BetterRoaming does not provide Brunei eSIM plans that include a phone number or SMS functionality. The available eSIMs for Brunei are data‑only, offering internet access without local calling or messaging support. Travelers who need voice or text services can use VoIP apps such as WhatsApp, Telegram, or iMessage over the data connection, although some destinations may block or restrict these services, so it is advisable to confirm their availability in Brunei before purchase.
