The iPhone doesn’t actually provide a way to block phone numbers. You can tap “Decline” when the phone rings, but you can‘t just tap a “Block” button to keep someone from calling anymore. … For that, your best bet is to give the number a silent ringtone, which won’t block the number but will keep it from bothering you.
When you call a dead phone does it ring?
Answer: A: With a dead battery it should not ring but it should go to voicemail directly.
