I just activated the Apple iOS Bedtime and Sleep features for my iPhone and Apple Watch.
But you may notice one thing: once your Sleep time starts, your iPhone stops ringing for incoming calls.
So here is how to turn off the silent incoming call feature…
Step 01: Go to your settings app on your iPhone
Step 02: Navigate to Settings > Do Not Disturb > Phone > Allow Calls From > Tap on Everyone or All Contacts
In Step 02 you can choose your Favourite Contact list or Groups > All Contacts (This will enable notification for all calls from people present in your address book)
Hope it helps,
Thanks & Regards
