How to test 5G speed accurately
- 1Turn off Wi-Fi so your device uses mobile data for the test.
- 2Check your status bar shows 5G rather than 4G/LTE.
- 3Stand still — moving between cells mid-test skews the result.
- 4Run the test a few times; mobile speeds vary with signal, congestion and location.
Why 5G speeds vary so much
5G comes in flavours. Low-band 5G reaches far but is only modestly faster than 4G. Mid-band (the most common good 5G) delivers a few hundred Mbps. High-band mmWave can exceed 1 Gbps but only over short line-of-sight distances. Your result depends heavily on which band you're on, how far you are from the tower, and how many people share the cell.
5G vs home broadband
Run this test on 5G and again on your home Wi-Fi to see which is faster where you are. Fixed 5G home internet can rival fibre in strong-signal areas but is more variable.
