Do you know a free app can share your number with thousands of Telemarketers?

now you know it but what to do about it?

First be smart about accepting Terms of Use when it comes to apps you’re downloading onto your smartphone. Does a flashlight utility really need access to your call logs?

And, while some telemarketers don’t need it, many do—register your number on the National Do Not Call Registry.

Even better, use a fake or alternate number if you absolutely must sign up for a loyalty program or contest. And there’s simply no reason you need to post your phone number on Facebook or your Google profile. The people who you want to hear from already have your number.

Also, make sure to install on your phone an app that will block numbers from texting and calling you.
