MetroPCS today kicked off a limited time family plan deal.

Starting today, you can get four lines of unlimited talk, text, and LTE data for $100 per month from MetroPCS. New and existing customers are eligible for this deal, but you will need to add at least one new line of service to qualify.

There are some details about this plan to keep in mind. While unlimited LTE data is included, video streams will top out at 480p, and customers that use more than 35GB of data in a month will have their usage deprioritized. Additionally, there is no tethering included with this plan.

MetroPCS will also give you a free smartphone (you pay sales tax) for each line that you port in. The phones that are available with this offer are:

• Alcatel Fierce 4
• Alcatel Fierce A30
• Coolpad Defiant
• LG Aristo
• LG K20 Plus
• Motorola Moto e4
• Samsung Galaxy J3 Prime
• Samsung Galaxy J7 Prime
• ZTE Blade Z Max
• ZTE Avid TRIO
