Best eSIM for Thailand: five brands compared
For most trips to Thailand the best eSIM is a fixed data plan sized to your stay, and when we checked on 7 October 2026 the prices were close: Jetpac had the lowest 5GB plan for 30 days and ours came second, while Nomad had the lowest 10GB plan and Airalo's and Jetpac's also cost less than ours. If you want unlimited data and use 3GB a day or more, Jetpac's week at 3GB a day and Airalo's at 5GB a day cost less than our Endless plan at 3GB. If 1GB a day covers you, Endless costs less for a week than any unlimited week we found.
RoamMore wrote this page and sells eSIMs for Thailand, so read it with that in mind. Every rival price below was read on the brand's own Thailand page on 7 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 Thailand eSIMs compare on price?
Fixed data plans
| Brand | 5GB, 30 days | 10GB, 30 days |
|---|---|---|
| RoamMore | US$7.80 | US$12.10 |
| Airalo | US$8 | US$11 |
| Nomad | US$8 | US$10 |
| Jetpac | US$7 | US$11.50 |
Holafly does not sell fixed data plans here.
Unlimited plans
| Brand | Unlimited, 7 days | Unlimited, about two weeks | Full speed a day on unlimited |
|---|---|---|---|
| RoamMore | Endless: US$14.50 at 1GB a day, US$23.60 at 3GB | 15 days: US$28.70 at 1GB a day, US$48.20 at 3GB | You choose. At 1GB or 3GB a day, then 1 Mbps |
| Airalo | US$21 | 15 days: US$39 | 5GB, then 1 Mbps |
| Holafly | US$27.50 | 15 days: US$50.50 | No daily amount stated |
| Nomad | No 7 day plan. 10 days: US$16, a sale price | Not sold. Its Thailand unlimited plans run 10 or 30 days | No daily amount stated |
| Jetpac | US$20.99, a sale price | 15 days: US$37.99, a sale price | 3GB, then up to 1 Mbps |
The fixed plans are like for like: the same amount of data for the same 30 days. The unlimited plans are not. Each brand gives a different amount of full speed data a day, so compare the price at the daily amount you will really use, not the word unlimited. Nomad and Jetpac showed some prices as discounts from a higher struck price, and a sale can end at any time.
Which networks will you use in Thailand, and is there 5G?
Our Thailand plans list two networks, TrueMove H and DTAC, both with 5G. Airalo's Thailand page lists True and AIS, Holafly's lists True and DTAC, and Nomad's lists True, AIS and dtac across its plans. Jetpac's Thailand page did not name its networks.
5G needs a phone that supports it. Where there is no 5G, the eSIM uses 4G. The Thailand page lists every plan with its networks and speed.
Our Thailand plans connect to the internet through Hong Kong or Singapore, so a website or app may treat you as being there rather than in Thailand. Our guide to where your eSIM's internet comes out explains when that matters.
How much data do you need for a week in Thailand?
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 |
So a 10GB plan covers a week of Standard use in Thailand with room to spare, and a fortnight at that rate needs a bigger plan or a top up. If your hotel has good wifi you may be Lite; island hopping with maps, ride hailing and photo uploads pushes you toward Standard or Heavy. Our cost and data guide breaks the figures down by app.
Should you get unlimited data or a fixed plan in Thailand?
A fixed plan is usually the cheaper buy if you know roughly how much you use, because one allowance stretches across light days and busy ones. Unlimited is the simpler buy if you stream, make long video calls or would rather not watch a meter.
If you do want unlimited, compare plans at the same daily amount. For Thailand:
- At 1GB a day, Endless is US$14.50 for a week, less than Airalo's, Holafly's and Jetpac's unlimited weeks, though each of those gives you more full speed data a day. For 15 days it is US$28.70, less than any of their 15 day plans.
- For 10 days, Nomad's unlimited plan is US$16 at a sale price, against US$19.90 for 10 days of Endless at 1GB a day, so Nomad is the better buy at that price. Its page states no daily full speed amount, and the plan starts when you install it.
- At 3GB a day or more, Jetpac's week at 3GB a day is US$20.99 at a sale price and Airalo's week at 5GB a day is US$21, against US$23.60 for Endless at 3GB, so either is the better buy.
- Holafly's week is US$27.50. It states no daily amount, and says a network may slow heavy use for no more than a day.
Endless charges one 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 the daily amounts and the slower speeds after them.
When do the days start?
Our Thailand plans start when the eSIM first connects to a network in Thailand, so you can install it at home and it waits. The one exception is a 100MB trial, which starts when you install it, and the Thailand page marks it. Endless also starts on first connection there, and its full speed amount refills every 24 hours from that moment.
Airalo's Thailand plans start on first use. Nomad's fixed plans start when the eSIM connects to a network, or after 60 days if it has not, but its Thailand unlimited plan starts when you install it, even outside Thailand, and its page asks you to install it only after you arrive. Holafly's Thailand page says its plan starts when the eSIM connects to a supported network. Jetpac keeps a pack you have not activated in your account for 3 months from purchase.
Can you use a Thailand eSIM as a hotspot?
On our daily plans and on Endless, yes: sharing your connection works, and what you share counts toward the day's full speed amount. Holafly's Thailand page allows 1GB of sharing a day, so a 7 day plan includes up to 7GB of shared data. Jetpac's says hotspot sharing has no data limits, and Nomad's says its eSIMs support hotspot. If you plan to work from a laptop, ask the seller before you buy.
What should you do before you fly from New Zealand or Australia?
Install the eSIM at home on wifi a few days before you leave, and leave it switched off. When you land in Bangkok or Phuket, switch it on, set it as your data line and turn on data roaming for it. Keep your home SIM on for calls and texts, with its own data roaming off, so your carrier does not charge you for data. Our landing day checklist walks through each step.
Our prices are in US dollars, so your bank converts the payment.
When is another brand the better choice?
- You want the lowest price on a fixed plan. Jetpac's 5GB and Nomad's 10GB plans for 30 days cost less than ours.
- You want unlimited at 3GB a day or more. Jetpac and Airalo cost less for a week than Endless at 3GB a day.
- You want 10 days of unlimited. Nomad's 10 day plan, at a sale price, costs less than 10 days of Endless at 1GB a day.
- You would rather not count anything. Holafly states no daily amount at all, only that a network may slow heavy use for up to a day.
Choose RoamMore if 1GB a day of unlimited covers you, since Endless was the lowest weekly price we found at that amount and starts when you land, not when you install. A trip is priced to the exact day, there is no app to install, and a real person answers by email or WhatsApp.
How did we check these prices?
We read every rival price on 7 October 2026 on the brand's own Thailand page, in US dollars (Airalo with its own currency setting), with no codes, credits or memberships. 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.

Questions travellers ask
What is the best eSIM for Thailand?
For most trips, a fixed data plan sized to your stay. On 7 October 2026, Jetpac had the lowest 5GB plan for 30 days and ours came second, ahead of Airalo and Nomad, while Nomad had the lowest 10GB plan and Airalo's and Jetpac's also cost less than ours. Holafly's Thailand page sold unlimited plans only. If you want unlimited data at 3GB a day or more, Jetpac's and Airalo's weeks cost less than our Endless plan at 3GB a day; at 1GB a day, Endless costs less for a week than any unlimited week we found. RoamMore wrote this answer, and every rival price on the page links to the store it came from.
Which networks does a Thailand eSIM use?
It depends on the brand. Our Thailand plans list TrueMove H and DTAC, both with 5G. Airalo lists True and AIS, Holafly lists True and DTAC, and Nomad lists True, AIS and dtac. Jetpac's Thailand page did not name its networks.
Is 10GB enough for a week in Thailand?
For most people, yes. At Standard use, about 1GB a day, a week comes to about 7GB, so a 10GB plan leaves room to spare. Two weeks at that rate needs more than 10GB, so pick a bigger plan or top up.
Can I use a Thailand eSIM as a hotspot?
On our daily plans and 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 hotspot sharing has no data limits, and Nomad's says its eSIMs support hotspot. If you plan to work from a laptop, ask the seller before you buy.
When does a Thailand eSIM start?
Our Thailand plans start when the eSIM first connects to a network in Thailand, so you can install it at home before you fly. The one exception is a 100MB trial, which starts when you install it, and the Thailand page marks it. Airalo's Thailand plans also start on first use, and Nomad's fixed plans start when the eSIM connects or after 60 days, but Nomad's Thailand unlimited plan starts when you install it, so its page says to install it only after you arrive.
