The word of the day for Boost Mobile is "unlimited." The no-contract pre-paid wireless carrier just rolled out three “Monthly Unlimited Select” plans with prices starting at $40 a month.

Aimed at the value-conscious consumer, all three plans include unlimited talk, text and data Relevant Products/Services. The key difference is the thresholds and speeds.

Dow Draper, president of Sprint Prepaid Group (the company that powers Boost Mobile) is hoping the new plans will even out the playing field with competitively priced offers. He said, “This new package reflects what we hear our customers want: straightforward, value-oriented options that provide more or less data depending on their individual needs.”

A Tiered Approach

Let’s drill deeper into the pricing plans. For $40 a month, you can get any Boost phone, including the Samsung Galaxy S5 starting on May 19, with unlimited talk and text and unlimited data. The $40 plan offers 500MB of high speed data. The speed slows after you hit the limit.

By contrast, the $50 a month plan offers unlimited talk and text with 2.5 GB of high speed data. Finally, the $60 plan offers unlimited talk and text with 5GB of high speed data.

Boost also offers value-added features like the Boost Mobile Wallet, a mobile Relevant Products/Services payment solution powered by Wipit. Boost Mobile Wallet lets you make payments and manage cash without carrying money or credit cards. Boost Mobile is also offering International Minute Packs that let you only buy what you need for international calling.

Why Customers Like Boost

We caught up with Jeff Kagan, an independent technology analyst, to get his take on Boost Mobile’s new unlimited plans. He told us pre-paid customers appreciate the Sprint-owned company, in part, because pre-paid plans often cost less than traditional post-paid products.

“Boost provides pre-paid talk, text and data -- and now at a lower cost,” Kagan said. “Every customer Relevant Products/Services has their own unique usage and needs. Boost just introduced three new Monthly Unlimited Select plans so their customers can choose the best plan for themselves.”

Kagan compared and contrasted the Unlimited Select Plans this way: each offers unlimited connectivity so you can always be online, but the difference in price between the three plans dictate how fast your connection runs at certain thresholds.

“When you run out of high speed data capacity Relevant Products/Services your speed slows for the rest of the month. That's why it's important to choose the best plan for your needs,” Kagan said. “Pre-paid is a rapidly growing sector of the wireless industry and Boost is an important player in that space.”

Indeed, Boost Mobile is gaining momentum in the pre-paid marketplace. J.D. Power recently recognized it as having the “highest satisfaction with the purchase experience among non-contract wireless providers.” The phones run on Sprint’s 4G LTE network Relevant Products/Services. Boost Mobile offers devices from BlackBerry, HTC, Kyocera, LG, Motorola, and Samsung.
