Ubigi eSIM Data Plans for Southeast Asia

Ubigi does not offer any unlimited data eSIM plans for Southeast Asia. All of its offerings for the region provide capped data allowances. For example, the BEST ASIA plan delivers 60 GB of data for 30 days at $78.00 USD, while a smaller 25 GB 30‑day plan is available for $44.00 USD. These are only a few of the fixed‑data options available; a full list includes several plans with 50 GB over 180 days and 25 GB over 90 days.

Choosing a fixed‑data plan can be more cost‑effective for most travelers, unless you anticipate consuming data beyond the capped amounts.

Ubigi does not offer any Southeast Asia eSIM plans that include a phone number or SMS capability. Its available plans are data‑only, with no inbound or outbound voice or text options.

Travelers who need to make calls or send messages can use internet‑based services such as WhatsApp, Telegram, or iMessage over the data connection provided by the eSIM.

Ubigi offers three plans that cover the Southeast Asian countries as follows: the BEST ASIA plan includes Indonesia, Cambodia, Laos, Malaysia, Philippines, Singapore, Thailand and Vietnam; the ASIA plan expands this coverage by adding Brunei; and the WORLD plan likewise contains all those countries plus Brunei.
