Many Kenyans have experienced a frustrating situation where a phone displays a 4G connection, yet a webpage takes too long to load, a video keeps buffering, or an online service fails to respond.
A new report by the Internet Society Kenya (ISOC Kenya) shows that the problem may not necessarily be linked to the speed of the mobile connection.
The ISOC Kenya H1 2026 Technical Report found that Kenya’s average mobile download speed stood at 45.38 Mbps, which it described as acceptable.
However, the country recorded a mobile network consistency score of just 32 out of 100 and an equally low responsiveness score of 32 out of 100.
As a result, Kenya’s overall mobile network subscore stood at 43 out of 100, despite the relatively strong average download speed.
“Measured mobile download speeds average 45.38 Mbps, which is acceptable. Yet Kenya’s mobile network subscore is only 43 out of 100, pulled down by consistency and responsiveness rather than raw speed,” says the report.
Why a Fast Connection May Still Struggle
The findings point to a difference between how fast a network can download data and how consistently it delivers that service.
Download speed measures how quickly data can be received over a connection. However, consistency reflects how reliably the connection maintains performance, while responsiveness concerns how quickly the network reacts to a user request.
This means a connection can show a good download speed during a test but still provide a poor experience when performance fluctuates or responses take longer than expected.
According to the report, these factors can affect everyday activities such as opening webpages, using online platforms, accessing cloud services, making mobile banking transactions, and holding video calls.

The 4G symbol on a phone mainly shows that the device is connected to a 4G network. It does not guarantee that the connection will always maintain the same performance.
Similarly, strong signal bars do not necessarily mean a user will get the highest available download speed or a fast response from an online service.
This helps explain why a user may have a strong 4G connection and enough mobile data but still experience delays when accessing a particular website or service.
Kenya’s Mobile Internet Use Continues to Grow
The network performance findings come as mobile internet use continues to expand in Kenya.
The report states that active mobile subscriptions reached 84.1 million in the quarter ending March 2026, representing mobile penetration of 157.7 percent.
By the end of June 2026, the number of subscriptions had increased to 87.99 million, equivalent to about 165 percent penetration.
The figures exceed the country’s population because one person can have multiple mobile subscriptions, including different SIM cards or lines used for different purposes.
Smartphones accounted for 65.6 percent of connected devices, showing the growing role of smartphones in accessing internet-based services.
Mobile broadband consumption also remained high, reaching 800 million GB in the first quarter of 2026.
The report found a significant difference in data consumption between standard mobile broadband users and 5 G users.
Standard mobile broadband users consumed an average of 15.1 GB, while 5G subscribers recorded average consumption of 53.5 GB.
The higher usage among 5G subscribers reflects the growing amount of data being consumed through faster mobile connections and internet-based services.
4G Access Is Widespread
According to the report, 98 percent of the population has access to at least one 4G-capable device, while 32 percent have access to a 5G-capable device.
The widespread availability of 4G means that the issue facing users is not necessarily whether they can connect to a modern mobile network.
Instead, the findings point to the quality and reliability of that connection once a device is connected.
A user in an area with 4G coverage may still experience slow or inconsistent service, depending on factors that affect network responsiveness and consistency.
The same applies to 5G. Although the technology offers higher potential speeds, access to a 5G network does not automatically guarantee that every online service will respond quickly.

Kenya’s Internet Resilience Score
The report also assessed Kenya’s broader internet resilience using the Internet Resilience Index.
Kenya recorded an overall score of 53 out of 100, matching the global average of 53 and remaining above the African average of 41.
However, Kenya’s score on the performance pillar was 50, compared with a global average of 57.
The performance assessment considers factors related to the quality and efficiency of internet connectivity, making it relevant to the experience users have when accessing online services.
The findings show that Kenya’s challenge is not simply whether people can access mobile internet or how high a network’s advertised or measured download speed is.
The quality of the connection also depends on how consistently the network performs and how quickly it responds to users’ requests.
What the Findings Mean for Mobile Users
For ordinary users, the difference between speed, consistency, and responsiveness can show up when using services that require more than simply downloading a large amount of data.
A webpage, for example, may require several separate requests before all its text, images, and other elements appear. If the network responds slowly or its performance keeps changing, the page can take longer to load even when the connection has a relatively high download speed.
The same issue can affect online payments, social media platforms, video calls, and other services that depend on a stable connection.
The ISOC Kenya findings show why the 4G indicator on a phone should not be treated as a guarantee of a smooth internet experience.
Kenya has widespread 4G access and growing 5G coverage, while average mobile download speeds remain relatively strong.
However, the report’s lower scores for consistency and responsiveness show that how reliably and quickly a network responds can matter as much as how fast it can download data.
