Galaxy M30s after update to Android 11 | Facing very slow speed internet connection Issue

[TharikMohamed]

Hello Sir,

I face a very slow speed internet connection even in full network coverage.
Then I changed the same Sim to another handset, no problem with that phone.

Then I put another Sim to my m30s, the same slow speed problem exists there. 

Then Samsung expert remotely accessed my device and did something,but no use

Then I have reseted my phone, no use
