YonoSIM eSIM Data Plans for Southeast Asia

YonoSIM does not provide any unlimited data eSIM plans for Southeast Asia. All of its offerings are fixed‑data packages. For example, the 50GB plan valid for 180 days covering Indonesia, Cambodia, Malaysia, Philippines, Singapore, Thailand, and Vietnam costs $76.99 USD, while a 20GB plan valid for 30 days in the same region costs $38.99 USD. Other 20GB‑30‑day options are available with slightly higher prices and broader coverage.

Choosing a fixed‑data plan can be more cost effective for most travelers, especially those who are not extremely heavy data users. Unlimited plans would typically only benefit very high‑consumption travelers, and YonoSIM currently does not offer such an option.

YonoSIM does not provide eSIM plans in Southeast Asia that include a local phone number or SMS capability. All Southeast Asia eSIM offerings from YonoSIM are data‑only, without voice or text messaging services. Travelers who need to communicate can use popular VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection, but should verify that these apps are accessible in their specific destinations before purchasing a plan.

YonoSIM offers several eSIM plans that cover a wide range of Southeast Asian countries. The Asian‑focused plans—Asia (7 areas), Asia‑20, Asia (12 areas), and Asia (20 areas)—include Indonesia, Cambodia, Malaysia, Singapore, Thailand, and Vietnam; the Asia (20 areas) plan additionally covers Laos, while the Singapore & Malaysia & Vietnam & Thailand & Indonesia /Day plan covers the same five core countries. The Global (120+ areas) plan adds the Philippines to the core set, and the Global139 plan includes Brunei as an extra Southeast Asian country. Thus, YonoSIM’s Southeast Asian coverage spans Indonesia, Cambodia, Malaysia, Philippines, Singapore, Thailand, Vietnam, Laos, and Brunei.
