Check signal coverage
First, check the signal coverage to ensure that your area has good 4G or 5G network coverage. Only when the signal is well covered can the mobile phone receive the signal normally.
View mobile phone network settings
Secondly, check the mobile phone network settings and confirm that the correct network operator and mode are selected. If the settings are incorrect, the mobile phone will not be able to connect to the network normally.
Check SIM card
If there is something wrong with the SIM card, please re-insert or replace it. Sometimes, the SIM card may break down, causing the mobile phone to fail to receive signals normally.
Restart the phone
In addition, restart the phone to ensure that no applications that interfere with the phone signal are running. Sometimes, the mobile phone may have a software failure, resulting in poor signal reception.
