Comcast will also be placing a substantial restriction on the use of cellular hotspots, by replacing 4G hotspot speeds with 3G, 600kbps speeds. This can help you save money if you pay By the Gig and take longer to reach the 20 GB threshold if you have the Unlimited data option.
"To help you conserve data, we've established 480p as the standard resolution for streaming video through cellular data", Comcast told customers.
Comcast said that 480p "is consistent with standard unlimited plans across carriers", and that it's making the changes to bring Comcast's offerings in line with the rest of the industry.
After Comcast announced the new throttling policy to its customers, one customer reportedly posted the announcement to Reddit.More news: Apple Working on High-End Airpods, Over-the-Ear Headphones

The option to pay more for 720p video streams won't go live until later this year, according to the email, though the 480p cap will start. If you are already an Xfinity Mobile unlimited customer, you can get in touch with customer support and ask to get your video streaming set at 720p while on the network.
Without net neutrality, Comcast and other internet service providers are now legally able to do things like throttling internet speeds without recourse. During this time period, subscribers will have the option to request upgraded 720p video streams, which they'll receive for free until the billing option is activated. This will be allowed "on an interim basis at no charge", Ars Technica reports. All Xfinity Mobile customers are receiving this email, Comcast confirmed to Ars. Xfinity Mobile will continue to let customers paying by the GB to use their hotspots with 4G data. Almost half of videos that stream on Comcast's mobile service play at 480p today, according to the company.
If you're an Xfinity Mobile customer, what do you think about these changes? Xfinity Mobile is split into two plans: Unlimited for $45 a month or Pay By the Gig for $12 per GB. But with these changes, it's looking less like a steal, and more like the rest of the unlimited data plans on the market - not really unlimited.
