Frequently Asked Questions

A bulk SMS gateway is a service that enables the automated sending of large volumes of SMS messages via an internet-connected platform or API. It acts as a bridge between software applications and mobile networks to ensure quick and reliable message delivery.

To send 10,000 SMS at once:

  1. Register with a reliable bulk SMS provider like Celcom Africa.
  2. Upload your list of 10,000 verified contacts (CSV or Excel).
  3. Compose your message.
  4. Use a custom sender ID (optional but recommended).
  5. Click “Send” or schedule for later.

Ensure you have enough SMS credits and an approved sender ID to avoid delays.

Bulk SMS prices in Kenya typically range from KES 0.25 to KES 1.50 per SMS, depending on volume, delivery route (standard or premium), and sender ID status.

Celcom Africa offers the most affordable rates from KES 0.25 to 0.60, with discounts for large volumes.

A Bulk SMS API is an application programming interface that allows businesses or developers to integrate SMS sending functionality into their software, apps, CRMs, or websites. It enables automation of SMS notifications, OTPs, alerts, and marketing campaigns directly from your system.

Some SMS providers offer limited free credits or trial access to their SMS API, but regular usage requires purchasing SMS credits. Celcom Africa offers free testing API keys for developers and businesses looking to evaluate the service before full integration.
