Ohayu eSIM Data Plans for Brunei

Yes, Ohayu offers an unlimited data eSIM plan for Brunei. The plan, called Unlimited Monthly Trial, provides unlimited data for 30 days at a price of $39.99 USD. It allows tethering, may throttle speed after heavy use, and has a maximum speed of 1000 kbps on 5G networks. The coverage includes Brunei and 124 additional countries.

Because the plan is unlimited, speeds may be reduced after heavy usage under a Fair Usage Policy. Travelers who are concerned about potential speed restrictions should contact Ohayu to confirm the typical amount of data available at normal speed.

Ohayu does not provide a Brunei eSIM plan that includes a local phone number or SMS capability; only data‑only plans are offered by the provider. Travelers wishing to make voice calls or send text messages must rely on VoIP applications that work over the internet. Popular options such as WhatsApp, Telegram, and iMessage can generally be used through the data connection, but some destinations restrict or block certain services, so users should confirm that the apps they need are accessible in Brunei before purchasing.

Ohayu offers six single‑country plans and two multi‑country plans for Brunei. The plans range in price from $18.99 to $192.99 and provide data caps from 2 GB up to unlimited. Validity periods span 7 to 90 days. Depending on the specific plan, users may receive a fixed data amount or a daily data cap that can be applied across the validity period.
