Data speed FAQs

    Find answers to commonly asked questions about data speed reductions.




    How does it work?

    Some T-Mobile data features have a 'threshold' on the amount of data you can use at full speed during a billing cycle. After you pass the threshold, you still have unlimited access to data, but the speed of data is reduced.


    Data Speed Reduction is implemented to ensure you have a positive web experience and to help you avoid overage charges while allowing you to stay within the costs of your current plan. Even with data speed reduction, you can have a good experience with many data services, such as email, general Web browsing, and Facebook usage.


    Example scenario: You have the 'Unlimited 2 GB Data Feature' that provides 2 GB of full speed access on the T-Mobile network. You use the data feature to download videos, pictures, emails, and for Web browsing at full speed. Once you use 2 GB of data from the device, your data speed becomes reduced for the remainder of the bill cycle, but you still have unlimited access to data on the T-Mobile network.



    Do certain plans have differences in data speed reduction?

    Yes. If you have a plan that was available between November 13, 2010 and March 24, 2013, data speed is reduced to (at most) 50 kbps (comparable to dial-up) when data usage exceeds the Data Speed Reduction Threshold for data features. Mobile Internet and data-only plan customers that reach this threshold have their speed reduced to 100 kbps.


    If you have a plan that was available after March 24, 2013, data speed is reduced to (at most) 128 kbps when data usage exceeds the Data Speed Reduction Threshold for data features, Mobile Internet, and data-only plans.


    • Any T-Mobile Web feature uses data speed reduction. Mobile Web Pay Per Use (PPU) also uses data speed reduction.
      Exception: Unlimited Nationwide 4G data does not have data speed reduction or caps.
    • The data speed reduction threshold varies and depends on the plan or feature.
    • A free text message is sent when the Data Speed Reduction Threshold is reached and then data speed is reduced.
    • You must wait until the following billing cycle to return to full speed data access unless you upgrade to a higher data plan. Contact T-Mobile Customer Service to assist with this upgrade to ensure speed reduction is removed. You can also change your plan or services on My T-Mobile.


    Example scenario: Let's say your speed is reduced when you reach 5 GB of usage. You contact Customer Service to upgrade to a 10 GB plan or Unlimited Nationwide 4G data. Now, your speed is no longer reduced and you have an additional 5 GB or Unlimited to use for the billing cycle.



    Can I reset the data speed threshold if I upgrade my plan?

    The data threshold does not reset to zero when upgrading to a higher plan.


    Example scenario: If you reach threshold at 2 GB, then upgrade to 10 GB, you'll have 8 GB remaining for the billing cycle for a total bill cycle usage of 10 GB.
