T-Mobile brings back its 4 for $120, 10GB-per-line deal

T-Mobile is bringing back one of its most popular promotions by — once again — offering four 10GB data lines for $120 total. The offer is available for a limited time from today, and is ideal for data-hungry families needing multiple lines. With no overages, you know exactly what your bill’s going to be every month too.

If you don’t need four lines, you can get two 10GB lines at $50 each:

With #10Gigs4All, two people can get up to 10 GB of 4G LTE each – no sharing required – for just $100 a month. Then, each additional line is just $20 more per person – also with 10 GB of T-Mobile’s blazing-fast 4G LTE. Now, with this promotion, that 4th line is free, bringing the total cost to just $120 per month for a family of four.

As with every Simple Choice plan, customers signing up get access to a host of awesome offers including rollover data for up to 12 months, Wi-Fi calling, unlimited music streaming and unlimited in-flight texting with GoGo. Customers also get unlimited calls to and from Mexico and Canada, as well as the ability to use 4G LTE data from their plan allowances in those countries, unlimited data and texts in 140 countries abroad and unlimited international texts from the US. Compared to the other three carrier options, it looks a fantastic deal:
