Dial *67. This code will block your number so that your call shows up as an “Unknown” or “Private” number. Enter the code before the number that you‘re dialing, like so: *67-408-221-XXXX. This may work on cell phones and home phones, but it won’t necessarily work on businesses.
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.
