Run it while actually on 5G
Disable Wi‑Fi and confirm your device indicates a 5G connection. A browser cannot independently verify the active cellular radio generation.
Measure high-throughput mobile performance and see whether the connection has the speed, upstream capacity and latency headroom expected for demanding mobile use.
High-throughput mobile speed, latency and hotspot headroom
Measure the connection and get a result designed specifically for this test.
The live measurement connects directly to Cloudflare. Results are estimates and can change with Wi‑Fi, VPNs, device load, server routing and network conditions.
Disable Wi‑Fi and confirm your device indicates a 5G connection. A browser cannot independently verify the active cellular radio generation.
Signal strength, spectrum, tower load, indoor coverage and movement can change results dramatically between locations and times.
If your device falls back between 5G and LTE, run both branches under the same conditions to understand the practical difference.
