UK mobile networks do offer 5G, with coverage growing steadily. To use it, a 5G-capable device, a 5G-enabled SIM plan, and being within coverage are all needed — check the UK APN Hub for coverage details.

Checking if your phone supports your network 5G (Why Is My 5G So Slow)

On Android: Open Settings → Network & Internet → Mobile Network → Preferred Network Type and choose 5G/4G/3G/2G (auto), or the highest available. On Samsung, this sits under Settings → Connections → Mobile Networks → Network Mode.

iPhone: Settings → Mobile Data → Mobile Data Options → Voice & Data, then select 5G. A missing option usually means the device or plan doesn't support 5G there.

Setting up your network 5G on Android and iPhone

There's no separate APN for 5G; it uses the standard mobile data settings and activates automatically once enabled. If it's not appearing in a covered area, try aeroplane mode, a restart, or resetting the APN to defaults.

💡

Fastest way to apply new APN settings

After saving, turn aeroplane mode ON for 10 seconds, then turn it OFF. This forces an immediate network re-registration — quicker than a full restart and equally effective.

When your network 5G drops back to 4G — and how to fix it

No 5G appearing: confirm the plan includes 5G, the device supports it, coverage is available, and the preferred network type includes 5G.

Slow 5G usually comes down to location, network congestion or signal strength — try moving for a clearer mast line of sight, check background data use, and contact support if it stays poor.

If 5G shows connected with no data, verify the APN, reset network settings, or toggle between 4G and 5G to test.
