Yesim eSIM Data Plans for Southeast Asia

Yesim offers unlimited data eSIM plans for Southeast Asia. The plans are priced between $8.26 USD for a 1 day validity and $63.69 USD for a 30 days validity, and each includes the option for tethering. The plans note that speed may be throttled after heavy usage, indicating a Fair Usage Policy. Travelers who are concerned about possible speed restrictions should contact Yesim to confirm the specific FUP limits and typical data amounts available at normal speed.

Yesim does not provide Southeast Asia eSIM plans that include a phone number or SMS capability. All available plans are data‑only, meaning you can use the data connection for internet access but cannot make traditional voice calls or send SMS messages via the network. However, travelers can still communicate by using VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection.

Yesim offers eSIM plans that cover six core Southeast Asian countries—Indonesia, Malaysia, Philippines, Singapore, Thailand, and Vietnam—across its South East Asia, Asia Pacific, Global Plus Package, and Global Package offerings; additionally, the Asia Pacific and Global Plus Package extend coverage to Cambodia. No plan includes Laos, Brunei, Timor‑Leste, or Myanmar.
