If there is no 5G indicator:
a) Check whether the “5G” function is enabled. Go to “Settings”-> “Cellular network” or "SIM card & mobile network” ->“5G”-> touch the trigger to enable the “5G” function.
b) Contact your SIM card operator to check whether 5G service is available.
c) 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 /tablet” -> “Status” -> “SIM Status”.
Note: This Q&A question is only applicable to devices that support 5G signal connection.
Available settings and menus may vary depending on device model and software version.
