TooSim eSIM Data Plans for Southeast Asia

No, TooSim does not provide an unlimited data eSIM for South East Asia. All of the available plans list a concrete data cap, with the largest option being the Asia 50GB, 30 days plan. Travelers who need more data than the plan offers may consider bundling multiple fixed‑data packages or extending a plan’s validity, though such options are not currently listed by TooSim. For users who consume a large amount of data, choosing a fixed data plan such as the Asia 50GB, 30 days or the Asia 20GB, 30 days package can still represent a cost‑effective choice because it offers a predictable data allowance and allows tethering across Indonesia, Malaysia, Singapore, Thailand, Vietnam and additional neighboring countries.

TooSim does not offer eSIM plans for South East Asia that include a local phone number or SMS capability. Travelers who need messaging or calls can use the data allowance from a TooSim eSIM plan to access VoIP services such as WhatsApp, Telegram, or iMessage, which work over an internet connection.

TooSim offers eSIM plans covering several countries in South East Asia. The “Asia” plan provides coverage in Indonesia, Malaysia, Singapore, Thailand, and Vietnam. Their “Global” plan also includes these same countries. It’s worth noting that the “Global” plan extends coverage to numerous other locations outside of South East Asia, including territories in Europe, North America, and Oceania.
