Uganda SMS Best Practices, Compliance, and Features

Uganda SMS Market Overview

Market Conditions: Uganda has a vibrant mobile communications market dominated by major operators including MTN Uganda (market leader), Airtel Uganda, and Africell. SMS remains a crucial communication channel, particularly for business messaging and notifications, despite growing adoption of OTT messaging apps. Android devices dominate the smartphone market, with iOS having minimal presence. The market shows strong potential for A2P (Application-to-Person) messaging services, especially for business communications and authentication purposes.

Key SMS Features and Capabilities in Uganda

Uganda supports most standard SMS features including concatenated messages and alphanumeric sender IDs, though two-way messaging capabilities are limited and MMS requires conversion to SMS with URL links.

Two-way SMS Support

Two-way SMS is not supported in Uganda through major SMS providers. This limitation affects interactive messaging campaigns and automated response systems.

Concatenated Messages (Segmented SMS)

Support: Yes, concatenation is supported, though availability may vary based on sender ID type.
Message length rules: Messages are split according to standard SMS character limits - 160 characters for GSM-7 encoding and 70 characters for UCS-2 encoding.
Encoding considerations: Both GSM-7 and UCS-2 encodings are supported, with UCS-2 being essential for messages containing non-Latin characters.

MMS Support

MMS messages are not directly supported in Uganda. Instead, MMS content is automatically converted to SMS with an embedded URL link where recipients can view the multimedia content. This ensures compatibility while still enabling rich media sharing capabilities.

Recipient Phone Number Compatibility

Number Portability

Number portability is not available in Uganda. This means mobile numbers remain tied to their original network operators, simplifying message routing but limiting consumer flexibility.

Sending SMS to Landlines

Sending SMS to landline numbers is not supported in Uganda. Attempts to send messages to landline numbers will result in delivery failure, typically generating a 400 response with error code 21614 through SMS APIs, and no charges will be incurred.

Compliance and Regulatory Guidelines for SMS in Uganda

SMS communications in Uganda are regulated by the Uganda Communications Commission (UCC). While specific SMS marketing regulations are still evolving, businesses must comply with general telecommunications laws and data protection guidelines. The Data Protection and Privacy Act 2019 provides the framework for handling personal data, including phone numbers.

Consent and Opt-In

Explicit Consent Requirements:

• Obtain clear, documented opt-in consent before sending marketing messages
• Maintain detailed records of when and how consent was obtained
• Include your business name and purpose in consent requests
• Provide clear terms and conditions regarding message frequency and content

Best Practices for Consent Collection:

• Use double opt-in processes for marketing lists
• Document consent timestamps and methods
• Store consent records securely and accessibly
• Regular audit and cleanup of consent records

HELP/STOP and Other Commands

• All SMS campaigns must support standard opt-out keywords (STOP, CANCEL, END, UNSUBSCRIBE)
• HELP messages should provide customer support contact information
• Consider supporting both English and Swahili keywords
• Implement immediate processing of opt-out requests
• Send confirmation messages for opt-out requests

Do Not Call / Do Not Disturb Registries

Uganda currently does not maintain an official Do Not Call registry. However, businesses should:

• Maintain their own suppression lists
• Honor opt-out requests immediately
• Implement a system to track and manage blocked numbers
• Regularly update suppression lists across all campaigns
• Share suppression lists across departments to ensure compliance

Time Zone Sensitivity

Uganda operates in East Africa Time (EAT, UTC+3). Best practices include:

• Send messages between 8:00 AM and 8:00 PM local time
• Avoid sending during major religious observances
• Consider cultural events and public holidays
• Only send outside these hours for urgent or emergency communications

// Add messages to queue
async function queueMessages(messages: Message[]) {

      }
    });
  }
}

Error Handling and Reporting

• Implement comprehensive error logging
• Track delivery rates by carrier

const errorHandler = (error: any) => {
  logger.error({
    message: 'SMS sending failed',
    error: error.message,
    code: error.code,
    timestamp: new Date().toISOString(),
    // Additional context
    recipient: error.recipient,
    messageId: error.messageId
  });
  
  // Implement appropriate retry logic
  if (isRetryableError(error)) {
    return scheduleRetry(error.messageId);
  }
  
  return false;
};
