Why is there no 5G signal icon on my screen?
If there is no 5G indicator:
a) Contact your SIM card operator to check whether 5G service is available.
b) If this issue only occurs in a certain place, move to a location with a strong signal and try again.
Note: You can check network and signal status at “Settings”-> “System” -> “About phone” -> “Status” -> “SIM Status”.
