I had so many phone calls that i went and bought a sentry phone blocker from amazon.Com for 29.00 dollars, and it has been a blessing, what you do is when they call see if they leave a message, if not i hit the block button hold it down until it says done, and when they try to call back i get one ring and its deleted evertime. When you get a call from your friends after talking to them. You hit the accept button hold it down until its say s done, some times the 1-800 numbers might be a good number, so i answer and if its a bad number i hang up and hit the block button until it says done, if you think like a # 1-651 pops up and i hit the block button and i found out it was my sister back east, what i did was go to the delete button with her phone # on the screen, hold it down until it says done and if she calls back i reconize it, i then hit the accept button, its been a life saver, i now have almost 4oo blocked calls that i dont have to worry about and i 50 saved calls, i hope this will help thanks have a blessed day
