Network issue

We understand that your Galaxy S22 Ultra has little or no mobile network signal in certain locations, while the network works normally when you are outside.

This behavior can be related to differences in network coverage and signal strength indoors, as walls and other physical obstacles can weaken the cellular signal. Samsung also recommends checking the network settings and SIM card when experiencing poor signal.

Please try the following:

1. Restart the device and check the network signal again.
2. Go to Settings > Connections > Mobile networks > Network operators and select Select automatically.
3. Go to Settings > Connections > Mobile networks > Network mode and try 5G/LTE/3G/2G (Auto Connect), if available.
4. Remove the SIM card, check that it is clean and properly inserted, then test again.
5. If possible, test another active SIM card in the device to determine whether the issue is related to the SIM or network provider.
6. Reset the network settings from Settings > General management > Reset > Reset network settings. Please note that this will remove saved Wi-Fi networks and Bluetooth connections.

If the device continues to lose network coverage in locations where other phones using the same network have a stable signal, we recommend having the device inspected by an authorized Samsung Service Center to check the device's network hardware.

If the device has already been inspected or repaired by an authorized Samsung Service Center, please continue following up with the same Service Center so they can review the previous service history and proceed with the necessary action.
