Market Conditions: Rwanda has a growing mobile market with widespread SMS adoption. The major mobile operators include MTN Rwanda and Airtel Rwanda. While OTT messaging apps like WhatsApp are gaining popularity, SMS remains a critical communication channel, especially for business messaging and notifications. Android devices dominate the mobile market, with iOS having a smaller presence.
Key SMS Features and Capabilities in Rwanda
Rwanda supports most standard SMS features including concatenated messages and alphanumeric sender IDs, though two-way messaging capabilities are limited.
Two-way SMS Support
Two-way SMS is not supported in Rwanda through major SMS providers. This means businesses cannot receive replies to their messages through standard A2P SMS channels.
Concatenated Messages (Segmented SMS)
Support: Yes, concatenation is supported for most sender ID types, though support may vary by carrier. Message length rules: Standard SMS length limits apply - 160 characters for GSM-7 encoding, 70 characters for UCS-2 encoding. Encoding considerations: Both GSM-7 and UCS-2 encodings are supported. Messages using special characters will automatically use UCS-2 encoding, reducing the character limit per segment.
MMS Support
MMS messages are not directly supported in Rwanda. When attempting to send MMS, the message will be converted to SMS with an embedded URL link where recipients can view the media content. This ensures message delivery while providing access to multimedia content.
Recipient Phone Number Compatibility
Number Portability
Number portability is not available in Rwanda. This means mobile numbers remain tied to their original carrier, simplifying message routing and delivery.
Sending SMS to Landlines
Sending SMS to landline numbers is not possible in Rwanda. Attempts to send messages to landline numbers will result in delivery failure with a 400 response error (code 21614). These messages will not appear in logs and accounts will not be charged.
Compliance and Regulatory Guidelines for SMS in Rwanda
The Rwanda Utilities Regulatory Authority (RURA) oversees telecommunications services, including SMS communications. Businesses must comply with RURA's regulations for Quality of Service of Cellular Mobile and Fixed Networks Services, which cover voice, SMS, and data services.
Consent and Opt-In
Explicit Consent Required: Businesses must obtain and maintain clear records of explicit opt-in consent before sending any marketing or promotional messages. Best practices include:
Collecting consent through web forms, SMS keywords, or physical documentation
Maintaining detailed records of when and how consent was obtained
Clearly stating the types of messages subscribers will receive
Providing transparent information about message frequency
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
Commands should be supported in both English and Kinyarwanda
Responses to these commands must be processed immediately and free of charge
Do Not Call / Do Not Disturb Registries
Rwanda does not maintain a centralized Do Not Call registry. However, businesses should:
Maintain their own suppression lists of opted-out numbers
Honor opt-out requests within 24 hours
Regularly clean contact lists to remove inactive or invalid numbers
Document all opt-out requests for compliance purposes
Time Zone Sensitivity
Rwanda operates in the Central African Time zone (UTC+2). While there are no strict legal restrictions on SMS timing:
Recommended sending hours: 8:00 AM to 8:00 PM local time
Avoid sending during: Religious holidays, national holidays, and Sunday mornings
Emergency messages: Can be sent outside these hours if truly urgent
