How do I hide an outgoing phone number on my cell phone bill
Telemarketers and people who do telephone research or charities are not allowed to call any cell phones by law. If they accidentaly call your number, just tell them it's a cell phone and they won't call you again.
When you block a number on your cell phone, you will not receive any calls from that number. You also will not receive any text messages from the number.
Contact your service provider
No, you can only block specific numbers.
You are not able to block any phone number manually from any cell phone. You could call your cell phone carrier and ask them to block the phone number for you. You can also put the contact you wish to ignore in a ignore list where your phone will not ring or vibrate when they try to call or text you.
It is not nearly as common as telemarketer calls to landline phones since it is usually illegal for telemarketers to call wireless phone numbers. It does still happen, though users can register their number with the national do-not-call registry.
