T-Mobile lets you roll over your unused prepaid data

T-Mobile's Data Stash is helpful if you want to save unused bandwidth on a regular plan, but wouldn't it make more sense if you're on prepaid service, where every gigabyte is precious? Apparently, the carrier agrees: as of March 22nd, it'll let you use Data Stash with prepaid Simple Choice phone plans. Like before, you'll start out with a 10GB reserve of full-speed mobile internet access. Once that runs out, you'll bank any leftover data for up to a year. While this probably won't be big enough to get you to switch carriers (not when AT&T and others are improving their no-contract data options), you'll at least have a better reason to choose Magenta's network if you're still on the fence.
