Free Internet Forever: Charter Pitch to Win Mobile Customers

Charter Communications Inc., the company behind the Spectrum cable service, is making an unusual offer to attract new mobile-phone customers: Sign up for four wireless lines and get free home internet service for life.

Customers can obtain four lines and internet service for $120 a month. It includes caveats, of course, such as a cap on data speed, and it only applies to people who transfer lines from a competing carrier. If you cancel the mobile lines, you lose the freebie.
