These unlimited plans include tethering and are marketed as high‑speed 5G, but the plan notes that speeds may be throttled after heavy usage under a Fair Usage Policy. Travelers who want to confirm the specific throttle thresholds or the amount of data that remains at normal speed should contact Billion Connect directly for clarification.
Billion Connect does not provide Southeast Asia eSIM plans that include a phone number or SMS capability; only data‑only eSIMs are available. Travelers who need voice or text messaging will need to rely on VoIP applications such as WhatsApp, Telegram, or iMessage, which use the data connection instead of a traditional phone number or SMS service.
Several Billion Connect plans cover a range of Southeast Asian countries. The “Southeast Asia eSIM [5 Countries]/Day”, “Global eSIM [19 Regions]”, “Global [85 regions]”, “Global eSIM [87 Regions]”, and “Global eSIM [155 Regions]” plans all provide coverage in Indonesia, Malaysia, Singapore, Thailand, Vietnam, Cambodia, Laos, Philippines and Brunei.
