SMS Guidelines and Compliance for Malawi (MW)

Understanding the SMS landscape in Malawi is crucial for effective communication. This guide provides insights into SMS regulations, message handling, and compliance requirements in Malawi, including message length and two-way SMS support.


Key Aspects of SMS Messaging in Malawi

Two-Way SMS Support

Two-way SMS is not supported in Malawi. This limitation means recipients cannot directly reply to your messages. For interactive communication, consider using web-based chat services or redirecting users to other platforms.

Number Portability

In Malawi, number portability is unavailable. Users cannot keep their mobile numbers when switching carriers. Businesses should account for this when planning customer communications.

Message Length and Concatenation

SMS messages are limited to 160 characters. Messages exceeding this length are split into concatenated segments, which appear as a single message to the receiver. Note that concatenation may vary based on encoding and sender ID.

Multimedia Messaging Service (MMS)

Standard MMS is not supported in Malawi. Instead, MMS messages are transformed into SMS with an embedded URL. Ensure multimedia content is accessible via links.

Sending SMS to Landline Numbers

SMS cannot be sent to landline numbers in Malawi. Attempts to do so will result in a 400 error (code 21614), and the message will not be delivered. Verify recipient numbers to avoid errors.


Compliance Considerations

Adhering to compliance guidelines is essential for SMS campaigns in Malawi:

  • Time Restrictions: Avoid sending promotional messages between 5pm and 8am (UTC+2) to comply with local laws.
  • Opt-In Consent: Obtain explicit opt-in consent from recipients before sending messages, particularly for marketing purposes.
  • HELP/STOP Commands: Support standard commands like HELP and STOP in the local language to allow users to manage subscriptions.
  • Do-Not-Call Registries: Respect do-not-call lists to prevent penalties and protect your brand's reputation.
