Niger SMS Best Practices, Compliance, and Features

Niger SMS Market Overview

Market Conditions: Niger's mobile market is dominated by major operators including Moov Africa Niger and Airtel. SMS remains a crucial communication channel in Niger, particularly for business messaging and notifications. While OTT messaging apps are gaining popularity in urban areas, SMS maintains high penetration rates due to its reliability and universal device support. Android devices significantly outnumber iOS in the market, reflecting broader African mobile usage patterns.

Key SMS Features and Capabilities in Niger

Niger supports basic SMS functionality with some limitations on advanced features, while maintaining standard message delivery capabilities across major mobile networks.

Two-way SMS Support

Two-way SMS is not supported in Niger according to current network capabilities. Messages can only be sent one-way from businesses to consumers, limiting interactive messaging campaigns.

Concatenated Messages (Segmented SMS)

Support: Yes, concatenated messages are supported, though support may vary by sender ID type.
Message length rules: Standard SMS length limits apply - 160 characters for GSM-7 encoding, 70 characters for Unicode.
Encoding considerations: Both GSM-7 and UCS-2 encodings are supported, with message splitting occurring at different thresholds based on the chosen encoding.

MMS Support

MMS messages are not directly supported in Niger. When attempting to send MMS, messages are 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 Niger. 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 Niger. Attempts to send messages to landline numbers will result in delivery failure and API error responses (400 response with error code 21614). Messages will not appear in logs and accounts will not be charged for failed attempts.

Compliance and Regulatory Guidelines for SMS in Niger

SMS communications in Niger are regulated by the Autorité de Régulation des Communications Électroniques et de la Poste (ARCEP). While specific SMS marketing regulations are still evolving, businesses must follow general telecommunications guidelines and international best practices.

Consent and Opt-In

Explicit Consent Required: You must obtain and document explicit opt-in consent before sending marketing or non-essential messages. Best practices include:

• Maintaining clear records of how and when consent was obtained
• Using double opt-in processes for marketing lists
• Providing clear terms and conditions at signup
• Regularly updating consent records

HELP/STOP and Other Commands

Do Not Call / Do Not Disturb Registries

Niger currently does not maintain a centralized Do Not Call or Do Not Disturb registry. However, businesses should:

• Maintain their own suppression lists
• Honor opt-out requests within 24 hours
• Implement proper opt-out tracking systems
• Regularly clean contact lists to remove unsubscribed numbers

Time Zone Sensitivity

Niger follows UTC+1 time zone. While no strict messaging hours are mandated:
