No signal, Wi-Fi or Bluetooth on your phone? Reset network settings
Network problems usually come from settings, the router or the SIM card, not a broken phone. Start with the simplest steps.

- Time
- 10–20 minutes
- Repair shop, if nothing helps
- 110–480 zł for diagnostics and repair
A network settings reset removes saved Wi-Fi passwords and Bluetooth pairings. Your photos and apps stay. Keep your Wi-Fi password handy, because you will have to enter it again.
Step by step
Turn on Airplane mode and turn it off after a minute
This refreshes the radio connections. Then restart the phone.
Check whether the router is the problem
Restart the router (unplug it for 30 seconds) and check whether other devices connect to the network. If they do not, the problem is with the router or your provider.
Pair Bluetooth again
Remove the device from the paired list and connect it again.
Check the SIM card
If there is no signal, switch off the phone, take out the SIM card and put it back in. Check that the network is not set to manual and switch it to automatic.
Forget the Wi-Fi network and reconnect
Remove the network from the saved list and enter the password again. This fixes problems after a password change or a router update.
Before the network reset
Warning: a network settings reset removes saved Wi-Fi networks with their passwords and paired Bluetooth devices. Write down any passwords you need.
