Feeling heat from the competitors that had
eliminated data
overage charges, Verizon last year introduced its own set of plans without the hated
fees and saw more customers than expected switch.
Many of Verizon's new features, including data rollover,
eliminating high roaming
fees in Canada and Mexico, and the end of
overage charges (instead slowing the speed of data after an allowance runs out), were pioneered by T - Mobile.
