No its not a norm ,however one of my friends told me,if he gives someone his number,, that number is usually not on his name (may be a number on your dads or some old relative) . And keep that number separate ,so that you can switch it off when you want. Never share a number you use at office or for personal number .
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.
