Yesim eSIM Data Plans for Thailand

Yesim offers unlimited‑data eSIM plans for Thailand that are available for validity periods from 1 day up to 80 days, with prices ranging from $3.54 for a 1‑day pass to $128.53 for an 80‑day pass. Each plan provides 5G coverage in Thailand, allows tethering, and normally delivers high‑speed data but may be throttled after heavy usage.

Because speed throttling is part of a Fair Usage Policy, users who are concerned about potential reductions in speed should contact Yesim directly to confirm whether the policy applies and what the typical amount of data is available at normal speed.

Yesim does not provide Thailand eSIM plans that include a phone number or SMS capability. Only data‑only eSIM offerings are available from the provider for Thailand. Travelers can still use VoIP services such as WhatsApp, Telegram, and iMessage over the data connection for voice calls and messaging.

Yesim currently offers 13 single‑country plans that cover Thailand alone and 35 multi‑country plans that include Thailand as part of a broader regional package. Prices for these plans range from about $0.53 to $234.66, with data caps spanning from 500 MB up to unlimited. Validity periods vary from one day to a full year. Some of the plans allow tethering and are only available to new users. In general, the single‑country options provide a fixed data amount for Thailand, whereas the multi‑country plans may feature a daily data cap that can be used across the covered countries.
