U.S. wireless carrier Sprint has launched a new promotion that aims to ease the financial pain of cellular defectors. Through April 16th, the company will offer a $125 service credit to users that port their number to Sprint from another carrier and sign a two-year smartphone contract. If a smartphone is not in your future, Sprint will offer a $50 service credit to those users porting to a non-smartphone plan. After moving your number over, apply for the credit, and 60 days later an service credit will appear on your wireless statement. The offer is available to those that migrate a line of service from another carrier via Sprint’s online store, phone sales team, or retail locations.
