Sprint is going to axe its "Cut Your Bill in Half" promo. Until further notice, the carrier is offering something different: $50 for "unlimited" talk, text and data for a single line, $80 for two, $100 for three and $120 for four. The company's chief marketing officer Roger Solé described this as a response to customers' apparently overwhelming decision to use its existing unlimited plans. By his count, some 90 percent of subscribers were signed up for the unlimited plans. The aim, Solé says, is to declutter Sprint's service offerings. But honestly, this is Sprint trying to sugarcoat the removal of its deeply discounted plan.
