Comcast wireless service now nationwide—and throttling customers after 20 GB of data usage

Comcast claimed most of its customers are saving 30% on their monthly wireless bills since switching to Xfinity Mobile service. 

Comcast will start throttling users of its new wireless service once they exceed 20 gigabytes of monthly usage

That was one of the tidbits of information the cable company revealed and reiterated today while announcing that Xfinity Mobile is now available across its national footprint. 

“Now that we’re available across all of our distribution platforms, including our retail locations in all of our markets, we look forward to introducing even more customers to Xfinity Mobile,” said Greg Butz, president of Xfinity Mobile, in a statement.

The service is built on a wholesale agreement with Verizon, with Comcast using the No. 1 wireless operator’s own marketing language to tout what it calls “the nation’s largest and most reliable 4G LTE network." Comcast also said that the other underpinning of the service, the No. 1 cable company’s public Wi-Fi network, now includes 18 million hotspots. 

Comcast claimed most of its customers are saving 30% on their monthly wireless bills since switching to Xfinity Mobile service. 

The cable operator did not, however, reveal how many subscribers have signed up for the service since it began its rollout over the spring. 

Comcast did say that around 25% of its customers are splitting the service’s two different billing options among their various lines. The “By the Gig” plan allows customers to pay $12 per gigabyte of shared cellular data across all lines each month.

Meanwhile, despite the 20 GB throttling threshold—standard among wireless operators—Comcast is offering what it calls an “Unlimited” option, which requires a $45 monthly fee for up to five lines of uncapped usage.
