Frequently asked questions

  • T-Mobile provides Broadband Labels for plans that we currently offer to new consumer and small business customers with data access to all, or substantially all, of the internet. The labels contain information like price, fees, and data speeds to help you make an informed decision on what wireless services best fit your needs. You can find these labels where you shop for your plans, including on our plans page, on the phone, or at a retail store.

  • As discussed in the Network Management section, we offer a range of rate plan and brand choices with different network priorities. Where the network is lightly loaded, customers will notice little, if any, effect from selecting a plan with lower network priority. This will be the case in the vast majority of times and locations. At times and locations where the network is heavily loaded in relation to available capacity, however, those customers will likely see reductions in data speeds, especially if they are engaged in data-intensive activities. Depending on the extent of network congestion, these customers may notice more frequent impacts to real-time services like video conference calling, 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 at constrained locations, the frequency of heavy loading in relation to available capacity may be greater than at other locations. When network loading goes down or those customers move to a location that is less heavily loaded in relation to available capacity, those customers' speeds will likely improve.

  • No. We don’t prioritize traffic on the basis of who created the application subject to the same reasonable network management practices as other data on the network.

  • We use a variety of physical, electronic, and procedural safeguards to protect our network from events that may negatively impact our customers' ability to use our broadband internet access services. We monitor our network to protect against security threats, including spam, viruses, automated attacks, worms, distributed denial of service attacks, and other potentially malicious activity. When we detect a threat, we may attempt to prevent it from spreading across our network using a variety of security measures, which may include, among other things, requiring device software updates and rerouting, prohibiting, or limiting some traffic over our network, typically until the threat is resolved.

    Unless part of a customer-chosen service, T-Mobile does not block lawful traffic based on content or subject. Occasionally, cases arise where T-Mobile must make a judgment, determining that the value of protecting our customer base from malicious or other adverse, network-impacting traffic outweighs access issues experienced by a few. Examples include Internet sources or destinations that are major sources of spam and sources that aggressively scan Internet addresses or those that have attempted attacks against T-Mobile infrastructure or customer end-points.

    T-Mobile blocks a limited number of Internet addresses that are disruptive or malicious and typically persistent, based on our review of third party industry-wide intelligence.

    For our Wi-Fi services, which are accessible in a wide range of commercial establishments and public venues, T-Mobile prevents the use of certain ports that are commonly used to spread malware and engage in other malicious activity.

  • T-Mobile customers may use any compatible GSM, 4G LTE, or 5G device, such as a tablet or smartphone, to access our Broadband Internet Access Services, as long as they do not cause harm to our network. T-Mobile may limit activations of compatible devices on older technologies as we transition our network to newer technologies.

    If you did not purchase your device from T-Mobile, please be aware that T-Mobile has not made any determination as to the call quality, performance, or other functionality provided by the device.

    Our customers may use our broadband internet access services to access any lawful application, including real-time applications, in a manner consistent with our Terms and Conditions. T-Mobile reserves the right to take whatever measures are necessary to protect our network from potentially harmful devices and applications. The performance of a real-time application on our network depends on the speed and latency of the subscriber's connection, as well as their chosen data plan (see above for details).
