Togo SMS Best Practices, Compliance, and Features

Togo SMS Market Overview

Market Conditions: Togo has a growing mobile market with increasing SMS adoption for business communications and notifications. The country primarily relies on GSM networks, with major operators including Togocel and Moov Togo. While OTT messaging apps like WhatsApp are gaining popularity, SMS remains a reliable channel for reaching users across all device types, with Android being the dominant mobile platform in the region.

Key SMS Features and Capabilities in Togo

Togo supports basic SMS functionality including concatenated messages and alphanumeric sender IDs, though some advanced features like two-way SMS are not available.

Two-way SMS Support

Two-way SMS is not supported in Togo. Messages can only be sent one-way from businesses to consumers, making it suitable for notifications and alerts but not for interactive messaging campaigns.

Concatenated Messages (Segmented SMS)

Support: Yes, concatenation is supported for most sender ID types.
Message length rules: Standard SMS length of 160 characters for GSM-7 encoding, or 70 characters for Unicode (UCS-2) encoding before splitting occurs.
Encoding considerations: Both GSM-7 and UCS-2 encodings are supported, with messages automatically split and rejoined based on the character encoding used.

MMS Support

MMS messages are not directly supported in Togo. When attempting to send MMS, the message will be automatically converted to SMS with an embedded URL link where recipients can view the multimedia content. This ensures message delivery while providing access to rich media content.

Recipient Phone Number Compatibility

Number Portability

Number portability is not available in Togo. This means mobile numbers remain tied to their original carrier, which helps ensure consistent message routing and delivery.

Sending SMS to Landlines

Sending SMS to landline numbers is not possible in Togo. Attempts to send messages to landline numbers will result in a failed delivery and an error response (400 error code 21614). These messages will not appear in logs and accounts will not be charged for failed attempts.

Compliance and Regulatory Guidelines for SMS in Togo

While Togo doesn't have comprehensive SMS-specific regulations, businesses must follow general telecommunications guidelines overseen by the Autorit?? de R??gulation des Communications ??lectroniques et des Postes (ARCEP). It's recommended to align with international best practices for SMS marketing and communications.

Consent and Opt-In

Explicit Consent Requirements:

• Obtain clear, documented opt-in consent before sending marketing messages
• Maintain records of how and when consent was obtained
• Include your business name and purpose in consent requests

HELP/STOP and Other Commands

• Support standard STOP commands for opt-outs
• Include HELP keyword support for user assistance
• Consider both French (primary) and English language commands:
  • STOP/ARRETER
  • AIDE/HELP
• Acknowledge opt-out requests within 24 hours

Do Not Call / Do Not Disturb Registries

While Togo doesn't maintain an official Do Not Call registry, businesses should:

• Maintain their own suppression lists
• Honor opt-out requests immediately
• Document all opt-out requests and actions taken
• Regularly clean contact lists to remove unsubscribed numbers

Time Zone Sensitivity

Togo operates in the GMT timezone (UTC+0). Best practices include:

• Sending messages between 8:00 AM and 8:00 PM local time

SMS API integrations for Togo

Twilio

Twilio provides a robust SMS API for sending messages to Togo. Integration requires your Account SID and Auth Token from the Twilio Console.

// Initialize Twilio client with your credentials
const client = new Twilio(
  process.env.TWILIO_ACCOUNT_SID,
  process.env.TWILIO_AUTH_TOKEN
);

// Function to send SMS to Togo
async function sendSMSToTogo(
  to: string,
  message: string,
  senderId: string
): Promise<void&gt; {
  try {
    // Format phone number for Togo (add +228 if not present)
    const formattedNumber = to.startsWith('+228') ? to : `+228${to}`;
    
    // Send message
    const response = await client.messages.create({
      body: message,
      from: senderId, // Alphanumeric sender ID or Twilio number
      to: formattedNumber,
    });
    
    console.log(`Message sent successfully! SID: ${response.sid}`);
  } catch (error) {
    console.error('Error sending message:', error);
    throw error;
  }
}
