SMS API for Cameroon: bulk SMS to +237 numbers

Cameroon, located in Central Africa, has Yaounde as its capital and Douala as its largest city, with a diverse economy including agriculture and oil. Mobile money services, delivery apps, universities, and healthcare providers send text messages from their systems. Messages notify users of transactions, order confirmations, exam results, and appointment reminders. SMS is chosen because it works on all phones, even basic models, and reaches people in rural areas without internet access.

Number format in Cameroon

Mobile numbers in Cameroon have 9 digits after +237 and no trunk prefix, so the local form 6 71 23 45 67 becomes +237 6 71 23 45 67 in the to field.

Alphabet and segments

Texts in French fit 160 GSM-7 characters per segment until they use â, ê, î, ô, û, ç, ë and ï: those letters are outside GSM-7 and turn the message into Unicode at 70 characters per segment (67 per part). For short alerts, write them without those letters to keep one segment; for longer texts, the console names each letter that changed the encoding.

Time zone and timing

Cameroon keeps UTC+1 all year with no clock change, so 09:00 in Douala is always 08:00 UTC. send_at takes UTC or any ISO 8601 offset, and the console scheduler converts from your own time zone.

Send to Cameroon with one request

The answer comes back at once with the message id, the country the number was matched to (CM) 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.
