The number of smartphones connected to mobile networks rose to 42.3 million, representing a penetration rate of 80.8%, by the end of March 2025, according to the latest data from the Communications Authority of Kenya (CA).
- •Feature phones have also recorded growth, with connections climbing to 32.6 million, or 62.2% penetration.
- •In total, nearly 75 million mobile devices are active on Kenya’s networks, a reflection of the country’s deepening digital footprint and heavy reliance on mobile technology for communication, commerce, and daily life.
- •While these numbers highlight the vibrancy of Kenya’s mobile sector, they also bring fresh challenges.
With smartphone penetration approaching saturation levels, operators are under pressure to innovate, not just in expanding infrastructure, but in enhancing the quality of service, lowering data costs, and introducing next-generation digital services that meet the evolving needs of consumers.
The rise in device connections is going hand in hand with a surge in usage. Domestic mobile voice traffic hit a record 28.9 billion minutes, up from 27.4 billion minutes the previous quarter, driven largely by strong growth in on-net calls. Meanwhile, SMS traffic rose modestly to 14.3 billion messages, reaffirming the relevance of traditional communication channels despite the dominance of internet-based messaging apps.
The CAK attributes these positive trends to aggressive customer retention campaigns by mobile network operators, as well as continued expansion of 4G and 5G network coverage into more regions of the country. The availability of affordable smartphones, coupled with competitive data and voice packages, has also played a key role in driving uptake.
The rapid growth in connected devices raises concerns about e-waste management, especially as consumers replace older devices with newer models.
Kenya’s mobile future will likely hinge on how effectively the sector can balance sustainability, affordability, and innovation- ensuring the digital revolution benefits all segments of society without creating new environmental or economic risks.
