Boost Mobile, the no-contract carrier that's owned by Sprint, is offering a new promotion for T-Mobile, AT&T and Verizon customers. Boost Mobile says it can offer savings of up to 50% for those customers if they switch over to the carrier.

Boost Mobile adds:

For a limited time, customers who ditch T-Mobile, AT&T or Verizon for Boost Mobile family plans will get 10GB of high-speed data per line. Plans start at two lines for only $60 a month. In addition to offering high-speed, data-packed family plans, Boost Mobile also will provide a free phone or $50 instant device discount for every line a customer brings over from T-Mobile, AT&T and Verizon. Available for a limited time in participating Boost retail stores, new customers can get up to four free smartphones when activating a family plan.

The promotion that offers the 10GB high-speed data per line will run until April 5.
