T-Mobile new promo can score you 4 lines with unlimited LTE data for $150 per month

T-Mobile already had some of the best family plans around, but the carrier's new promotion sweetens up the offer even further. For a limited time, T-Mobile is now offering four lines with unlimited LTE data at $150, or four lines with 10GB of LTE data per line at $120.

From time to time, T-Mobile brings out its offer on four lines with 10GB of LTE data for $120, meaning that we're not surprised to see this being included in the new promotion. What's interesting to note, however, is that the carrier has also introduced the option of four lines with unlimited data for $150, which is the price subscribers usually has to pay for three lines with unlimited data.

The carrier's usual services apply to the new family plans, although most of them are a bit obsolete when it comes to the unlimited plans. 20GB of rollover data for up to 12 months, free music streaming through Music Freedom, and free video streaming through Binge On are pointless on an unlimited plan, but the free voice, text, and data roaming in Canada and Mexico might come in handy for those who travel a lot.
