All this is to say: Sprint's offering to cut your bill in half if you switch to its network from Verizon, AT&T, or T-Mobile, while still providing you with a comparable data and calling plan. You'll have to make the switch between Nov. 20, 2015 and Jan. 7, 2016, but those commercials where people hack paper with chainsaws and machetes are coming to fruition. For example, if you were paying, say, $80 a month for T-Mobile's 10GB plan, Sprint's new offer would cut that down to $40 a month for 10GB. Additionally, the offer will pay the cost of breaking your contract, up to $650, if you ditch your old phone and sign up for two years of service on Sprint.
Of course, there are caveats. Exempt from the plan is T-Mobile's unlimited data plan that runs $95 per month. And the offer doesn't apply to pre-existing Sprint customers. And, take into consideration, you'll have to use Sprint's network, which, as of the last Consumer Reports ranking of major carriers, ranked dead last, scoring "dismal marks." But this is Sprint's attempt to take back market share by luring new customers with literal cut-rate plans.
