Cheesy moniker aside, Sprint's newly minted Framily plan is not one to be ignored. It allows you to save money by sharing an account with, well, friends and family, all while being billed separately on up to 10 lines. Following in similar footsteps, AT&T's prepaid subsidiary Aio Wireless has now announced Group Save, which allows users to get a maximum monthly discount of $90 per account. It's simple, really: the more lines you add, the more cash you save every month on your bill total, not per line. With Aio's Group Save, you can have up to five lines; the first two get you a $10 discount, while lines number three, four and five knock off $30, $60 and $90 per month, respectively.
