MicroEsim eSIM Data Plans for Brunei

MicroEsim does not provide a truly unlimited data eSIM for Brunei. The plans that use the word “Unlimited” in their name are actually day‑based data packages that give 1 GB per day of high‑speed data; after the limit the speed is throttled to 5000kbps. The same data cap applies across the 1‑, 3‑, 5‑, 7‑, 10‑, 15‑, 20‑, 25‑, and 30‑day “Unlimited 5Mbps” plans, so the data is not unbounded.

If a higher volume of data is required, a fixed‑data plan may be more economical. For instance, MicroEsim offers the Brunei 3 Days / Total 50GB plan, which provides 50 GB of data for three days, with speed reduced to 128kbps after the limit is reached. Similar 5‑day, 7‑day, 10‑day, and 15‑day 50 GB options are also available and can suit heavy data users who need predictable performance rather than an “unlimited” label.

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.
