Verizon offers a variety of prepaid cellphones. If you purchased one of the cheaper phones, you might wonder why anyone would want to keep it when Verizon offers free phones when you sign a contract. But not all prepaid phones are cheap. Verizon also offers Droid, Vortex, Blackberry and similar phones that can be used with its prepaid plans, most of which cost several hundred dollars. If you fall into that group, you may not want to change phones when you sign a contract.
