Billion Connect eSIM Data Plans for Southeast Asia

Billion Connect provides unlimited data eSIM plans that cover Southeast Asia, specifically Indonesia, Cambodia, Malaysia, Singapore, Thailand, Vietnam and an additional 14 nearby countries. The plans are called Global eSIM [20 Regions] Unlimited /Day and are available for periods ranging from 1 day (priced at $2.53 USD) to 30 days (priced at $46.04 USD). These unlimited plans allow tethering and state that speed may be throttled after heavy usage, reflecting the Fair Usage Policy that may reduce data rates once a certain threshold is reached.

Users who want to confirm the exact level of data available at normal speed and whether a Fair Usage Policy applies on their specific itinerary should contact Billion Connect directly for clarification.

Billion Connect does not provide a local phone number or SMS capability for its Southeast Asia eSIM plans. The provider’s offerings in this region are strictly data‑only, with no built‑in telephony services such as inbound or outbound voice calls or text messaging.

Travelers who need to make calls or send messages can rely on internet‑based VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection. These services use the data allowance rather than a traditional phone number or SMS network.

Billion Connect offers several eSIM plans that cover the following Southeast Asian countries: Indonesia, Malaysia, Singapore, Thailand, Vietnam, Cambodia, Laos and the Philippines. The Southeast Asia eSIM [5 Countries] /Day plan specifically serves Indonesia, Malaysia, Singapore, Thailand and Vietnam, while the Global eSIM [20 Regions] /Day plan covers those five countries plus Cambodia. The Global eSIM [87 Regions] plan expands coverage further to include Laos and the Philippines in addition to the same five core countries, and in all cases these plans also address a broader set of regions outside Southeast Asia.
