I had Cricket for about 8 years with no phone issues. The problem that made me switch had to do with their automatic billing. Each month they automatically debited my VISA, until they didn't. On two different occasions, they did not do the autopay, and then because it was not paid, they cut off my phone service. I have my phone mostly for emergencies, so I can't have them just cutting me off willy-nilly. I switched to Mint and have not had any issues.
