How many lines do you have? If you are already on a family share plan you can always add a line and switch the phone to your number so you end up getting the discounted price but you pay $9.99 a month for that new line which isn't too bad.
Now, if you are willing to get a new number.. If you do as above, add a line and get a smart phone with the $30 unlimited data plan, verizon will actually give you a credit for 9.99 per month as long as that smartphone is on the new line. This will mean you can keep your basic phone on your current number and get a smartphone with another number and your bill will not change other than your data plan.....its kinda confusing but if you pop into your local verizon they can tell you about the smartphones talk free promo that just hit.
