Yes, Tesco Mobile has an active 4G network across the UK, with coverage continuing to expand. To use 4G on Tesco Mobile, you need a 4G-capable device, a Tesco Mobile SIM on a 4G-enabled plan, and to be within Tesco Mobile's 4G coverage area. Check coverage at the Tesco Mobile APN hub.

How to enable 4G on Tesco Mobile

On Android: Open Settings → Network & Internet → Mobile Network → Preferred Network Type and select the highest available option, such as 4G/4G/3G/2G (auto). On Samsung, this is under Settings → Connections → Mobile Networks → Network Mode.

On iPhone: Go to Settings → Mobile Data → Mobile Data Options → Voice & Data and select 4G. If the option is not visible, your iPhone model or carrier plan may not support 4G on Tesco Mobile.

Tesco Mobile 4G APN settings

The APN settings for 4G on Tesco Mobile are the same as the standard mobile data APN. Your phone should use 4G automatically once it is enabled in your network settings. If 4G is not appearing in the status bar despite being in a covered area, try toggling aeroplane mode, restarting your phone or resetting your APN settings to the Tesco Mobile 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.

Troubleshooting Tesco Mobile 4G problems

4G not showing: Check your plan includes 4G. Ensure your device supports 4G. Verify you are within Tesco Mobile 4G coverage. Go to network settings and set the preferred network type to include 4G.

4G slow: 4G speeds vary by location, network congestion and signal strength. Move to an area with a clearer line of sight to a mast. Ensure no background apps are consuming data. Contact Tesco Mobile if speeds are consistently poor in your area.

4G connected but no internet: Check APN settings are correct for Tesco Mobile. Reset network settings. Try switching to 4G, testing mobile data, then switching back to 4G.
