Khai is the best. When I returned from vacation and my phone stopped holding a charge, he spent nearly two hours with me trying a few different methods to charge my battery with an external charger, transfer all of my files and select a new phone that best suited my needs, along with some accessories. Lesson learned, I'll actually back up my stuff from now on.
Cricket overall has been great to me, I don't have any service or coverage issues and I pay less than my friends for comparable plans. Their Android selection is somewhat limited but you can purchase phones through Best Buy, Walmart, etc and activate with your Cricket Sim card.
