Signal reception on s21 ultra is bad.

[Durgeshkapoor]

I'm having this issue where my Mobile stops internet completely and only upload sign is shown in the Lte arrows.then I have to toggle airplane mode off-on and mobile data starts working.Now I have checked my Jio signal which shows-105 dbm 36 dsu in about phone>status information >sim card status. Any one facing this issue kindly tell about your signal strength.
