Firsty eSIM Data Plans for Southeast Asia

Firsty provides an unlimited data eSIM plan for Southeast Asia called Firsty Free. The plan is free, lasts 1 day, and covers Indonesia, Malaysia, Philippines, Singapore, Thailand, Vietnam plus 102 other countries. Although the data cap is unlimited, the plan includes advertising, may be throttled, and the maximum speed is 256 kbps.

Because the plan is unlimited, it is subject to a fair‑usage policy: after heavy usage speeds may be reduced. If speed restrictions are a concern, contact Firsty directly to confirm whether the fair‑usage policy applies and how many GB of data remain at normal speed during the plan’s validity.

Firsty does not offer Southeast Asia eSIM plans that include a phone number or SMS capability. Only data‑only eSIM plans are available from this provider for traveling in Southeast Asia.

Travelers who need to make calls or send messages can use popular VoIP applications such as WhatsApp, Telegram, and iMessage over the data connection, which work without a local phone number or SMS service.

Firsty offers the Firsty Free plan, which covers Indonesia, Malaysia, the Philippines, Singapore, Thailand, and Vietnam in Southeast Asia. While the same plan also provides coverage in other parts of the world, the Southeast Asian countries listed above are the primary coverage areas for this provider.
