CA orders Kenyan telcos to bypass SMS opt-outs as national warning system is tested
The Communications Authority of Kenya (CA) has ordered mobile operators to deliver government-authorised Kenya emergency SMS alerts to all active subscribers, including people whose phones or accounts have DND settings or who previously opted out of promotional messages.
The directive takes effect as the country conducts a national Early Warning System simulation on October 2 and prepares for the El Niño rains. The order applies to Safaricom, Airtel, Telkom Kenya and Jamii Telecommunications, and requires operators to give qualifying emergency communications priority across their networks.
CA issued the directive on October 1, citing the urgency of the simulation and the Government’s obligation to make important public-safety information available to the public. It specifically exempts approved emergency preparedness, disaster and El Niño-related messages from the opt-in and opt-out requirements that normally apply to commercial messaging services. The regulator has also instructed operators to refrain from applying opt-out mechanisms to such alerts and to provide the technical support needed for the exercises and any subsequent emergency response.
CA orders operators to deliver emergency messages to all active subscribers
The directive covers messages disseminated by the Government through designated platforms, including Short Code 1590. Operators have been told to deliver these communications to all active subscribers regardless of existing promotional messaging preferences, DND settings or previous opt-out arrangements.
That distinction is important because the order does not amount to a general suspension of SMS consent requirements. CA is carving out a specific category of government-authorised communications dealing with emergency preparedness, public safety, early warnings, simulation notifications and disaster response. Ordinary commercial messages remain a separate category.
The regulator is relying partly on Condition 6 of the operators’ telecommunications licence terms, which requires licensees to facilitate public information during major disasters, emergencies and crises when directed by the Government and CA. The same condition requires operators to coordinate with the Authority and follow its instructions where emergency communications are required.
CA also cites Articles 35, 33 and 46 of the Constitution, alongside the Access to Information Act, 2016. The provisions cited by the regulator cover the State’s obligation to publicise important information affecting the nation, the right to receive and impart information, and consumers’ right to information necessary for their safety and welfare.
Kenya still relies heavily on SMS for mass communication
The directive arrives as Kenya’s communications market becomes more dependent on smartphones and mobile broadband, yet SMS remains a large-scale distribution channel. Data reported by CA and covered by TechTrends shows that Kenya recorded 57.1 billion SMS messages during the 2025/26 financial year, even as SMS traffic declined slightly and smartphone connections reached 52.26 million.
The scale of the mobile network is also substantial. Kenya had 87.99 million mobile SIM subscriptions by June 2026, alongside 79.7 million connected mobile devices. Those figures should not be treated as a headcount because one individual can hold multiple SIM cards, but they illustrate the potential reach available through the country’s mobile networks.
That reach helps explain why SMS remains useful for emergency communications. An alert delivered through SMS does not depend on a particular messaging application or social-media account, and the mechanism can reach both smartphone and feature-phone users. The CA directive therefore places an established communications channel at the centre of the early-warning exercise even as Kenya continues to expand 4G and 5G connectivity.
The role of SMS also sits alongside a changing network landscape. Kenya is phasing down older 2G and 3G infrastructure while operators expand newer mobile technologies, raising practical questions about how emergency communications will remain accessible across different devices and network conditions. The CA directive establishes the obligation to deliver the messages, but does not specify in the letter how the system will handle every possible network or device-level failure.
What the October 2 early-warning simulation will test
The October 2 exercise is intended to test Kenya’s National Early Warning System and the communications processes surrounding emergency notifications. CA’s letter describes the exercise as part of preparations for the El Niño rains and requires operators to facilitate the scheduled test runs.
The document does not provide the full technical architecture of the warning system. It identifies Short Code 1590 as one of the designated platforms, but does not state in the letter exactly how messages will be generated, targeted or distributed, whether the exercise will use national or geographically targeted notifications, or what delivery-time standard operators must meet.
Those details matter because sending an SMS and delivering a useful emergency warning are different operational problems. In a real disaster, networks may face congestion, power interruptions, damaged infrastructure or gaps in coverage. CA has instructed operators to accord priority to emergency communications and ensure timely delivery, although the directive does not set out a specific delivery-time service level.
The Authority has also asked operators to submit their preparedness status, following an earlier September 22 communication. That gives CA a mechanism to establish whether the networks are technically and operationally ready for the exercise and subsequent emergency response.
The directive places telecom networks inside Kenya’s disaster-response infrastructure
The order illustrates the public-safety role that mobile networks can play beyond ordinary voice, messaging and data services. Earlier reporting by TechTrends on the treatment of telecommunications as critical infrastructure highlighted the importance of reliable connectivity for emergency response and other essential services. The CA’s latest directive provides a concrete example of that principle being applied through operator licence obligations.
There is also a useful tension in the technology behind the exercise. SMS volumes are no longer growing in line with the country’s broader mobile connectivity, while smartphone and broadband adoption continues to expand. Yet when authorities need a communications channel capable of reaching a very large number of active mobile subscriptions, SMS remains one of the tools being prioritised.
The immediate test, therefore, is broader than whether a message can be sent. It will show how the Government, CA and mobile operators coordinate when a communications network is being used as part of a public-warning mechanism, including how quickly authorised messages move through the networks and whether subscribers receive them despite normal messaging preferences.
The CA letter does not say that Kenya has created a new nationwide emergency-alert technology, nor does it establish that every subscriber will receive the same message. What it does establish is that the regulator has ordered the country’s mobile operators to remove the normal commercial messaging barriers for authorised emergency communications during the simulation and the stated El Niño preparedness and response period.
For mobile users, the practical implication is straightforward: an authorised emergency or disaster-preparedness SMS may reach their handset even if they have previously opted out of promotional messages or enabled DND settings. For the communications sector, the exercise offers a real-world demonstration of how Kenya’s mobile infrastructure can be mobilised when public authorities need to distribute safety information at scale.
