T-Mobile is feeling good about the results of yesterday’s OpenSignal report, and so it’s kicking off some deals to celebrate.

Starting today, T-Mobile is offering its “best-ever pricing for families” on its Unlimited LTE and 10GB plans. On top of that, T-Mo is restarting its fourth line free promo, meaning that you can get four lines of Unlimited LTE for $150 per month. And if you need even more lines, you can add up to 12 for $30 apiece.

Meanwhile, the price for four 10GB lines is $120 per month. If you don’t need four lines, you can get a pair of lines with 10GB each for $100 per month.

These prices are available in stores, online, and through T-Mobile telesales, which you can reach by calling 1-877-413-5903. Both new and existing Simple Choice customers are eligible for these prices. If you do end up enrolling, you can keep your Unlimited LTE plan for a minimum of two years, and any other plan for as long as you’re a T-Mobile customer.
