T-Mobile has revamped its family plan, as part of its "Uncarrier Amped" announcements. The new scheme has two people each having unlimited calls, texts, and 10GB of LTE data for each line for $100 per month, with additional lines including their own 10GB allocations costing an extra $20 per month, and an additional 10GB of data available at $10 per month per line. From now until Labor Day, the carrier will cut the cost of the fourth line entirely, making the four-person family plan with 10GB of data each cost $120 per month.
