Yesterday a leaked document suggested that T-Mobile was prepping “an unbeatable rate plan offer” to replace its 2 lines for $80 promo plan, and now that new rate plan is official.

Starting tomorrow, May 11, T-Mobile will offer a family plan with 4 lines of unlimited talk, text, and data as well as 6GB of high-speed data per line. Pricing for the rate plan is $30 per line, or $120 per month, and you can add additional lines at a price of $20 each.

T-Mo says that its new family plan offer will be available for a limited time. It’ll be offered in stores and through telesales.

In addition to this promotional rate plan, T-Mobile is kicking off a deal that’ll get you a free Samsung Galaxy Grand Prime with the purchase of a Galaxy S7 or Galaxy S7 edge. With this deal, you’ll get a $190 prepaid MasterCard card to cover the cost of the Galaxy Grand Prime. This deal requires at least one new line, and you must also buy the GS7 or GS7 edge on an EIP.
