Best eSIM for Thailand
Thailand is the bargain bin of this directory. Nomad, Saily and Airalo all sit near US$10–11 for 10 GB / 30 days. Holafly’s US$73.90 unlimited month looks expensive here because fixed data is so cheap.
Comparison — Thailand
Approx USD list (~31 Aug 2026). Ubigi’s Thailand catalogue mixes short 10 GB packs and recurring monthly plans — check validity carefully.
| Provider | Data | Days | Approx price | Hotspot | Best for |
|---|---|---|---|---|---|
| Nomad Value | 10 GB | 30 | US$10 | Yes | Cheapest fixed 10 GB; True/AIS/dtac |
| Saily | 10 GB | 30 | US$10.99 | Yes | Almost as cheap; solid app |
| Airalo | 10 GB | 30 | US$11 | Yes | Easy top-ups; True + partner |
| Ubigi | 10 GB | 7 | ~US$9 | Yes | Short stays; also sells monthly recurring |
| Holafly | Unlimited* | 30 | ~US$73.90 | Capped prepaid hotspot | Only for heavy daily phone data |
Quick take
Buy Nomad or Saily 10 GB unless you know you’ll need more. Nomad’s Thailand unlimited (~US$33 / 30 days in older checks) can beat Holafly if you want a soft-unlimited option. Airport physical SIMs still work but need passport registration — a travel eSIM usually skips that queue.
FAQ
Is a travel eSIM cheaper than roaming?
Usually yes — a 10 GB travel eSIM typically costs a fraction of daily roaming passes from home carriers. Heavy users should still compare per-GB prices.
When should I install my travel eSIM?
Install it at home on Wi-Fi a day or two before you fly, but keep it switched off until you land, because many plans start their validity on first connection.
Is 'unlimited' eSIM data really unlimited?
Rarely. Most unlimited plans slow you down after a daily fair-use cap (often 1–5 GB/day) and limit hotspot use. Check the cap before you buy.
