T-Mobile just expanded its $99.99 per month, all-you-can-talk-and-text plan by adding in a family component, according to Engadget Mobile. It works like this: Buy the first line for $99.99 as you normally would. Then, add up to four additional lines of service, each with the same "limitless bucket of minutes and messages," for $49.99 for each additional line.

The company is packaging it on their site as "FamilyTime Unlimited," which includes two lines configured as such for $149.98 per month. But "make no mistake, you can still add another three on top of that to make sure all the kiddies get their fair share," the report said.
