Billion Connect eSIM Data Plans for Southeast Asia

Billion Connect does not provide an unlimited data eSIM plan for South East Asia. Instead, it offers fixed‑data plans. For example, the Southeast Asia eSIM [5 Countries] 30 Days 50GB plan costs $28.54 USD and the same region’s 30GB plan is $18.33 USD. Both plans have 30 days of validity, allow tethering, and include a reduced speed clause. Travelers who need unlimited data may need to look elsewhere, while for most users, a fixed‑data plan such as one of these is typically more cost‑effective unless their consumption is extremely high.

Billion Connect does not provide eSIM plans for South East Asia that include a phone number or SMS capability. Travelers who choose Billion Connect can only access data‑only eSIMs, and can use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection for voice and messaging.

The coverage included within Billion Connect’s eSIM offerings spans eight Southeast Asian countries. The dedicated Southeast Asia eSIM [5 Countries] / Day plan covers Malaysia, Indonesia, Singapore, Thailand, and Vietnam. The Global eSIM [20 Regions] / Day plan extends coverage to Cambodia in addition to those five nations. The Global eSIM [87 Regions] plan further adds Laos and the Philippines while still covering the core countries. No other approved Southeast Asian nations—Brunei, Timor‑Leste, or Myanmar—appear in any of these plans.
