Average Internet Speed in Tanzania

Internet in Tanzania: what the data shows

At a median 4.7 Mbps download, Tanzania sits near the back of the field: #112 of 119 ranked countries, well under half the global median of 33.9 Mbps. The world's fastest median belongs to the United States at 144 Mbps, more than 30× the speed measured here.

Uploads keep pace with downloads (5.0 vs 4.7 Mbps): connections here are balanced, just not fast. Median latency is 206 ms. That is on the high side: pages and video still load, but calls, gaming and screen sharing carry a visible delay.

Among providers with enough measured tests, Airtel Tanzania leads at 3 Mbps.

Desktop and mobile tests land at the same 5 Mbps median, so the experience translates directly across devices; mobile accounts for 45% of tests. By operating system, Windows devices record the quickest median (5 Mbps) while Android sits at 4 Mbps, usually a proxy for the networks and hardware each platform rides on rather than the software itself.

Tests from Tanzania most often reached the London test server (30% of the top-server mix), so the figures reflect the routes everyday traffic actually takes. Every number on this page is a median of single-stream browser tests from the H1 2026 window: Real-World Speed, measured on the open internet rather than inside an ISP's own network. It reads lower than peak-rate tests by design, and every country is measured with the same ruler.
