to eliminate unwanted use. The Airrave used the customers' own bandwidth to connect calls—potentially slowing internet speeds on less ample connections, and causing the customer to essentially subsidize the Sprint network. Sprint was one of the only carriers that had not charged its customers for this type of device if the customer demonstrated that Sprint coverage was inadequate where they lived. Airave 2.0 was a device that supported up to six devices simultaneously and data usage. The device required a land-based internet service (such as DSL or cable modem) to produce the CDMA signal. The Airave 2.5 improved reliability and had two LAN ports. Airave 3.0 was a device that broadcast both CDMA and LTE using band 41 that was approved by the FCC in late 2016 and became available in 2017. It required a cable internet connection and included a WAN RJ45 port and two RJ45 ethernet LAN ports. The Magic Box created its own Band 41 LTE signal and used Band 41 or Band 25 LTE signals instead of a cable connection for the internet. It was designed to be placed on a window sill and broadcast to the inside of a building plus outside the building for 100 meters or further.

The products and services were initially available through Walmart stores; Sprint Nextel had planned to expand the distribution of Common Cents Mobile to other outlets, but never did. On May 18, 2011, Sprint Nextel discontinued operating its Common Cents Mobile pre-paid brand, on the basis, it was a duplicate of the offerings of the Virgin Mobile USA PayLo brand. Common Cents Mobile customers were transitioned to a Virgin Mobile payLo service
