Verizon’s new data plans announced on Tuesday are expected to be followed by others in the industry as wireless firms focus their attention on charges for Internet data, according to analysts... The new plans, to launch June 28, are expected to motivate families to get more devices onto a single plan, according to analyst Craig Moffett, of Sanford C. Bernstein. That business strategy benefits the biggest wireless carriers — AT&T and Verizon Wireless — and presents new problems for competitors trying to chip away at those firms’ dominance.
