Somalia SMS Best Practices, Compliance, and Features

Somalia SMS Market Overview

Locale name:	Somalia
ISO code:	SO
Region	Middle East & Africa
Mobile country code (MCC)	637
Dialing Code	+252

Market Conditions: Somalia's mobile market is dominated by several key operators including Hormuud Telecom, Somtel, and Golis Telecom. SMS remains a crucial communication channel due to its reliability and widespread accessibility, particularly in areas with limited internet connectivity. While OTT messaging apps like WhatsApp are gaining popularity in urban areas, SMS continues to be the primary means of communication for business notifications and alerts due to its universal reach across both basic phones and smartphones.

Key SMS Features and Capabilities in Somalia

Somalia supports basic SMS functionality with concatenated messaging capabilities, though some advanced features like two-way SMS are limited.

Two-way SMS Support

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

Concatenated Messages (Segmented SMS)

Support: Yes, concatenated messaging is fully supported in Somalia.
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. Messages containing Arabic or Somali special characters will automatically use UCS-2 encoding, reducing the character limit per segment to 70.

MMS Support

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

Recipient Phone Number Compatibility

Number Portability

Number portability is not available in Somalia. This means mobile numbers remain tied to their original network operators, which helps ensure more reliable message routing and delivery.

Sending SMS to Landlines

Sending SMS to landline numbers is not possible in Somalia. Attempts to send messages to landline numbers will result in a failed delivery and typically generate a 400 response error (error code 21614) from SMS providers. These messages will not appear in delivery logs and will not incur charges.

Compliance and Regulatory Guidelines for SMS in Somalia

While Somalia lacks comprehensive telecommunications regulations, businesses should follow international best practices and carrier requirements. The National Communications Authority (NCA) of Somalia provides general oversight of telecommunications services, though specific SMS marketing regulations are still evolving.

Best Practices for Obtaining Consent:

Collect explicit opt-in consent before sending any marketing messages
Maintain clear records of how and when consent was obtained
Provide clear terms of service in both English and Somali
Include message frequency expectations during opt-in
Document consent collection methods and timestamps

HELP/STOP and Other Commands

While not strictly required by law, implementing standard opt-out commands is strongly recommended:

Support "STOP" for opt-out requests
Include "HELP" functionality for user support
Implement common variations like "JOOJI" (Stop in Somali)
Process opt-out requests within 24 hours
Send confirmation messages in both English and Somali

Do Not Call / Do Not Disturb Registries

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

Maintain their own suppression lists
Honor opt-out requests immediately
Keep records of opted-out numbers for at least 12 months
Regularly clean contact lists to remove inactive numbers
Implement internal do-not-contact policies

Time Zone Sensitivity

Somalia follows East Africa Time (EAT, UTC+3). Recommended messaging hours:

Weekdays: 8:00 AM to 8:00 PM EAT
Weekends: 9:00 AM to 6:00 PM EAT
Ramadan: Adjust timing to respect religious observances
Emergency messages: Can be sent outside these hours if urgent

Phone Numbers Options and SMS Sender Types for Somalia

Alphanumeric Sender ID

import { Twilio } from 'twilio';

// Initialize Twilio client with environment variables

  process.env.TWILIO_ACCOUNT_SID,
  process.env.TWILIO_AUTH_TOKEN
);

async function sendSMSToSomalia(
  to: string,
  message: string,
  senderId: string
): Promise<void> {
  try {
    // Validate Somalia phone number format
    if (!to.startsWith('+252')) {
      throw new Error('Invalid Somalia phone number format');

    console.log(`Message sent successfully: ${response.sid}`);
  } catch (error) {
    console.error('Error sending message:', error);
    throw error;
  }
}

      const response = await axios.post(
        `${this.baseUrl}/${this.servicePlanId}/batches`,
        {
          from: 'YourBrand', // Alphanumeric sender ID
          to: [to],
          body: message,
          parameters: {
            delivery_report: 'summary'
          }
        },

          headers: {
            'Authorization': `Bearer ${this.apiToken}`,
            'Content-Type': 'application/json'
          }
        }

  }

  sendSMS(
    to: string,
    message: string,

        originator: senderId,
        recipients: [to],
        body: message,
        datacoding: 'unicode' // Support for Somali characters
      }, (err: any, response: any) => {
        if (err) {
          reject(err);

import plivo from 'plivo';

class PlivoSMSService {
  private client: any;

  constructor(authId: string, authToken: string) {
    this.client = new plivo.Client(authId, authToken);
  }

  async sendSMS(
    to: string,

      });

      console.log('Message sent:', response.messageUuid[0]);
    } catch (error) {
      console.error('Plivo error:', error);
      throw error;
    }
  }
}

API Rate Limits and Throughput

Default rate limit: 100 messages per second
Batch sending recommended for large volumes
Implement exponential backoff for retry logic

Throughput Management Strategies:

class SMSQueue {
  private queue: any[] = [];
  private processing: boolean = false;
  private readonly batchSize: number = 50;
  private readonly rateLimitDelay: number = 1000; // 1 second

  async addToQueue(messages: any[]): Promise<void> {
    this.queue.push(...messages);
    if (!this.processing) {
      await this.processQueue();
    }
  }

  private async processQueue(): Promise<void> {
    this.processing = true;
    
    while (this.queue.length > 0) {
      const batch = this.queue.splice(0, this.batchSize);
      await this.sendBatch(batch);
      await new Promise(resolve => setTimeout(resolve, this.rateLimitDelay));
    }

    this.processing = false;
  }

  private async sendBatch(batch: any[]): Promise<void> {
    // Implement your preferred SMS provider's batch sending logic here
  }
}

Error Handling and Reporting

interface SMSError {
  code: string;
  message: string;
  timestamp: Date;
  recipient: string;
}

class SMSErrorHandler {
  private errors: SMSError[] = [];

  logError(error: SMSError): void {
    this.errors.push(error);
    // Implement your error logging logic (e.g., to CloudWatch, Datadog)
    console.error(`SMS Error [${error.code}]: ${error.message}`);
  }

  async retryFailedMessages(): Promise<void> {
    // Implement retry logic with exponential backoff
  }
}
