It is the sound of modern Kenyan frustration: a sudden silence in the middle of a business deal, a family check-in, or an emergency call, followed by the frantic, futile query—“Hello? Can you hear me?”

For millions of subscribers, this digital hiccup is no longer just an annoyance; it is a statistical certainty. A damning new survey by the Communications Authority of Kenya (CA) has confirmed what many have long suspected: Airtel Kenya’s network is the most prone to dropping calls among the country's major mobile operators, effectively taxing its users’ patience in exchange for lower tariffs.

The Numbers Don’t Lie

The CA’s latest Quality of Service report paints a stark picture of the disparity in Kenya’s telecommunications duopoly. While Airtel has aggressively marketed itself as the affordable alternative to the market leader, the data suggests that reliability remains a premium commodity.

• The 19.4% Threshold: Nearly one in five Airtel callers experiences more than five outages for every 100 calls made.
• The Safaricom Gap: In contrast, Safaricom users fare significantly better, with only 7.4% reporting a similar frequency of dropped calls.
• The Jamii Factor: While Jamii Telecommunications actually recorded a higher outage rate (30.1%), their smaller mobile market share leaves Airtel as the primary culprit affecting the mass market.

“These figures indicate that while a fair share of Airtel users enjoy reliable conversations, many still face frequent disruptions,” the CA noted in its report. For a trader in Gikomba or a boda boda rider in Kisumu, where every second of airtime translates to shillings, these disruptions are not just technical failures—they are economic losses.

Infrastructure vs. Affordability

The root cause of these outages appears to be a lag in infrastructure investment relative to subscriber growth. The CA has previously flagged aging Base Transceiver Stations (BTS) and sparse deployment in rural areas as critical bottlenecks. While Safaricom has continued to densify its network, accounting for 61.2% of total call time, Airtel’s grid seems to be buckling under the weight of its own competitive pricing strategy.

“Cheap is expensive if you have to make the same call three times,” notes James Mbugua, a telecommunications analyst in Nairobi. “Airtel’s strategy has been to undercut on price, which is vital for the Kenyan wallet. But if the network cannot sustain the traffic, that value proposition collapses.”

Regulatory Red Flags

The regulator is not merely observing from the sidelines. Section 23 of the Kenya Information and Communications Act mandates that telcos meet strict Quality of Service (QoS) standards or face significant fines. The CA has issued warnings to Airtel in the past regarding poor coverage, and these new figures pile pressure on the telco to shore up its technical backbone.

For the Kenyan consumer, the choice is becoming increasingly binary: pay a premium for the stability of the market leader, or accept the gamble of a dropped line for a lower rate. Until the infrastructure gap closes, the most expensive call remains the one that never finishes.
