T-Mobile must change its practices in the next 60 days, according to the Federal Communications Commission.

Soon the mobile carrier will have to give customers a heads up when their data speeds are altered.

According to the FCC, T-Mobile has agreed to change the way it handles customers who hit monthly data limits. Currently, when they hit their limit, T-Mobile allows them to continue using data, but at reduced speeds. 

The FCC says T-Mobile will now be more upfront with customers about those reduced speeds. 

In a statement the company added the changes will "prevent any confusion" for customers.
