Cricket is a MVNO that uses Sprint's network. As such, priority for calls and texts are given to Sprint customers on Sprint's network. If there is a situation with high demand on the network priority will be given to Sprint customers. In those instances, Cricket customers may not be able to call out or if they are in a call, that call may be dropped to allow the Sprint call to complete. We should be thankful in my opinion that companies like Cricket exist to provide cell service for those with bad credit or people who don't want to or can't spend a lot on cell service. I travel a lot so for me Verizon is where it's at.
