It’s a good time to be a family of four. T-Mobile has just announced the latest in a series of promotions that’ll get you and three others unlimited data for just $150. Heralding this offer as the “best-ever pricing for families,” the price is pretty sweet for boundless LTE for your smartphones. And better still, families and small businesses alike can add up to eight additional lines for $30 each. So if you’re constantly finding yourself on the losing end of your data plan, it may be time to consider a switch.

If unlimited data seems like too much data, you could also consider getting four lines of 10 GB per line (remember, T-Mobile doesn’t share, so every one of those 10 GBs are yours), for $120 per month. This translates to just $30 a month, which certainly sounds like a deal. And if you don’t have a large family, you can opt for two lines of 10 GB each for $100. Sure, at $50 per line, it’s a bit steeper, so you might as well grab a couple friends and make an ad-hoc family.

“Over the past year alone, we’ve more than doubled the reach of our LTE coverage, so more people than ever can now ride America’s fastest 4G LTE network,” said John Legere, president and CEO of T-Mobile in a statement. “Last year, I told you we’d massively expand our LTE coverage, and we did. I promised we’d compete nearly everywhere with Verizon’s LTE network, and win. And that’s exactly what real-time, crowd-sourced studies are now confirming.”

The Un-carrier, which claims to be “America’s fastest 4G LTE network,” boasts that a record number of customers have been switching over for both the low prices and the additional benefits of being part of the T-Mobile family. And while one of their most frequently touted new programs, Binge-On, has received some negative attention in recent weeks, with prices like these, T-Mobile seems confident in its ability to attract new business.
