Best eSIM for Thailand compared
Ubigi sells 10 GB for 30 days and Airalo sells 20 GB, so the question is whether the extra data is worth the gap. Nomad, aloSIM and Holafly are the other options.

Ubigi and Nomad both sell 10 GB for 30 days in Thailand, so the real question is how much data you'll burn.
Ubigi or Airalo
Ubigi's plan is 10 GB for 30 days at $11. Airalo's is 20 GB for 30 days at $18 (checked November 2, 2026). That's double the data, and the two prices above show what it costs.
On a two-week holiday with maps, messaging and photo uploads, 10 GB is a reasonable guess; the calculator will test it for 14 days and 10 GB. Airalo's 20 GB makes sense if you tether a laptop, stream, or stay the full month.
One flag on Airalo. Its Thailand page text says the eSIM operates on "True & AIS", but the plan data embedded in the same page lists dtac as the network. I wouldn't rely on either. Check the network on the plan screen before paying. Airalo's page also says the eSIM is rechargeable online with no expiry.
Ubigi's list doesn't name a Thai network. It also lists a 7-day, 10 GB plan at US$9 and a 15-day, 3 GB plan at US$5 (read November 2, 2026). One-off plans can be topped up, per its page. Neither Ubigi's nor Airalo's Thailand page says whether hotspot works, though Airalo's help page on tethering says it does where your device and the network support it.
The rest
Nomad's Thailand page, read November 2, 2026, offers 10 GB for 30 days at $10. The page displayed euros for its other plans: 5 GB for 30 days at EUR 7.16, and unlimited plans of 5 days (EUR 11.64), 7 days (EUR 13.43) or 10 days (EUR 15.23). Nomad's page names True, dtac and AIS as networks, and Nomad's FAQ says hotspot and tethering are supported.
aloSIM has a 5 GB plan for 30 days at $8, on AIS. Its page says hotspot works, top-ups are available and a free Hushed number comes with it. A 7-day unlimited plan costs $27. aloSIM's fair-usage note gives 3 GB a day at full speed, then 1 Mbps until the next day.
Holafly's unlimited plan priced here runs 5 days at $20.50. It uses True / DTAC. Hotspot shares 1 GB a day, and Holafly says a fair-usage policy can slow speeds for up to one day. It has no phone number.
What I'd buy
For a normal two-week trip, Ubigi's 10 GB, or Nomad's 10 GB if you want a stated hotspot policy. For a month or a laptop, Airalo's 20 GB. For a 5-day trip with heavy use, Holafly's unlimited plan removes the data arithmetic.
Nomad against Airalo gets its own page: Airalo vs Nomad. Longer stays are covered in best eSIMs for digital nomads. Pair this with the Japan comparison if you're hopping on to Tokyo, and browse all travel eSIMs.
