Cell phone numbers are no longer private. Your cell phone number was likely made public and available to telemarketers last week.
Depending upon your cell phone service plan, you may be charged for calls from telemarketers. If you want to block telemarketing calls to your cell phone, there is a federal "DO NOT CALL" list for cell phones.
It only takes a minute of your time to register your cell phone number, and it will block your number for five (5) years. You must call the following number: 888-382-1222, ONLY from the cell phone number that you want to register. The registration will not work if you call from a different phone number.
