Two low-cost providers, RadioShack No Contract and Spot Mobile, have decided to call it quits. RadioShack didn't operate a traditional MVNO, but branded and resold Cricket Wireless' service as its own. Now that Cricket is owned by AT&T, and RadioShack No Contract struggled to win over customers, the company will cease selling the service. According to RadioShack, customers who purchased the service will be able to continue using their device and will be transitioned to Cricket Wireless. RadioShack will honor its 30-day return policy so those who recently purchased a RadioShack No Contract device can get a refund. RadioShack's retail business is also hurting and the company plans to close a wide number of stores this year. Separately, Spot Mobile, an MVNO that resold access to T-Mobile's network, also decided to shut down. Spot Mobile has already ceased processing account refills, and will shut down service altogether September 7. Spot Mobile said customers can port their number out to their carrier of choice.
