eSIM guide

The best travel eSIM for Thailand

Thailand is the cheapest destination in this comparison for mobile data, and the gap between the cheapest and the most expensive provider is absurd: $10.99 for 10GB from Saily, against $73.90 for a month from Holafly.

What a 10GB month costs in Thailand

Same plan, same duration, five sellers. USD, checked 31 August 2026.

Nomad$10 cheapest
Saily$10.99
Airalo$11

Holaflyno fixed-data plans

Holafly sells no fixed-data plans anywhere — its 30-day unlimited plan is $73.90, which is a different product and so is not plotted on the same scale.

Our pick for Thailand

Saily

Saily at $10.99 for 10GB over 30 days is the value pick, and Nomad's unlimited at $33 for a month is the cheapest unlimited anywhere in this comparison. Holafly charges the same $73.90 here that it charges in Japan, which makes Thailand the clearest case against flat global pricing.
