Find answers to commonly asked questions about domestic data roaming.
When did this change take effect?
April 5, 2012. Changes to Mobile Broadband took effect on September 25, 2013. See the Mobile Broadband Q&A below for details.
Why did T-Mobile make this change to my account?
To continue providing the most competitive pricing options in the industry, T-Mobile has chosen to introduce a domestic data roaming allotment on all data plans. At the time of implementation, based upon usage patterns over the last year, we anticipate that fewer than 1% of customers will be impacted by this change. Domestic roaming allotments are used across the wireless industry and so this is common with other carriers as well.
Did this change affect all lines on my account individually or did my account have one limit?
Each line of service on your account will have a separate domestic roaming allotment based on the data rate plan for that specific line.
How much data can I use each month while roaming domestically?
This depends on your data plan. The larger the data plan, the more domestic data roaming you have access to each month. This also means that if you exceed the amount for your plan, you may be able to upgrade to a larger plan either temporarily or permanently. Use the chart below to determine the domestic data roaming allotment for your data plan.
Current Rate Plan Full Speed Data Allotment
New Domestic Off Network (Roaming) Data Limit
1MB to 199MB
200MB to 1.99GB
2GB to 4.99GB
5GB to 9.99GB
10GB to 12.5GB
Unlimited Nationwide 4G Data
|Limited 2.5GB to 4.5GB Data SMHS||50MB|
|Mobile Web Pay Per Use||10MB|
Note: The megabyte allotment for your data plan can often be found by reviewing the Available Service Section on page one of your bill (ex: Classic Simple 200MB Data Promo) or by dialing #WEB# from your mobile phone.
Will I be charged for domestic data roaming?
No, T-Mobile does not charge for domestic data roaming. However, once your domestic data roaming allotment has been reached your data services will be unavailable until you return to a T-Mobile coverage area, your bill cycle starts over or you increase your data plan. If you have a Wi-Fi capable device, you may use Wi-Fi to access unlimited data.
How will domestic data roaming appear on my bill?
It will not appear on your bill as there are no additional charges associated with domestic data roaming.
How will I know that I am near my domestic data roaming allotment?
You will receive a free usage alert via text message to notify you once you use 80% of your monthly domestic data roaming allotment. You will receive another free usage alert via text message to notify you when you reach 100% of your domestic data roaming allotment. These text messages will contain a link that will allow you to view your real-time usage. You can also view your domestic data usage by using the MyAccount feature on your device once you have exceeded 80% of the monthly allotment (whether you are roaming or not).
How can I manage my data usage?
There are several things you can do to better control data usage:
- Use Wi-Fi whenever possible, especially when downloading apps or music and when streaming music or video.
- Set email and other social networking applications that synchronize data to “manual” mode instead of “automatic” so you can control when you are synching data.
- Android phones can use applications like My Data Manager to track and control usage. It is not a T-Mobile application but may be very useful.
How can get access to data again after I have exhausted my domestic data usage allotment?
You can upgrade your data plan to one that includes a higher domestic data roaming allotment (temporarily or permanently), return to the T-Mobile network, wait for your billing cycle to start over, or use Wi-Fi for unlimited data access if you have a Wi-Fi capable device once you reach your domestic data roaming limit.
Can I still access data using Wi-Fi?
Yes, many devices are Wi-Fi capable. If you have a Wi-Fi- capable device, you can always access a personal or public Wi-Fi network, allowing you to use data independently from the T-Mobile or a domestic roaming network. This is also a great way to avoid domestic data roaming and we recommend that you use Wi-Fi when you are in a data roaming area whenever possible.
I live in a domestic data roaming area and my device often reads something other than T-Mobile on the screen. How will I be impacted?
Your standard voice and messaging services will not be impacted by this change and data usage will operate normally until you reach your domestic data roaming allotment. Only after you reach your domestic data roaming allotment will data services be impacted. Even after you reach your domestic roaming data allotment you will continue to be able to use your device to make calls and send text messages.
How do I get my device to stop roaming when I've gone back into a T-Mobile coverage area?
If you have re-entered a T-Mobile coverage area and your device does not indicate that T-Mobile is the carrier you can turn your device off and turn it back on.
Will the domestic roaming allotment impact my ability to send Multimedia Messaging Services like picture messages, video messages, etc.?
No, even if you reach your domestic data roaming allotment you will still be able to send and receive Multimedia Messaging Services.
Does my domestic data allotment change based on the device I use?
No, the domestic data allotment depends on your data plan and is not device specific.
How does the domestic data roaming allotment impact my Mobile Broadband service?
On September 25, 2013, all postpaid Simple Choice data features and Mobile Broadband (MBB) plans will have the same domestic roaming data experience. Previous to this change, MBB had a different experience.
If you have a MBB plan, you can use data while domestically roaming up to the limit of your data allotment. Then data is shut off while roaming. Once you are back into your home area, you can then continue to use data (which is at the reduced speed based on your plan allotment).
Does this change impact my Rate Plan, Terms and Conditions of Service or my contract term with T-Mobile?
Yes, this notice amends your Rate Plan to include the specific data roaming allotment associated with your plan and revisions have also been made to the Terms and Conditions of Service. Please consult the Terms and Conditions for more information.
Will all data services be blocked if I reach or exceed my domestic data roaming allotment?
Yes, most data services will be blocked when you reach your domestic data roaming allotment, however, you can still access the My Account features on your device.
