No data caps.

Charter Communications is now heavily advertising the fact its Internet service “has no data caps,” in an attempt to leverage customers away from AT&T DSL (150GB cap) and AT&T U-verse (250GB cap).

Charter quietly shelved its softly enforced usage caps several months ago and is now using its cap-free experience as a marketing tool to convince customers to switch from AT&T and other phone company broadband options that often include usage limits.

“They used it with me to convince me to drop U-verse for Charter,” writes Stop the Cap! reader Jennifer in Tennessee. “I hate usage caps.”

Charter is also using its cap-free broadband as a key argument in favor of its merger deal with Time Warner Cable and Bright House (which have no usage caps either).

“Charter’s slowest speed tier (60Mbps downstream) is considerably faster and less expensive than TWC’s comparable tiers, with no data caps or usage based pricing,” Charter argued in its merger presentation this morning.

AT&T has unevenly enforced usage caps on its DSL and U-verse services. A standard overlimit fee of $10 for each 50GB applies, but only in some markets.
