eSIMCard eSIM Data Plans for Southeast Asia

eSIMCard does not provide truly unlimited high‑speed data eSIM plans for Southeast Asia. The plans that carry the label “Unlimited” actually limit usage to 1 GB per day (or 1 GB total for the 1‑day option) and, once that cap is reached, the connection speed is throttled to 500 kbps.

For travelers who need more data at high speed, eSIMCard offers larger fixed‑data plans. For example, a 100 GB data plan valid for 90 days and a separate 100 GB plan valid for 180 days are both available and cover Indonesia, Malaysia, Singapore, Thailand, Vietnam and other Southeast Asian countries. These plans can be more cost‑effective for heavy data users.

eSIMCard does not provide Southeast Asia eSIM plans that include a phone number or SMS capability. The provider only offers data‑only eSIMs for the region. Travelers who need voice or messaging can use popular VoIP applications such as WhatsApp, Telegram, or iMessage, which work over the data connection.

eSIMCard’s eSIM plans cover eight of the eleven Southeast Asian countries on the approved list. Indonesia, Malaysia, Singapore, Thailand and Vietnam are consistently included across plans such as “eSIM Data For in Asia” and “Unlimited eSIM Data For in Global.” The plans “eSIM, , , Global (Lite), Unthrottled, ” “Global Max Data for, ” and both variants of “eSIM, , , Global, Unthrottled” extend coverage to Cambodia, Laos and the Philippines. No eSIMCard plan currently lists Brunei, Myanmar or Timor‑Leste.
