The network architecture providing dual connectivity could result in instances where your device indicates a 5G connection even though you are temporarily utilizing only 4G LTE. As 5G technology develops, devices will be able to experience direct and continuous 5G in more places. If your data plan features a designated allotment of high-speed data, data used by certain speed measurement applications will not count against that high-speed data allotment to provide accurate and reliable information about network performance without consuming large amounts of your data.
See the full list here. If your data plan includes data use at reduced speed after you have used your plan's monthly allotment of high-speed data, your data speed will be limited typically to 64 kbps or kbps for the remainder of your billing cycle once you have used your allotted high-speed data.
The results from some speed measuring applications may show current network speeds, rather than the reduced speed that is currently available to you. Speed measurement applications other than the ones listed here will show your reduced speed. If you use speed tests other than the ones listed here prior to reaching your monthly high-speed data allotment, use of those applications may count against your data allotment.
We engineer our network to provide consistent high-speed data service, but at times and at locations where the number of customers using the network exceeds available network resources, customers will experience reduced data speeds. To provide the best possible experience for the most possible customers on their T-Mobile-branded plans, we implement network management practices on a content-agnostic basis, such as caching less data, prioritizing data usage of non-Heavy Data Users, and video optimization.
These practices do not discriminate against offerings that might compete against those offered by T-Mobile or any T-Mobile affiliate on the basis of such competition. For additional information on network practices, see the discussion below in Network management for extremely high data usage and tethering and How does T-Mobile address network priority for its plans and brands?
T-Mobile uses streaming video optimization technology. Streaming video optimization improves overall data usage management of the network, resulting in greater network speeds and throughput for other customers using data because less network payload is dedicated to video.
For customers on limited high-speed plans, optimization also helps customers stretch their high-speed data while streaming video. For video that is not self-optimized by the video provider, we adjust the delivery rate for streaming video, which causes the video to be delivered in lower resolutions and to use less data.
Video optimization occurs only for data streams that are identified by our packet-core network as video or where the video provider has chosen to establish protocols to self-optimize its video. Some videos, like those consumed via VPN or while tethering, may be difficult to identify as video and therefore cannot be optimized. The streaming video optimization process applies to content identified as video regardless of the content itself or the website that provides it. While many changes to streaming video files are likely to be indiscernible, the optimization process may impact the appearance of the streaming video as displayed on a user's device.
However, T-Mobile offers content providers a way to opt-in to a protocol to help identify video downloads to ensure they are not treated as streaming video. Video streaming optimization, when connected to the cellular network, delivers a DVD-quality up to 1. HD or Ultra HD , which is better suited for larger screens. Video optimization is not applied when a device is using Wi-Fi to connect to a non- T-Mobile network.
Customers on our Magenta plan, where DVD-quality video optimization is always enabled, may choose to activate and enable a feature or plan where video streams at speeds that provide up to UHD video capability max 4K , in the United States, e. Some of our customers are on data plans which include video optimization as a customer-controlled feature called "Binge On," which customers may choose to disable and re-enable at any time.
Some video providers may choose to opt-out of the Binge On program, see listing. Some of our plan options feature a customer-chosen high-speed data allotment with reduced speeds on our network after the high-speed allotment is exhausted, so customers can choose the combination of high-speed data and price that is right for their needs.
Unlimited high-speed data customers do not have a specific high-speed data allotment on their device, however, and customers on some limited high-speed plans may have extremely high data usage under certain circumstances, including if their plan enables access to significant amounts of data that does not count against their high-speed data allotment. While T-Mobile continues to expand its network capacity, at this time, some network management for these scenarios is required, because very heavy data usage at times and places of competing network demands can affect the network performance for other customers.
To provide the best possible experience for the most possible customers on their T-Mobile -branded plans, and to minimize capacity issues and degradation in network performance, we manage significant high-speed data usage on the vast majority of our plans through prioritization. At the start of the next bill cycle, the customer's usage status is reset, and this data traffic is no longer prioritized below other traffic. Customers who use data in violation of their Rate Plan terms or T-Mobile's Terms and Conditions may be excluded from this calculation.
Data features that may not count against the high-speed data allotment for some plans, such as certain data associated with Music Freedom, or Binge On, still count towards all customers' usage for this calculation. Smartphone Mobile HotSpot tethering data is also included in this calculation.
Data used for customer service applications, such as the T-Mobile My Account app does not count towards customers' usage for this calculation. To help avoid application of this practice, and reduce mobile data consumption, customers can set automatic updating of apps, podcasts and file downloads to run off Wi-Fi making sure to connect to Wi-Fi to update applications and system periodically.
Similarly, while we permit tethering pursuant to the terms, conditions and allotments of your data plan, significant Smartphone Mobile HotSpot tethering usage can affect on-device network performance for all customers.
To ensure the best possible on-device experience, and to minimize capacity issues and degradation in network performance, we prioritize on-device data except that of our mobile internet plans 30GB or higher offered after December 12, , our Project 10Million and some other education-focused mobile internet plans, home broadband, and Heavy Data Users, as described above over tethering data at times and at locations where there are competing customer demands for network resources, which may result in slower tethering speeds.
Where the network is lightly loaded in relation to available capacity, a customer whose data is prioritized higher than other traffic will notice little, if any, effect from having higher priority. This will be the case in the vast majority of times and locations. Customers may notice reduced speeds in comparison to customers with a higher priority during network congestion. At times and at locations where the network is heavily loaded in relation to available capacity, these customers will likely see significant reductions in data speeds, especially if they are engaged in data-intensive activities.
Customers should be aware that these practices may occasionally result in speeds below those typically experienced on our 5G or LTE networks, including a greater likelihood of reduced speeds in the lower end of the speed ranges. Depending on the extent of network congestion, these customers may notice more frequent impacts to some video streaming, file downloads, and other high-bandwidth activities.
T-Mobile constantly works to improve network performance and capacity, but there are physical and technical limits on how much capacity is available, and in constrained locations the frequency of heavy loading in relation to available capacity may be greater than in other locations.
When network loading goes down or the customer moves to a location that is less heavily loaded in relation to available capacity, the customer's speeds will likely improve.
You can check your data plan usage at any time by signing in to my. Your total "on-network data" is the number used for purposes of heavy data usage prioritization. Customers select how much high-speed data they receive under their service plan. Certain features, such as Music Freedom, some Binge On content, data used by certain T-Mobile customer service applications, such as the T-Mobile App, and the federal telehealth VA Video Connect app, do not count against your high-speed data allotment.
If your total high-speed data usage exceeds your selected high-speed allotment during a billing cycle, we reduce your data speed to 2G speeds for most plans, kbps for the remainder of that billing cycle.

At each of our testing locations, our field researcher loaded a KB static Web page and viewed a 1-minute video while connected to each of the 3G and 4G services of the carriers.
For each one, the researcher logged the time the Web page took to load, as well as the time necessary to stream the video. You can see a lot of variance in the performance scores from location to location within our testing cities. The same service may deliver radically different results in two locations in the same part of town.
Or two different wireless services might produce very different connection speeds and call quality at the same location. In this video we drove around San Francisco to demonstrate how some of these conditions can affect your wireless coverage.
