Telemarketers can call your home phone and personal mobile phone to solicit you. To start of the new year without those pesky solicitors, sign up for the National Do Not Call List. You can add your home and mobile phone and it's FREE. Once you add your numbers to the list, it makes it illegal for them to call you on those numbers. Make sure you confirm your phone number via email after you register your numbers. This gives them permission to add your numbers to the list.
