Heads up: With Mobile Share Plus, we may temporarily slow your speed when the network is busy.

About data use and overage charges

Say goodbye to overage charges. Instead, we’ll just slow your speed to 128Kbps (2G speeds) for all lines on your account if you use all your data in a bill period.3 Your speed goes back to normal when your next bill period starts.

Reduced data speeds

If we slow your data speed, you can still view websites and check email. But, some activities may not work fully at slower speeds, including:

  • Audio and video streaming
  • Picture and video messaging
  • Interactive gaming
  • Downloading and uploading large files

Advanced data usage notifications and options

All phones on an account get a text and email when 75% and 100% of the data allowance is used. This will give you an opportunity to avoid reduced speeds by adjusting your data use.

If you use 100% of your data allowance and want faster speeds, you’ve got options:

  • Use Wi-Fi® instead of mobile data until the next bill period. Your plan data resets when the next bill period starts, and your data speed will return to normal.
  • Switch to a plan with more data before the end of the bill period. You’ll get a new data allowance with normal speeds after you switch.
    • Want to switch your plan? Go to your wireless account overview. Select Change my plan under your plan name.
    • We’ll backdate your plan to the beginning of your bill period as long as it doesn't have an account or service change. This will make sure that you get charged for that plan for the month. 
  • Get tips on how to manage data use. Examples include temporarily turning off data for specific devices, or using Wi-Fi to reduce mobile data use.
