For the past couple of weeks the sms errors keep coming back and my phone doesn't ring but I get voicemail notifications. No missed calls for it either. Also can't dial out sometimes and get signal fade or call lost error as well as network is busy please try again later. Has there been outages in North Los Angeles County the past few weeks? It's getting frustrating. What's worse is that it comes and goes. Some days it's fine and some days it's terrible. My neighbor has boost and he has been having similar issues. I know both Virgin and Boost use Sprint towers. My phone (Evo V 4G) got the over the air update back in January.
