Just one month after introducing the iPhone, Verizon Wireless confirmed on Monday that it will stop offering unlimited data plans to iPhone and other wireless smart phone customers this summer and will instead adopt a tiered pricing strategy that charges customers according to the amount of data they consume. In enacting the new pricing policy, Verizon follows in the footsteps of rival AT&T which, last June, eliminated unlimited data plans for all customers except for those already under contract. (Currently, AT&T customers may choose a $15 rate plan that provides up to 200 megabytes of downloads per month or a $25 plan that covers up to 2 gigabytes of data monthly.) Although Verizon first offered its iPhone customers the company’s standard smart phone plan that allows for unlimited data downloads at a monthly rate of $30, Verizon Chief Financial Officer Fran Shammo told analysts at a technology conference that the unlimited data offer is “not a long-term solution.” Shammo offered no details on the anticipated price range of the new data offerings and the amount of data covered by each but noted that “we have a very big opportunity . . . because 67 percent of our customers [have] either feature phones or multimedia phones.” As such, Shammo observed: “we see the potential of our customer base spending in the $30 to $50 range.” Verizon has also said it is considering limiting the download speeds of customers who are among the top 5% in terms of data consumption, in areas and at times when such consumption risks jamming the carrier’s network.
