Alltel, a primarily rural communications and wireless service provider, is
offering its wireless customers a $100 credit toward a new mobile phone
every two years. In an effort to keep customers, Verizon Wireless recently
offered a similar plan. Alltel also announced an "Always Up2Date Guarantee"
to analyze customers' phone use every six months to determine whether Alltel
could offer them cost savings under a different calling plan. Alltel offers
consumer services in 24 states.
