5G

5G is the fifth generation of mobile network technology, offering faster speeds and lower latency than 4G.

5G is the current generation of mobile network technology, rolled out across the UK from 2019. It offers much faster peak speeds (1 Gbps+ in ideal conditions) and lower latency (under 10ms) than 4G LTE.

Real-world speeds in the UK

Typical 5G in a strong-signal area: 200-500 Mbps download. 4G LTE on the same network: 30-100 Mbps. The gap is biggest in cities with lots of 5G spectrum deployed; in rural areas the two are often closer.

5G flavours

  • 5G NSA (Non-Standalone): runs on top of existing 4G core — most current UK deployment
  • 5G SA (Standalone): pure 5G end-to-end — rolling out 2025-2027 across UK networks

Phones that need 5G

You need a 5G-capable phone (iPhone 12+, Galaxy S20+, Pixel 5+). 4G phones still work on Fuse — just at 4G speeds.
