  • How can I order and pay for SMS?
    You can order SMS instantly on your dashboard once you’ve signed up. You can pay with Mobile Money (MTN & Airtel). After you’ve confirmed your payment, your SMS will be instantly credited to your account, and you can start sending SMS.
  • How can I add the contact information of the recipients?
    You can add the phone numbers of your contact list in two ways: 1. Enter manually each phone number in the dedicated box, and separe them by a coma “,”. For example: 0781234567, 0789876543, .... 2. Upload an excel file, containing all the phone numbers you want to send the message to. Ensure that all the phone numbers are located in “Column A” and that the rest of the file is empty.
  • Can I integrate the API for my own website or application?
    Of course! The API documentation is available here. Don't hesitate to send us a message if you have any question.
