eSimfly eSIM Data Plans for Brunei

eSimfly does not provide a truly unlimited high‑speed data plan for Brunei. The plans labelled “Unlimited” offer only 1 GB of network data, either as a fixed 1 GB total or 1 GB per day; after the cap is reached the connection is throttled.

Travelers looking for larger data allowances can choose fixed‑data options such as the 20 GB plan valid for 30 days at US$85, the 10 GB plan valid for 30 days at US$112.15, or the 20 GB plan valid for 365 days at around US$99. These larger‑data plans are typically more cost‑effective for users who need more high‑speed usage.

eSimfly does not provide a Brunei eSIM that includes a phone number with outbound or inbound voice or SMS capability. Only data‑only eSIM options are available from eSimfly for Brunei. Travelers can use popular VoIP applications such as WhatsApp, Telegram, and iMessage over the data connection for calls and messaging.

eSimfly provides 16 single‑country data plans and 12 multi‑country data plans for travelers in Brunei. The plans range in price from roughly $7.82 to $183.26 and offer data caps between 1 GB and 20 GB, with validity periods that span 1 to 365 days. Some of the options are structured with a daily data cap—where a specified amount of data is allowed each day of the plan’s validity—while others use a fixed data cap that provides a total data allotment for the entire period. Tethering is permitted on many of the plans, giving users the flexibility to share the connection with other devices.
