Djibouti SMS Best Practices, Compliance, and Features

Djibouti SMS Market Overview

Market Conditions: Djibouti's mobile market is characterized by a growing SMS adoption rate, with telecommunications services primarily provided through Djibouti Telecom, the country's main operator. While OTT messaging apps like WhatsApp and Telegram are gaining popularity, particularly in urban areas, SMS remains a reliable communication channel due to its universal accessibility and network independence. The mobile market shows a mix of Android and iOS devices, with Android having a larger market share due to the availability of more affordable handsets.

Key SMS Features and Capabilities in Djibouti

Djibouti supports standard SMS features including concatenated messaging and number portability, though two-way SMS functionality is limited.

Two-way SMS Support

Two-way SMS is not supported in Djibouti for A2P (Application-to-Person) messaging.
This limitation means businesses should design their SMS strategies around one-way communication flows.

Concatenated Messages (Segmented SMS)

Support: Yes, concatenation is supported for most sender ID types.
Message length rules: Standard 160 characters per message segment using GSM-7 encoding.
Encoding considerations: Messages using GSM-7 encoding allow 160 characters, while UCS-2 encoding (for special characters and non-Latin alphabets) allows 70 characters per segment.

MMS Support

MMS messages are automatically converted to SMS with an embedded URL link for accessing multimedia content.
Best practice is to use short URLs and include clear instructions for accessing the content.

Recipient Phone Number Compatibility

Number Portability

Number portability is available in Djibouti.
While this affects routing, modern SMS providers automatically handle number portability to ensure reliable delivery.

Sending SMS to Landlines

Sending SMS to landline numbers is not possible in Djibouti.
Attempts to send SMS to landline numbers will result in a failed delivery and an error response (400 error code 21614) from the SMS API.

Compliance and Regulatory Guidelines for SMS in Djibouti

SMS communications in Djibouti are regulated by the MINISTÈRE DE LA COMMUNICATION, DE LA CULTURE, CHARGÉ DES POSTES ET TÉLÉCOMMUNICATIONS (MCCPT).

    // Ensure phone number is in E.164 format for Djibouti (+253)
    const formattedNumber = to.startsWith('+253') ? to : `+253${to}`;

    const response = await client.messages.create({
      body: message,
      from: senderId, // Alphanumeric sender ID or Twilio number
      to: formattedNumber,
    });
