Koh Lanta.
Buy your eSIM before you leave, but start the plan once you land, or the 30 days begin in the airport queue. You can top up in the app once you're on a Thai network.
If you already know how long you're going for and how much data you need, skip to the plans. If not, Plan Match asks a few quick questions and picks a size for you.
The 6 Thailand eSIMs reviewed
Each review opens with the verdict. Specs, strengths and limitations follow.
Nomad
Our verdictShop-named True / AIS / dtac, and the six-pick 10 GB dest total is $10 once GigSky's 180-day 50 GB row knocks that shop out.
- Host network
- True / AIS / dtac (shop)
- Coverage
- Overseas territories not claimed. Shop markets Bangkok, Phuket, Chiang Mai
- Hotspot
- Yes on the Thailand shop FAQ
- Code
- ATESIM 20% off dest 10 GB. Does not apply to unlimited or Thailand 50 GB
- Unlimited, 30 days
- $33, daily cap not printed. ATESIM does not apply to unlimited
- Cheapest 10 GB 30-day dest total among the six ranked picks ($10)
- Shop names True / AIS / dtac
- Hotspot supported on the Thailand shop FAQ
- Dest cheapest unlimited 30-day country row ($33)
- Dest 50 GB country row is 10-day, not 30-day, and ATESIM 20% does not apply to Thailand 50 GB
- No 20 GB, 25 GB or 50 GB 30-day country row
- Overseas territories not claimed
Nomad's Thailand shop names True / AIS / dtac. The 10 GB 30-day SKU lists AIS and dtac on mask_network. The same shop FAQ prints: Yes, Nomad's eSIMs support tethering / hotspot. Coverage may not include overseas territories. The shop markets Bangkok, Phuket, Chiang Mai. Koh Samui and Koh Phi Phi are not on that shop as coverage.
Live-table 10 GB 30-day is $10, ATESIM 20% where the dest table prints it, matching the shop USD 10 list. That is the cheapest 10 GB dest total among the six after GigSky is removed. Dest 10 GB GigSky at $9.79 is cheaper on the dest table and is not a pick. There is no 20 GB, 25 GB or 50 GB 30-day Thailand-country row. Dest 50 GB is 10 days, $12. ATESIM 20% does not apply to Thailand 50 GB, unlimited, add-ons, business, sale, or plans under USD 5. Dest still prints ATESIM on the 10-day 50 GB row and on unlimited 30-day $33. Dest 3 GB 30-day is $6.
Sim Local
Our verdictDest's 5 GB and 20 GB 30-day Thailand wins, with AIS and dtac written on the country SKUs rather than the listing.
- Host network
- AIS, dtac (5/10/20 GB SKUs)
- Coverage
- Country SKUs print Thailand. Islands unnamed
- Hotspot
- Yes on those SKUs
- Code
- ATESIM 10% on the dest row
- Cheapest 5 GB and 20 GB 30-day rows on the live Thailand table
- 5/10/20 GB SKUs name AIS, dtac
- Hotspot and tethering yes on those SKUs
- No 25 GB or 50 GB 30-day country row
- Country SKUs do not name Phuket, Koh Samui or Koh Phi Phi
- 10 GB dest total sits behind Nomad
Sim Local is the cheapest 30-day row at 5 GB ($7.25) and 20 GB ($17.50). The 5 GB SKU, 10 GB SKU and 20 GB SKU name AIS, dtac. The same SKUs print hotspot and tethering: yes. Coverage on those SKUs is Thailand. They do not name Phuket, Koh Samui or Koh Phi Phi.
ATESIM is 10% off where the dest table prints it. Live-table 10 GB 30-day is $10.75. There is no 25 GB or 50 GB 30-day Thailand-country row. Unlimited dest rows for Sim Local are 7-day and 15-day, not 30-day. Orange Holiday World and World 3 GB sit on the same site. They are not Thailand-country dest cheapest SKUs. Shop list 10 GB US$10.50 vs dest $10.75; ranking uses dest.
310 GB dest row; shop hotspot lineSaily$10.99ATESIM · 10%
Our verdictThird on the 10 GB dest total at $10.99, with Phuket on the shop sentence and no MNO on the page.
- Host network
- Not publicly disclosed
- Coverage
- Shop names Bangkok, Phuket, Chiang Mai, Pattaya. Koh Samui not in that sentence
- Hotspot
- Unlimited access with no restrictions (shop)
- Unlimited, 30 days
- $71.99, 5 GB/day then 1 Mbps
- 3/5/10/20 GB and unlimited 30-day country rows exist on dest
- Shop names Phuket in the Thailand coverage sentence
- Shop prints an unlimited hotspot line
- 10 GB dest total undercuts Airalo and Ubigi
- Thailand shop did not name a host this pass
- Not a cheapest-at-size winner on the 30-day dest table at 5, 10, 20 or 50 GB
- Unlimited 30-day is the dearest dest unlimited row among programme shops that sell one
Saily's Thailand shop did not name a host, so the host stays unpublished. Dest already marks Saily Confirming. The shop prints: Enjoy great coverage and reliable internet across Thailand, including Bangkok, Phuket, Chiang Mai, and Pattaya. Koh Samui appears in site-wide city-code copy, not in that coverage sentence, so Koh Samui stays empty for Saily. Koh Phi Phi and Koh Lanta unnamed. The shop prints: Hotspot: Unlimited access with no restrictions.
Saily is not the cheapest 30-day row at 5, 10, 20 or 50 GB. Live-table 10 GB 30-day is $10.99, which is why it sits third. Live-table 5 GB 30-day is $7.99, behind Sim Local $7.25. Live-table 20 GB 30-day is $19.99, behind Sim Local $17.50 and Airalo $18. Unlimited 30-day is $71.99 with dest printing 5 GB/day, then 1 Mbps. Dest prints no promo code on Saily Thailand rows this pass.
4Best 50 GB 30-day price; Maew True and AISAiralo$11
Our verdictDest's 50 GB 30-day Thailand win, with True and AIS on the Maew payload and islands named there only.
- Host network
- True and AIS (Maew 10 GB payload)
- Coverage
- Mainland and islands including Phuket, Koh Samui, Krabi and Phi Phi (Maew). Koh Lanta unnamed
- Hotspot
- Not stated on the Thailand shop or Maew payload
- Unlimited, 30 days
- $49, 3 GB/day then 1 Mbps
- Cheapest 50 GB 30-day row on the live Thailand table
- Maew 10 GB payload names True and AIS
- Payload names Phuket, Koh Samui, Krabi and Phi Phi
- Unlimited 30-day exists on the live table with a printed daily cap
- Hotspot not stated on the Thailand shop or Maew payload
- 10 GB 30-day dest total ties Ubigi and sits behind Nomad, Sim Local and Saily
- dtac 10-day 50 GB voice SKU is a different line
Airalo's Thailand shop UI names True as the primary network, with +1 other. The same-origin package payload for the Maew 10 GB 30-day SKU (maew-in-30days-10gb, dest $11) says it operates on the True & AIS networks in Thailand. The networks array lists True and AIS. Other_info says coverage covers the mainland and islands, including Phuket, Koh Samui, Krabi and Phi Phi. Hotspot is not stated on that shop or payload, so it is omitted. Koh Lanta is unnamed.
Airalo is the cheapest 30-day row at 50 GB ($27.50). Live-table 10 GB 30-day is $11, tied with Ubigi; the 5 GB dest row ($8) splits that tie. Live-table 20 GB 30-day is $18, behind Sim Local $17.50. Live-table 5 GB 30-day is $8, behind Sim Local $7.25. Unlimited 30-day is $49 with dest printing 3 GB/day then 1 Mbps. The dtac-thailand 50 GB 10-day dest row at $9.90 (100 mins of local calls) is a second Airalo line. It is not the dest cheapest 10 GB or 50 GB 30-day SKU. Cite Maew, not that 10-day SKU.
5Best 25 GB 30-day priceUbigi$11TRAVELCITY10 · 10%
Our verdictDest's 25 GB 30-day Thailand row, with AIS and True Move on the country SKUs rather than the partner list.

- TRAVELCITY10 for 10% off
- Cheapest 25 GB 30-day row on the live Thailand table
- 10/25 GB 30-day SKUs name AIS and True Move
- Same 10 GB 30-day: Thailand $11, Best Asia $28
- Data sharing allowed on those SKUs

- Dest partner-list URL is not the host cite
- No 5 GB, 20 GB or 50 GB 30-day country row on dest
- 10 GB dest total ties Airalo and sits behind Nomad, Sim Local and Saily
Ubigi is the cheapest 30-day Thailand-country row at 25 GB ($24.90). The 10 GB 30-day SKU names AIS and True Move. The 25 GB 30-day SKU prints the same hosts. Those SKUs say data sharing is allowed. They do not name Phuket, Koh Samui, Koh Phi Phi or Koh Lanta. Dest currently cites the partner list; the SKU is the cite this pass. TRAVELCITY10 is 10% off where the dest table prints it. Live-table 10 GB 30-day is $11, tied with Airalo. There is no 5 GB, 20 GB or 50 GB 30-day Thailand-country row on dest. Unlimited 30-day dest is $49 with dest printing no daily cap. Do not print FUP60 as a daily GB. Same 10 GB 30-day dest: Thailand $11, Best Asia $28, Asia $42, Best World $39, World $59.
6Best 1 GB and 30 GB 30-day priceYesim$12.19TRAVELCITY · 15%
Our verdictLowest dest totals at 1 GB and 30 GB for 30 days. At 10 GB, Nomad, Sim Local, Saily, Airalo and Ubigi are all cheaper.
- Host network
- Not publicly disclosed
- Coverage
- City list on the shop. Phuket, Samui, Phi Phi, Lanta unnamed
- Hotspot
- Depends on the operator
- Code
- TRAVELCITY for 15% off

- City list printed on the country shop
- No Thai host on the product page
- Hotspot depends on the operator
- Not the cheapest 30-day row at 5, 10, 20, 25 or 50 GB
Yesim is the cheapest 30-day row at 1 GB ($3.01) and 30 GB ($26.66). The Thailand shop did not name a host on the product page, so the host stays unpublished. SwitchLess Networks is policy, not a carrier. Specs say hotspot depends on operator. That is not a yes. The shop lists Bangkok, Chiang Mai, Hat Yai, Khon Kaen, Nakhon Ratchasima, Nonthaburi, Pak Kret, Phatthaya, Surat Thani, Udon Thani, and other cities in Thailand. It does not name Phuket, Koh Samui, Koh Phi Phi or Koh Lanta.
TRAVELCITY is 15% off where the dest table prints it. Live-table 10 GB 30-day is $12.75, the dearest of the six. Live-table 5 GB 30-day is $8.11, behind Sim Local $7.25. Live-table 20 GB 30-day is $19.70, behind Sim Local $17.50. Live-table 50 GB 30-day is $39.41, behind Airalo $27.50. Unlimited 30-day is $48.49 with dest printing no daily cap. Do not invent one. Shop list 10 GB 30-day sat at $13.20 this pass. Ranking uses dest.
The bottom line
Nomad wins 10 GB among the six and dest 3 GB plus unlimited 30-day. Sim Local wins 5 GB and 20 GB. Saily sits third at 10 GB. Airalo wins 50 GB and takes the $11 10 GB tie on the 5 GB step-down. Ubigi wins 25 GB. Yesim wins 1 GB and 30 GB. Dest still prints GigSky as cheapest 10 GB at $9.79; that shop is out because the cheap 50 GB country row lasts 180 days. Hosts as locked: Nomad True / AIS / dtac on the shop; Sim Local AIS, dtac on the SKUs; Saily unpublished; Airalo True and AIS on the Maew payload; Ubigi AIS and True Move on the SKUs; Yesim unpublished. Nomad, Sim Local and Saily print a hotspot line. Yesim says it depends on the operator. Ubigi SKU says data sharing allowed. Airalo hotspot line is empty this pass.
Airalo's Maew payload names Phuket, Koh Samui, Krabi and Phi Phi. Nomad names Phuket in city marketing and hedges overseas territories. Saily names Phuket in the coverage sentence. Sim Local country SKUs, Yesim and Ubigi leave island cells empty. Koh Lanta stays empty for all six. Cambodia, Laos, Malaysia and Myanmar stay empty on Thailand-country SKUs.
Country totals sit on /thailand. Open questions on days and gigabytes go through /plan-match.
What Thailand data actually costs
Price per GB drops from $2.88/GB at 1 GB to $0.30/GB at 50 GB. Buying one size up often costs less per GB than topping up later. Full list on the live Thailand plans table.
A 50 GB plan costs 90% less per GB than a 1 GB plan. Source: All Things eSIM live plan feed, 13 November 2026.
The “unlimited” trap
Unlimited 30-day plans run $46.54 to $71.99, and 2 of the 4 publish a daily cap before speeds drop. Check the cap before you pay for a label.
How we rank Thailand eSIMs
We rank by the 30-day 10 GB country-plan price, pulled daily from each provider’s catalog. When two totals match, a host network named on the shop or SKU breaks the tie.
Thailand eSIM FAQs
Does a Thailand eSIM work on Phuket, Koh Samui, Koh Phi Phi or Koh Lanta?
Airalo Maew payload: mainland and islands, including Phuket, Koh Samui, Krabi and Phi Phi. Nomad: Phuket in city marketing; overseas hedge; Samui/Phi Phi/Lanta unnamed. Saily coverage sentence: Bangkok, Phuket, Chiang Mai, and Pattaya. Sim Local / Ubigi / Yesim do not name those islands. Koh Lanta unnamed on every shop. Mainland MNO names are not treated as island coverage.
Does it work in Cambodia, Laos, Malaysia or Myanmar?
No first-party Thailand-country shop named a land-border latch this pass, so those cells stay empty. Nomad SG-MY-TH and Ubigi Best Asia are separate products. A Thailand-only dest row is not a border-crossing plan.
What happens if I run out of data?
Buy another Thailand-country plan inside the same provider app. The dest /thailand table stays the price source for the next SKU.
Can I tether or use a hotspot?
Nomad Thailand shop FAQ: yes. Sim Local SKUs: yes. Saily shop: unlimited access with no restrictions. Yesim: depends on operator. Ubigi SKUs: data sharing allowed. Airalo: not stated.
Travel eSIM or a local Thai SIM?
A BTS week in Bangkok plus a beach stretch: travel eSIM, data only. A Thai number, or a stay that needs NBTC passport registration for a physical prepaid: AIS or True at Suvarnabhumi, Don Mueang or a convenience store. Foreigner registration sits on NBTC’s anyregis portal.
Which network will I actually use?
Nomad shop: True / AIS / dtac. Sim Local SKUs: AIS, dtac. Airalo Maew payload: True and AIS. Ubigi SKUs: AIS and True Move. Saily and Yesim: unpublished. Opensignal August 2026 is a coverage map. It does not name a host for these picks.
Will my phone take a Thailand travel eSIM?
Check the compatible-device list on the shop you are buying from, and confirm the handset is network-unlocked, before paying. A home eSIM already on the device does not by itself block a second Thailand travel profile on dual-eSIM phones.
