These Thailand eSIM plans provide 1 GB, 3 GB or 5 GB of data for 7 or 30 days. Plans from Nomad, Saily and Yesim are compared below by data, validity, price, price per GB, network and the date each provider page was read.

|---|---|---|---|---|---|---|---|
| Yesim | 5GB 30 days | 5 GB | 30 | €7.00 | €1.40 | SwitchLess Networks; strongest available network including 5G | 2026-09-30 |
| Nomad | 3GB 30 days | 3 GB | 30 | €5.26 | €1.75 | True / AIS / dtac | 2026-09-30 |

Which Thailand plans are compared
Yesim lists a 5 GB plan for 30 days at €7.00 and a 1 GB plan for 30 days at €2.60. Nomad lists a 3 GB plan for 30 days at €5.26 and a 1 GB plan for 7 days at €4.39. Saily lists a 1 GB plan for 7 days at $2.99. The table keeps the prices in the currencies shown on the provider pages.
The 1 GB plans do not all have the same validity. Yesim's plan lasts 30 days, while Nomad's and Saily's plans last 7 days. The 3 GB Nomad plan and both Yesim plans last 30 days. The table places the days beside the data and price so those differences remain visible.
How to choose between plans
Among the plans priced in EUR, Yesim's 5 GB plan for 30 days has the lowest price per GB at €1.40. Among the plans priced in USD, Saily's 1 GB plan for 7 days has the lowest price per GB at $2.99. Price per GB only roughly compares plans of different lengths because a 30-day plan and a 7-day plan differ in days as well as in data.
The network details are also shown in the table. Yesim lists SwitchLess Networks with the strongest available network including 5G. Nomad lists True / AIS / dtac, while Saily's network is not stated. Euro and dollar prices are shown as each provider's page showed them on the read date, and they are not converted.
What to check before you buy
An eSIM is installed on the phone by scanning a QR code or entering a code from the provider. The phone must support eSIM and be unlocked from its carrier. Many travel eSIM plans carry data only, so check whether a plan includes a phone number if calls or text messages are needed.
Providers not shown and why
Airalo and Holafly also sell plans for Thailand. Their terms do not allow this site to republish their prices, so they are not in the table. Check those providers' own sites for current prices.
