How to protect privacy of telephone and protect from unknown callers

Many cell phone owners have experienced an unknown number calling their phone, with no message to key them in to who called. Even though this is most likely harmless, in some cases this number keeps calling, which can be quite frustrating. Then how to protect the privacy of your cell phone and protect your cell phone from unknown callers?

How to protect the privacy of your cell phone:

Do not publish your cell phone number

This step may seem obvious but you would be surprised at the number of people who give out their cell phone number inadvertently. Do not share your cell phone number, for example, when you enter a contest or fill out a survey. Most contests are designed to compile names, addresses, emails, and telephone numbers so that they can be used by or sold to telemarketers. Also, do not use a cell phone to complete online purchases. Your number may end up with a company telemarketer. If a cell phone is the only phone number that you have, check the online vendor's privacy policy.

Block your cell phone number from being transmitted

There are two ways to block your number from being transmitted. The first way to prevent your number from being sent is to preface the number that you are calling with "*67". This prefix allows for per-call blocking. So, to dial the number (123) 555-1212, you would dial: *671235551212. This feature is usually called "Per call blocking" or "Selective blocking". The second way to block your number is to order per line blocking from your cell phone provider. Per line blocking will always prevent your number from being displayed on a caller ID device. It will NOT BLOCK YOUR Number If you DIAL 911 or if you call an 800 Number. If you want to show your number, dial "*82" and then the number you want to call.

Protect your cell phone from unknown callers:

Conduct a reverse cell phone number search, according to Yahoo. This way, the individual can find out if the anonymous caller is a predator, telemarketer or simply someone who has mixed up a phone number. This can be done online-but users should make sure to choose a credible site, which will likely require a fee.

Ask to be added to private DNC lists-Most companies, survey firms and charities have an internal Do not Call list. When you get a call from such an organization, request that your mobile number be placed on their list. Reputable groups, even ones with which you have an established business relationship and therefore the right to phone you, will typically comply with your request.
