Fibre vs mobile data: which is better for WFH in Nairobi?

If you are working from home in Nairobi, the connection you choose will quietly shape every meeting, every upload, and every late-night deadline. Mobile data is convenient because it travels with you, but for full-time remote work fibre to the home is almost always the better fit, and the gap is widening as Kenyan offices lean more heavily on video, cloud apps, and large file transfers.

Speed and stability are the first divider. Mobile networks share spectrum with thousands of nearby users, so your real throughput drops sharply during peak hours, especially in dense suburbs. A typical home fibre line gives you the same advertised speed at midday and at midnight, and upload speeds are dramatically higher, which matters for video calls, screen sharing, backups, and pushing code.

Cost per gigabyte is the second divider. A one megabit wobble on Zoom can chew through bundles in minutes. Most remote workers using mobile data alone end up topping up several times a week, which works out far more expensive than an unlimited home fibre subscription. Once you add streaming, family devices, and smart home gear, mobile data becomes uneconomic very quickly.

Latency matters too. Mobile latency is variable and spikes when towers are congested. Fibre latency in Kikuyu and the wider Nairobi area is consistently low, which makes voice calls clearer and online tools feel instant.

Where mobile data still wins is mobility, short stays, and as a backup. Many of our customers in Kikuyu Town use fibre as their primary line for work and keep a small mobile bundle for travel and outages. If your week involves video meetings, shared documents, and any kind of cloud-heavy workflow, fibre is the foundation, and mobile data is the safety net rather than the main tool.
