We compared official Thailand plan pages from Airalo, Saily, Nomad, and Holafly, plus Airalo’s official unlimited fair-use policy, all checked November 10, 2026. We have not run speed tests and we do not invent scores. Official Nomad lists both a 7-day and a 10-day unlimited plan at $15; we report both official figures. Official Saily listed an unlimited option at $38.99 and a 15-day block also showing $38.99; the official FAQ says unlimited plans get 5 GB of high-speed data per day with no slowdowns. Confirm the live checkout price, the network list, and that your phone is unlocked and eSIM-compatible before you buy. A Southeast Asia regional plan is a different product.

The picks in detail
1. Nomad
Best for: The lowest official 7-day unlimited Thailand price ($15), plus a short official fixed-data ladderNomad’s official Thailand page listed unlimited plans of $9 / 3 days, $13 / 5 days, and $15 for both 7 days and 10 days. We are reporting both official $15 figures, not treating one as an error. Official fixed plans include 1 GB / 7 days at $5, 3 GB / 30 days at $6, 5 GB at $8, 10 GB at $10, and 50 GB / 10 days at $15. Official networks are AIS and True — not DTAC, which appears on Airalo’s and Holafly’s official Thailand pages. Official installation language: activate within 60 days of purchase or the plan starts automatically. We did not find an official daily fair-use gigabyte figure for Nomad’s unlimited Thailand plans.

The official page listed an unlimited option at $38.99 and also showed a 15-day block at $38.99; we are citing both official presentations rather than choosing one. The official FAQ says unlimited plans get 5 GB of high-speed data per day with no slowdowns — that is a daily high-speed allotment, not an uncapped high-speed promise, and it is Thailand-page language, not something we are copying onto other countries. Official hotspot language: no restrictions or limitations. Official activation: 180 days, then automatic. Official language: this Thailand plan does not cover Malaysia. Networks were not named on the official page.

Also considered
Official Airalo and Holafly pages also showed regional Asia or Southeast Asia starting prices. Those plans are not Thailand-only and are not in this table; confirm the country list. Official Saily language says a Thailand plan does not cover Malaysia.
Who should skip this guide
- Readers who want a scored “best Thailand eSIM” or a speed-test winner. We have not tested these networks.
- People shopping for a regional Southeast Asia or Asia plan rather than a Thailand-only plan. Official brand pages also offer regional plans; confirm the country list, especially if you will cross into Malaysia.
- Travelers whose phone is locked or not eSIM-capable. Check the official compatibility list for your device.

“Unlimited” on a travel eSIM is usually a daily high-speed allowance, then a slower speed, not uncapped 5G.
