iPhone Lagging while using Mobile/Cellular Data

Do you have a 3rd party VPN installed, even if you are not using it? If so, delete the VPN profile in Settings/General/VPN & Device Management/VPN, then restart your device. Don't just turn it off; delete the profile. Updates sometimes need to have VPN to be removed and reinstalled. If that fixes it, you can try reinstalling VPN, but probably shouldn't.
If this isn’t applicable, or doesn’t fix it, check with your carrier. You may have gone over the high speed limit if you have one, or your account could not be configured correctly. And how many “bars” do you have for cellular data? If it is 1 or 2 that could be the problem.
