Mobile Broadband Disclosures
Comcast's Xfinity Mobile and NOW Mobile broadband Internet access services (collectively, “Comcast Mobile Services” or “Services”) utilize Wi-Fi service - both Xfinity WiFi and Wi-Fi provided by other Internet Service Providers ("ISPs"). When not connected to Wi-Fi, the Services utilize our carrier partner's mobile broadband Internet access service network and are subject to its network management practices and controls. The disclosures below reflect, where appropriate, those practices and controls. These disclosures do not describe the practices, characteristics, or terms that apply when our customers are using roaming partner networks. In addition, in certain limited areas, Comcast will use its own licensed spectrum to offload mobile data traffic for certain customer devices.

Comcast Mobile Services strive to provide customers the best experience when using our carrier partner's network. However, an individual user's experience will vary depending upon many factors, including the network (4G LTE, 5G, or 5G Ultra Wideband) the customer is using, the device in use, and the data option the customer has selected.
Certain customers may experience slower data speeds during periods of congestion on our carrier partner's cellular network. Once the demand on the cellular network lessens, your speed will return to normal.
The 4G LTE, 5G, and 5G Ultra Wideband networks of our carrier partner use optimization and transcoding technologies to transmit data files in a more efficient manner to allow available network capacity to benefit the greatest number of users. These techniques include caching less data, using less capacity, sizing video files more appropriately for mobile devices, and optimizing video viewing, which can involve managing video resolution and throughput.
These optimization and transcoding techniques are not applied when a device is utilizing Xfinity WiFi or other Wi-Fi service to transmit data and therefore text, image, and video files will be delivered over Wi-Fi at the native resolution. On Xfinity WiFi, Comcast uses reasonable network management practices that are consistent with industry standards. Additional information on Comcast's Xfinity WiFi congestion management practices is available here. When Comcast Mobile Service customers are connected to other ISPs' WiFi, congestion management practices will vary by ISP.
With respect to customer devices operating on a 4G LTE, 5G, or 5G Ultra Wideband network, the maximum resolutions for streaming video over Comcast Mobile Services are detailed below.
Comcast provides its customers with full access to all the lawful content, services, and applications that the Internet has to offer, subject to our Customer Agreement, Privacy Policy, and other policies discussed in these disclosures. As noted above, we and our carrier partner use video optimization techniques that may affect video resolution and throughput. Comcast reserves the right at all times to intervene to protect the integrity of its Service and network.
You may activate devices that Comcast has certified to be compatible with its network, including devices not purchased directly from Comcast. Information about obtaining a device and device compatibility, including a list of approved devices and their prices, is available here and here.
Depending on the capability of your device, using your Comcast Mobile Services to create a mobile hotspot or tether your device to other connected devices may be permitted pursuant to the terms, conditions, and data pricing options of your Service and subject to the network management practices and controls of our carrier partner.
For all data options, speeds will be subject to the maximum speeds the tethered device receives. See "Price, Data Usage, and Other Fees" below for more information on these data options.
Comcast recognizes that a reliable network must be, among other things, a secure network. We, along with our carrier partner, work to protect the network against outside attacks, tampering, malicious activity, and network events that may disrupt or degrade Comcast Mobile Service customers' ability to use the network.
Our carrier partner blocks a limited number of Internet addresses that are disruptive or malicious and typically persistent, based on analysis and third-party intelligence. Our carrier partner does not block sites based on content or subject, unless the Internet address hosts unlawful content. Our carrier partner regularly reviews and modifies the list of blocked Internet addresses, taking any off the list that are no longer perceived as a threat.
If you would like information about access to a particular Internet site or destination through Comcast Mobile Services, please send your inquiry to bbdisclosures@comcast.net.

- Other Services on the Network
Over Mobile Network. Comcast offers mobile broadband Internet access services to Comcast Mobile Service customers over 4G LTE, 5G, and 5G Ultra Wideband mobile broadband networks. Based on our carrier partner's internal testing and testing commissioned from third-party vendors, Comcast expects customers will experience the following speeds on their Services:
Latency is the time delay in transmitting or receiving packets on a network. Latency is primarily a function of the distance between two points in transmission, but also can be affected by the number and quality of connections to the network or networks used in transmission. With respect to latency for use of real-time data applications, Comcast expects network-to-device (round-trip) latency for Comcast Mobile Services to be between 37-56ms on the 5G Ultra Wideband network (when and where offered), between 42-63ms on the 5G network, and between 51-82ms on the 4G LTE network. Since our service utilizes our carrier partner's mobile network, and is thus subject to its limitations, these expected latency levels may not reflect the actual latency that you experience.
You must be using a 5G device and be within the 5G coverage area to access the 5G, and 5G Ultra Wideband network. You must be using a 4G LTE device and be within the 4G LTE coverage area to access the 4G LTE network. For 5G Ultra Wideband, 5G, and 4G coverage information, click here. Customers with 5G devices will access the 4G LTE network where it is available outside the 5G and 5G Ultra Wideband coverage area. Whether you experience these speeds depends on many factors, including, among others, the type of device, the programs running on the device, your location, and how many other customers are attempting to use the same spectrum resources (including both mobile broadband Internet access and other non-broadband Internet access services that share the network), and subject to the applicable congestion management techniques described above. As noted above, the connection speeds of tethered devices will vary depending on your data option. For all data options, speeds will be subject to the maximum speeds the tethered device receives.
Over Xfinity WiFi. The results above do not reflect the service experienced by customers connected to Xfinity WiFi. Comcast Mobile Services are designed to automatically connect to Xfinity WiFi hotspots when a hotspot is available unless the customer changes device settings to inhibit such functionality. Performance over any Wi-Fi network, including Xfinity WiFi, may vary based on any number of factors, such as, but not limited to, the number of other subscribers trying to use the same Wi-Fi router at the same time, your wireless device, your Wi-Fi receiving antenna, your distance to the Wi-Fi router, attenuation from walls and foliage, and interference from other devices using the same spectrum. Wi-Fi uses spectrum that the FCC has allocated for "unlicensed" use, which means that use of this spectrum is not protected from interference from other devices using the same spectrum in the same geographic area. Therefore, Xfinity WiFi, including any Wi-Fi connections through your home Xfinity Internet service, is provided on a "best efforts" basis. When not connected to Xfinity WiFi, Comcast Mobile Services will attempt to connect over our carrier partner’s mobile broadband Internet access service network. Additional information on Xfinity WiFi is available in our Xfinity Internet Service Performance Disclosures and Xfinity WiFi FAQs.
Comcast Mobile Services use our carrier partner's mobile broadband Internet access service network and share that network with those services and other non-broadband Internet access services that our carrier partner offers. When accessing Comcast Mobile Services via an Xfinity WiFi access point, no services other than broadband Internet access service are delivered via the access point. When accessing Comcast Mobile Services via another Wi-Fi network, users may share those Wi-Fi networks with other services that Comcast does not know about or manage. As such, Comcast cannot predict other services that may share those Wi-Fi networks.
