If you asked the right qualifying questions and have been listening to the customer overcoming objections should be the easiest part of the sale.  When overcoming objections focus on the positive as much as possible, making negative remarks more often than not leads to a negative customer response (they are mirroring you without realizing it) and that doesn’t get you the yes you’re looking for.

For instance, if the customer mentions they like something about another carrier more your response should be something along these lines “You’re right Verizon does have a reputation for having a great network but with AT&T you’re able to talk and use the phones web capabilities at the same time, and quite frankly I never have issues with coverage on my AT&T phone and you’d be amazing how handy it is to have that functionality with all the great new apps available.”  Remember agree with the customer then point out an additional benefit your product offers.
