Found a fix for the iOS 27 lag on my phone. It’s the VPN. Delete the VPN and check, mine seems to be working perfectly fine without the VPN, no connection drop, no calls on data drop, browsing and loading speeds have increased like before I installed iOS 27. Then reinstall the VPN and check again.
iOS 27 network issue FIX.
