SMS API for Brunei: bulk SMS to +673 numbers

Brunei is a small Southeast Asian nation on the island of Borneo, with Bandar Seri Begawan as its capital and a strong economy driven by oil and gas exports. Local banks, government agencies, and logistics companies integrate SMS into their systems for customer communication. Messages are triggered by events like account logins, utility bill reminders, or package delivery updates. Developers choose SMS because it reliably reaches all mobile users, including those with basic phones or visiting from abroad.

Number format in Brunei

Mobile numbers in Brunei have 7 digits after +673 and no trunk prefix, so the local form 712 3456 becomes +673 712 3456 in the to field.

Alphabet and segments

Indonesian and Malay text stays inside the GSM-7 alphabet, so one segment to Brunei holds 160 characters and each part of a longer text 153. Watch for curly quotes and emoji copied from other tools: one of them moves the whole text to Unicode at 70 characters per segment, and POST /v1/estimates shows the encoding before you send.

Time zone and timing

Brunei keeps UTC+8 all year with no clock change, so 09:00 in Brunei is always 01:00 UTC. send_at takes UTC or any ISO 8601 offset, and the console scheduler converts from your own time zone.

Send to Brunei with one request

The answer comes back at once with the message id, the country the number was matched to (BN) and the price. A delivered or failed event follows on your webhook, and a failed message is refunded.

For a list, send the same text to up to 10,000 numbers with POST /v1/batches, or a personal text per number in messages.
