S21 ultra mobile data stops and requires airplane mode on off

[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. This issue is there when I use both the sim cards if I disable one sim card the mobile data works fine. I have done everything switched to esim bought a new sim but problem is still there. Anyone else facing this issue??
