Market Conditions: Malawi's mobile market is dominated by two major operators: Telekom Networks Malawi (TNM) and Airtel Malawi. SMS remains a crucial communication channel, with TNM's network covering over 88% of the country through 2G, 3G, and 4G services. While OTT messaging apps are gaining popularity in urban areas, SMS continues to be the most reliable messaging solution due to its universal accessibility and network coverage, particularly in rural regions.
Key SMS Features and Capabilities in Malawi
Malawi supports basic SMS features including concatenated messaging and alphanumeric sender IDs, though two-way messaging capabilities are limited.
Two-way SMS Support
Two-way SMS is not supported in Malawi through most providers. This means businesses cannot receive replies to their messages through standard SMS channels.
Concatenated Messages (Segmented SMS)
Support: Yes, concatenation is supported for most sender ID types. Message length rules: Standard 160 characters per message segment using GSM-7 encoding. Encoding considerations: Messages use GSM-7 encoding for Latin alphabet and UTF-8 for local languages like Chichewa. Unicode messages are limited to 70 characters per segment.
MMS Support
MMS messages are not directly supported in Malawi. 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 devices while still enabling rich media sharing.
Recipient Phone Number Compatibility
Number Portability
Number portability is not available in Malawi. This means mobile numbers remain tied to their original network operator.
The lack of number portability simplifies message routing but requires businesses to maintain accurate carrier information for their contact lists.
Sending SMS to Landlines
Sending SMS to landline numbers is not supported in Malawi. Attempts to send messages to landline numbers will result in delivery failures, typically generating a 400 response error (code 21614) through SMS APIs, with no charges applied to the sender's account.
Compliance and Regulatory Guidelines for SMS in Malawi
The Malawi Communications Regulatory Authority (MACRA) oversees SMS communications under the Electronic Transactions and Cyber Security Act of 2016. All businesses must comply with MACRA's guidelines while conducting SMS marketing or communications campaigns.

Do Not Call / Do Not Disturb Registries

Regularly clean contact lists to remove opted-out numbers
