A mobile hotspot (also called tethering or personal hotspot) lets you share your your mobile data connection with other devices via Wi-Fi, Bluetooth or USB. This is useful when you need internet on a laptop or tablet but have no Wi-Fi available.

Fixing hotspot connected but no internet

Go to Settings → Network & Internet → Hotspot & Tethering → Wi-Fi Hotspot. Toggle it on. Set a name (SSID) and password for your hotspot. Other devices can then find and connect to it in their Wi-Fi settings. On Samsung, go to Settings → Connections → Mobile Hotspot and Tethering.

Tethering vs hotspot — differences explained

Go to Settings → Mobile Data → Personal Hotspot. Toggle Allow Others to Join on. Set a Wi-Fi password. Your hotspot name defaults to your iPhone's device name, visible to nearby devices in their Wi-Fi list.

Troubleshooting hotspot disconnecting frequently

Your hotspot uses the same APN settings as your mobile data connection. If hotspot is not working, first check that your main mobile data is working, then verify your your mobile network APN settings are correct. Some plans restrict hotspot usage — check your your mobile network plan at the UK APN Hub to confirm tethering is included.

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 your mobile network hotspot problems

Hotspot connected but no internet: Restart the hotspot. Check APN settings. Make sure mobile data is working normally on your phone first.

Personal Hotspot missing on iPhone: Go to Settings → Mobile Data → Mobile Data Network and ensure the APN field is filled in. Restart your iPhone.

Slow hotspot speeds: Move to an area with stronger your mobile network signal. Reduce the number of connected devices. Check your plan has sufficient data remaining.
