Sprint prepaid brand Boost Mobile announced a limited time offer that will reduce prices and double data for its Monthly Unlimited Select plans.

From Sept. 3 to Nov. 3, customers will be able to get $40, $50 and $60 plans for $5 less. All the plans will still include unlimited talk and text but now $35 gets 1GB, $45 gets 5GB, and $55 gets 10GB.

The plans are available to new and existing customers.

Sprint’s move on the prepaid side of its business follows closely on the heels of its recently unveiled $60 unlimited everything single-line plan. That plan requires customers to sign up for Easy Pay device installments or to bring their own device.
