Best unlimited eSIM for Thailand: six brands compared
The best unlimited eSIM for Thailand depends on how much full speed data you use a day and how long you stay. When we checked on 8 October 2026, at about 1GB a day for a week or two RoamMore's Endless cost less than every 7 and 15 day unlimited plan we found. For a month it did not: Nomad's 30 day plan was the cheapest we found, and Airalo's and Ubigi's also cost less than Endless, even at 1GB a day. At 3GB a day or more, Jetpac, Airalo and Ubigi cost less for a week.
RoamMore wrote this page and sells Endless, so read it with that in mind. Every rival price below was read on the brand's own Thailand page on 8 October 2026, in US dollars, and links back to that page. Our prices come from our live catalogue and change when it does. If you spot a mistake, email [email protected] and we will fix it.
How do the unlimited Thailand eSIMs compare?
| Brand | Full speed a day | 7 days | 14 days | 30 days |
|---|---|---|---|---|
| RoamMore with BIRTHDAY30 | Endless 0.5GB, then 512 kbps | |||
| RoamMore with BIRTHDAY30 | Endless 1GB, then 1 Mbps | |||
| RoamMore with BIRTHDAY30 | Endless 3GB, then 1 Mbps | |||
| RoamMore with BIRTHDAY30 | Endless 5GB, then 384 kbps | |||
| RoamMore with BIRTHDAY30 | Endless 10GB, then 384 kbps | |||
| Airalo | 5GB, then 1 Mbps | US$21 | 15 days: US$39 | US$49 |
| Holafly | No daily amount stated | US$27.50 | 15 days: US$50.50 | US$73.90 |
| Nomad | No daily amount stated | Not sold | 10 days: US$16, a sale price | US$33, with calls |
| Jetpac | 3GB, then up to 1 Mbps | US$20.99, a sale price | 15 days: US$37.99, a sale price | US$65.99, a sale price |
| Ubigi | A total, not a day, then 2 Mbps | US$22, 25GB in all | 15 days, 30GB in all: US$35 | US$49, 60GB in all |
Endless prices any number of days, so its rows show 7, 14 and 30. Where a brand sells 10 or 15 days instead, the cell says so. Endless has no 2GB size in Thailand. Nomad and Jetpac showed some prices as discounts from a higher struck price, and a sale can end at any time. We left Saily out: its pages refused our reader both times we asked (HTTP 403), so we could not check its prices on the day.
How much full speed data do you use a day?
These are the daily amounts our plan finder uses. Not sure? Most people are Standard.
| Your use | A day | One week | Two weeks |
|---|---|---|---|
| Lite | 300MB | 2.1GB | 4.2GB |
| Standard | 1GB | 7GB | 14GB |
| Heavy | 2GB | 14GB | 28GB |
Lite is maps, messages and browsing with hotel wifi most evenings, so Endless at 0.5GB a day covers it. Standard is a full day out on your phone, about 1GB. Heavy is streaming, long video calls or sharing your connection with a laptop. Our cost and data guide breaks the figures down by app.
Which unlimited eSIM is best for your trip to Thailand?
- About 1GB a day, for a week or two. Endless is US$14.50 for a week, less than Jetpac's, Airalo's, Ubigi's and Holafly's weeks, and US$28.70 for 15 days, less than any 15 day plan in the table. Each of those gives more full speed data a day, so you pay less for less.
- 10 days. Nomad's 10 days are US$16 at a sale price, less than Endless at 1GB a day for 10 days (US$19.90). Its page states no daily amount, and the plan starts when you install it, so install it only after you land.
- A month. Nomad's 30 days are US$33 and include calls (its page says outgoing calls need an ID check at a True shop). Airalo's 30 days at 5GB a day and Ubigi's 30 days with 60GB in all are US$49 and US$49, against US$55.40 for Endless at 1GB a day. Any of the three is the better buy for a month.
- 3GB a day or more. Jetpac's week is US$20.99 at a sale price, Airalo's US$21 at 5GB a day and Ubigi's US$22 with 25GB in all, against US$23.60 for Endless at 3GB, so each is the better buy.
Endless charges one trip price for the exact number of days you pick, so a 12 day trip is priced for 12 days, not the nearest pack. Our guide to what unlimited really means explains daily amounts and the slower speeds after them.
How do the hotspot and the daily refill work?
On Endless the full speed amount refills every 24 hours, counted from when the eSIM first connects in Thailand, not at midnight. Once you use the day's amount, the eSIM keeps working at its cruising speed: 1 Mbps on the 1GB and 3GB sizes, enough for maps, messages and music, and slower on the 0.5GB, 5GB and 10GB sizes. You can share the connection as a hotspot, and what you share counts toward the day's amount.
Jetpac's page says its first 3GB every 24 hours run at full speed, then up to 1 Mbps until the next 24 hour cycle, and that its eSIM includes unlimited hotspot. Airalo states 5GB a day. Holafly lets you share 1GB a day, so a 7 day plan includes up to 7GB of shared data. Nomad's page says its eSIMs support tethering. Ubigi's plans have no daily refill: one amount covers the whole plan, then 2 Mbps.
When do the days start?
Endless starts when the eSIM first connects to a network in Thailand, so you can install it at home and it waits. Airalo's Thailand plans start on first use, Holafly's when the eSIM connects to a supported network, and Ubigi's when you arrive in a country the plan covers. Jetpac activates the pack within minutes of arrival. Nomad's Thailand unlimited plans start when the eSIM is installed, even outside Thailand, and its page asks you to install them only after you arrive.
Who should buy what?
- Buy Endless for a week or two at about 1GB a day or less. It was the cheapest 7 and 15 day option we found at that amount, the Thailand page lists the networks it uses, and a real person answers by email or WhatsApp.
- Buy Nomad for a month on a budget, or for exactly 10 days, if you can install it after you land.
- Buy Airalo or Ubigi for a month of heavier use without installing on arrival.
- Buy Jetpac, Airalo or Ubigi for a week at 3GB a day or more.
- Buy Holafly if you would rather not see any daily number, and know a network may still slow very heavy use.
How did we check these prices?
We read every rival price on 8 October 2026 on the brand's own Thailand page, in US dollars (Airalo with its own currency setting), with no codes, credits or memberships, and read each page a second time to confirm it. We did not go through any checkout. Prices change, so each one links to the page it came from, and we check them again each month. For fixed data plans in Thailand, see the best eSIM for Thailand.

Questions travellers ask
What is the best unlimited eSIM for Thailand?
It depends on your daily use and how long you stay. On 8 October 2026, at about 1GB a day for a week or two, RoamMore's Endless cost less than every 7 and 15 day unlimited plan we found. For a month, Nomad's 30 day plan was the cheapest we found, and Airalo's and Ubigi's also cost less than Endless. At 3GB a day or more, Jetpac's, Airalo's and Ubigi's weeks cost less than Endless at 3GB. RoamMore wrote this answer, and every rival price on the page links to the store it came from.
Is Airalo or Holafly better for unlimited data in Thailand?
On price and stated terms, Airalo. On 8 October 2026 Airalo's Thailand unlimited plans cost less than Holafly's for 7, 15 and 30 days, and Airalo states 5GB a day at full speed, then 1 Mbps. Holafly states no daily amount, says a network may slow heavy use for up to a day, and lets you share 1GB a day as a hotspot.
Which unlimited eSIM is cheapest for a month in Thailand?
Nomad's 30 day unlimited plan, which also includes calls, was the cheapest month we found on 8 October 2026. It states no daily amount, starts when you install it, even outside Thailand, and its page asks you to install it only after you arrive. Airalo's and Ubigi's 30 day plans also cost less than RoamMore's Endless for a month, even at 1GB a day.
Is unlimited data in Thailand really unlimited?
You never run out, but most plans limit the full speed part. Airalo gives 5GB a day and Jetpac 3GB a day before the speed drops to about 1 Mbps. Ubigi gives a set amount for the whole plan, then 2 Mbps. On Endless you choose the daily amount, and after it the eSIM keeps going at its cruising speed until the next refill.
Can I use an unlimited Thailand eSIM as a hotspot?
On Endless, yes, and what you share counts toward the day's full speed amount. Holafly's Thailand page allows 1GB of sharing a day, Jetpac's says its eSIM includes unlimited hotspot, and Nomad's says its eSIMs support tethering. Airalo's and Ubigi's Thailand pages did not say, so ask them before you buy.
When does an unlimited Thailand eSIM start counting days?
Endless starts when the eSIM first connects to a network in Thailand, so you can install it at home before you fly. Airalo and Holafly also start on first connection and Ubigi when you arrive. Nomad's Thailand unlimited plans are the exception: they start when you install them, so install those only after you land.
