Verizon Wireless subscribers can now change their calling plans within the carrier without having to extend their contracts--all part of Verizon Wireless' "Worry Free Guarantee." Existing Verizon Wireless customers will have the option to change their voice and data calling plans starting October 7. The Worry Free Guarantee program also includes the carrier's 30-day trial period for new subscribers looking to "test drive" the carrier's network as well as a declining early termination fee as a contract runs out.
