4S eSIM eSIM Data Plans for Brunei

4S eSIM does not provide a truly unlimited high‑speed data eSIM for Brunei. The plans that bear “Unlimited” in their name actually have a hard data cap and include a reduced speed of 1000 kbps after the allotted data is used. Therefore those plans are not unlimited in the sense of unlimited high‑speed data without limits.

Travelers who need large amounts of data can choose fixed data plans instead. For example, 4S eSIM offers a 50GB plan that is valid for 5 days, 7 days, 15 days, 30 days, or up to 90 days, with no speed throttling once the data is exhausted. Other options include 10 GB, 20 GB, 30 GB, 50 GB, and 30 GB over 30 days plans, each providing a generous data allowance and consistent high‑speed service throughout the validity period.

4S eSIM does not offer a Brunei plan that includes a local phone number or SMS capability. The provider only sells data‑only eSIMs for Brunei, so travelers who need voice or text messages must use VoIP applications such as WhatsApp, Telegram or iMessage over the data connection. Those apps may work in Brunei, but some destinations can block or restrict access to specific services, so users should verify that their preferred VoIP services are available in Brunei before purchasing a 4S eSIM plan.

4S eSIM offers 53 single‑country data plans for Brunei, with no multi‑country options available. The plans include 11 daily data cap options and 42 fixed data cap options. Prices range from $3.64 to $188.20, while data caps span from 714 MB up to 50 GB.
