Brunei ranks #20 of 31 Asia destinations by number of listed partner networks.
5G in Brunei
17 of 31 Asia destinations list 5G. 5G is listed for at least some plans. You also need a 5G-capable phone, and 5G availability varies by plan, location and device; the catalog-wide flag is not a coverage guarantee. 5G rarely changes how much data you use, only how fast it arrives.

Source and method
Figures come from the TripoSIM travel eSIM dataset (CC BY 4.0), generated from TripoSIM's live catalog on 2 November 2026: country-level observed price fields in USD, which do not verify a purchasable plan for a specific trip. Rankings compare the median price per GB across observed catalog entries in each country. This site is owned by the same company as TripoSIM, so this is first-party data, not an independent market survey. Prices, plan duration and individual terms can change; the checkout page is authoritative. A country-level network list can combine different SKUs, not networks guaranteed in any one purchased profile.
