Samsung Galaxy A15 5G sim card is not activated after turning the airplane mode OFF

Hi,

We have a brand new Samsung Galaxy A15 5G. when at night I turn ON the Airplane mode and in the morning turning Airplane mode off, that's where we see the prohibited sign :prohibited: instead of the signal strength bar. I have to restart the phone to active the mobile sim card. 

please help. or I have to return the phone.

Why do you put the phone in airplane mode at night? Just put it on do not disturb.

Air plane mode isn't for activation or phone call needs
