Comcast’s Xfinity Mobile announced it will begin throttling all of its users’ video streams to 480p resolution and its unlimited customers' personal hotspot speeds to 600 Kbps. The operator added that, later this year, it will allow customers to pay extra to stream video at 720p resolution.  

“We’re making two changes to our service to help us maintain the low price point of Xfinity Mobile,” the carrier explained in a statement to FierceWireless. “First, we’re establishing 480p as the default resolution for streaming video over cellular data on Xfinity Mobile, which is consistent with standard unlimited plans across carriers. It’s important to note that this change won’t impact video resolution when using Wi-Fi, where customers will continue to be able to stream in HD. Second, we’re setting personal hotspotting at 3G speeds for all Unlimited customers, which will allow customers to continue to do many of the things they enjoy doing online. Our By the Gig data option will continue to deliver 4G speeds for all data traffic.”
