S21 ultra mobile data not working.

[Durgeshkapoor]

I am facing this problem with my s21 ultra 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 again.Even after today's update the issue is not resolved. Does anyone have any solution other than saying use single sim because I have not purchased this phone to use it according to samsung's convenience. 

Will January security update solve this problem???
