MicroEsim eSIM Data Plans for Brunei

MicroEsim does not provide a truly unlimited high‑speed data eSIM for Brunei. The plans labeled “Unlimited” in the catalog actually offer a data cap of 1GB per day; once that limit is reached the speed is throttled to 5Mbps and tethering is still allowed.

For travelers who need larger data allowances, MicroEsim offers fixed‑cap plans. One example is the Brunei 3 Days / Total 50GB plan, which provides 50GB of high‑speed data for three days and costs $187.82 USD; after the 50GB limit the speed drops to 128kbps. Similar fixed‑cap options exist for 5, 7, 10, and 15 days, offering a cost‑effective alternative for heavy data users.

MicroEsim does not offer eSIM plans with a phone number or SMS capability for Brunei. Travelers can only activate a data‑only MicroEsim plan. For voice and messaging, popular VoIP applications such as WhatsApp, Telegram, and iMessage work over the data connection and can be used to communicate without a local phone number.

MicroEsim currently offers 93 single-coverage data plans for Brunei. These plans provide data for use solely within Brunei and range in price from $3.86 to $424.39, with data caps varying from 500MB to 50GB. They also offer 45 plans with a daily data cap and 48 plans with a fixed data amount. No multi-country plans covering Brunei are available from this provider at this time.
