Zwitchy eSIM Data Plans for Southeast Asia

Zwitchy does not provide a truly unlimited data eSIM for Southeast Asia.
All plans branded “Unlimited” grant 1 GB of high‑speed data per day for the stated validity period, and once the daily allotment is reached the speed is throttled to 1000 kbps.

For travelers who need more continuous data, Zwitchy offers fixed data plans such as the “South East Asia 50 GB 30 days” for $69.50 USD and the “South East Asia 30 GB 30 days” for $44.00 USD. These plans deliver a larger hard data allowance over the same period without the daily reduction in speed.

Zwitchy does not offer Southeast Asia eSIM plans that include a phone number or SMS capability; only data‑only plans are available. Travelers who need voice and text communications can use VoIP applications such as WhatsApp, Telegram or iMessage over the data connection. However, some destinations in Southeast Asia may block or restrict access to particular apps or VoIP services, so it is advisable to verify that the services you rely on are usable in the specific country before purchasing a plan.

Zwitchy's “South East Asia” plan covers Indonesia, Cambodia, Laos, Malaysia, the Philippines, Singapore, Thailand, and Vietnam, while the broader “Global” plan adds Brunei to that list; the “Asia” plan offers the same Southeast Asian coverage as the “South East Asia” plan.
