It looks like T-Mobile is pushing forward with its un-carrier initiative with a new family package that offers unlimited everything for a base cost of $100 for two lines. Each additional line will run you $40 extra per line. Overall, at $180 for 4 lines, the package deal would end up saving you $40 per month over building the plan yourself, which would set you back $220 per month.
