Kenya reached 88 million active SIMs by 30 June 2026, equal to 165% of the population. It is a striking number, and for anyone who sends SMS it is easy to misread. A SIM count measures lines that recently earned revenue. It does not count people, and it does not count people you can reach.
Key findings
What “active” really counts
The Communications Authority treats a subscription as active if it generated revenue in the last three months. Reports of its data note that the measure tracks service availability, not unique users. One person with two or three SIMs counts two or three times, which is how penetration passes 100%. About 96.5% of lines are prepaid, so a line can come and go with little friction.
The jump in early 2026 needs care too. The regulator pointed to operators’ win-back campaigns, and Tech-ish judged that much of the rise was reactivation rather than new customers. That is its reading, not a measured split, but it fits the numbers: 5.7 million added in one quarter, against almost no movement in the quarter before.

Texts per SIM fell. Part of that is arithmetic.
Reported SMS per subscription dropped from 61 to 55 a month. That looks like people abandoning texting, but the bottom of the fraction changed as well. Our arithmetic: 13.98 billion messages over the 78.39 million lines of December gives about 59 a month; over the 84.1 million lines of March it gives about 55. So roughly two-thirds of the fall comes from more SIMs, and about a third from fewer messages. Volume did fall 2.7%, so the decline is real. It is just smaller than the per-SIM figure suggests.
Traffic also sits unevenly across networks. Safaricom holds 68.9% of SIMs but carries 93.96% of SMS. The figures available do not split person-to-person from business messages, so nobody should read that gap as a pure measure of bulk SMS. Our State of SMS in Kenya report covers the wider market.

What this means for your sender list
A larger national total does not make your list larger or healthier. If win-back drives the growth, some lines return for one offer and fall quiet again. Numbers on your list can also stop being read long before they stop counting as active. Delivery reports from your own sends will tell you more than any national figure. The calculator below uses example numbers; replace them with yours.
What are dead numbers costing you?
Example inputs, not benchmarks. Use your last send’s delivery report.
The channel decision is a separate question. SMS versus WhatsApp in Kenya compares the two, and with 28.5 million feature phones still in use, USSD remains relevant for services that must reach them.
Methodology
This report relies on press reports of Communications Authority data. We could not read the authority’s own PDF, so these figures have not been checked against its tables. We left out broadband subscriptions because sources conflict, at 52.9 million and 62.6 million. We did not find an SMS volume for April to June 2026. The per-SIM split is our own arithmetic on reported figures and is approximate. The calculator is illustrative.
FAQs
How many mobile subscriptions does Kenya have?
Reports of Communications Authority data put active subscriptions at 88 million on 30 June 2026, equal to 165% of the population.
Why is mobile penetration above 100%?
Because it counts active SIMs, not people. Anyone holding more than one active SIM is counted more than once.
Is SMS use falling in Kenya?
Yes, modestly. Volume fell 2.7% quarter on quarter to 13.98 billion in January to March 2026. The steeper fall in texts per SIM is mostly caused by the SIM count rising.
