TraveleSIM.CH eSIM Data Plans for Southeast Asia

TraveleSIM.CH does not provide an unlimited data eSIM for Southeast Asia. The provider’s plans in that region are fixed‑data offerings, such as a 50GB plan valid for 180 days or a 20GB plan valid for 30 days. For travelers who need a large amount of data, choosing one of the fixed data plans can be more cost‑effective than seeking an unlimited option, especially if the user’s usage is moderate to heavy but not extreme.

TraveleSIM.CH does not offer Southeast Asia eSIM plans that include a phone number or SMS capability. Only data‑only eSIMs are available in this region. Travelers can still use internet‑based messaging and voice services such as WhatsApp, Telegram, or iMessage over the data connection for calls and messages.

TraveleSIM.CH offers several eSIM plans that cover specific Southeast Asian countries. The Sim Card for Asia (7 areas) and the Sim Card for Asia Twenty plans provide coverage for Indonesia, Cambodia, Malaysia, Philippines, Singapore, Thailand and Vietnam. The Asia (20 areas) plan extends that group by adding Laos. The Sim Card for Global139 plan adds Brunei to the same core set of nations. Other plans such as Asia (12 areas) and the Global plan cover subsets of these countries and also reach regions beyond Southeast Asia, but for the Southeast Asian region the full coverage list is Indonesia, Cambodia, Malaysia, Philippines, Singapore, Thailand, Vietnam, Laos and Brunei.
