T-Mobile is no stranger to introducing discounted service deals to lure in new customers. Its latest enticement is a two-person family plan, which offers unlimited 4G LTE data for two lines, in addition to unlimited call time and texting for $100.

“People are saying loud and clear that they hate the confusion and complexity of the carriers’ shared data plans, and they should,” John Legere, president and CEO of T-Mobile, said in a statement.

“These plans are purpose-built to do one thing -- take money from your pocket and put it into theirs. They threaten you with punishing overage penalties unless you police your own family’s data usage or up your data bucket and spend more every month.”

T-Mobile’s two-person family plan undercuts family plans on other carriers by at least $60, the Verge notes.

Customers will be able to sign up for the two-person family plan offer starting Wednesday. While the offer will be available for a limited time only, there's no limit on the plan itself. Subscribers will be able to use the plan even after the offer has expired.

The two-person unlimited data plan is available for new and existing T-Mobile customers. Additional lines can be added for $40 each and all lines must have 4G LTE data.

Customers should keep in mind that the $100 pricing is only for the service. They will have to purchase their devices either through T-Mobile’s equipment payment plan, or pay full price.

T-Mobile has also reinstated its four-line family plan, which offers 10GB of 4G LTE data or 2.5GB per line, for $100. T-Mobile introduced the plan in July, after other carriers, Sprint in particular, introduced family plans with cheaper rates.

The four-line family plan will be valid throughout 2015, after which subscribers will be downgraded to 1GB of data per line.
