T-Mobile Announces Uncarrier 8.0: Data Stash

The big feature being introduced with Uncarrier 8.0 is called Data Stash. As you know, when you pay for a certain amount of data from your cellular carrier, that data bucket is only good for your monthly billing cycle. If you have 3GB remaining at the end of your cycle, that data is lost when your next cycle begins. Data Stash allows users to keep their high speed data that they have unused at the end of the month, which allows them to have a greater amount of high speed data for future months.

So “rollover” accounting has come to data finally. Did it really take us almost 15 years to get here?
