I read this page that explains T-Mobile's policies on data use:
I commend the company for such an open and straightforward description of these policies.
One thing was unclear: how some of the policies apply to family plans.
The document refers to "customer" in many places. Does "customer" mean a family plan as a whole, or a single line within the plan?
Specifically, the section "Network Management for Extremely High Data Usage" explains that "customers who use more than 25GB of data during a billing cycle will be de-prioritized for the remainder of the billing cycle in times and at locations where there are competing customer demands for network resources."
On a family plan with unlimited data, is the 25GB threshold and de-prioritizing applied to the entire family plan? That is, does the de-prioritizing kick in on all lines in the plan if the total data for all lines hits 25GB?
Or this it a per-line limit, where each line has its own 25GB threshold and only the lines that exceed that get de-prioritized?
Or does it work some other way for a family plan?
