Sprint has announced the introduction of new family plans, aiming particularly for T-Mobile and its plans. The Sprint Family Share Pack offers four lines with unlimited talk and text, with 10GB of shared high-speed data for $100 per month.
The carrier is also offering to quadruple Family Share Pack data for $20 more per month. This would give you unlimited talk and text, and 40GB of shared high-speed data for $120 per month.
For a limited time, Sprint will also help select customers pay off their current phone and wireless contract on rival carriers in order to get them to switch. Customers will need to use their American Express Reward Card after registering with Sprint online, and Sprint will only pay after you've turned in your current phone.
