Yesim eSIM Data Plans for Thailand

Yesim offers several unlimited eSIM plans for Thailand. The plans start at $8.15 USD for a 1‑day validity and increase to $36.10 USD for a 30‑day validity. Data remains unlimited, but the provider notes that speed may be throttled after heavy usage under its Fair Usage Policy. For maximum assurance, travelers should contact Yesim directly to confirm whether the Fair Usage Policy applies and what typical data allowance 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 offers a total of 36 data plans for Thailand, split into 8 single‑country options that provide data for use only within Thailand and 28 multi‑country plans that include Thailand as part of a broader regional or global coverage. The plans cover a price range from about $0.52 to $126.94 and data caps that go from 500 MB up to unlimited. In the single‑country plans all data is usable solely inside Thailand, whereas the multi‑country plans may be used across Thailand and several other destinations.
