So, I just switched from the triumph to the Evo V 4g today. I'm totally in love with this phone, but shortly after I got it I began having voice calling and texting problems - I kept getting the Radio Interface Shortage SMS Error that, after searching the forum, seems to be kind of common. I called Virgin and they had me fix it by doing a profile update in the system update settings. I did that and it started working fine. Just a couple hours later, it started doing it again. I did the profile update again and it worked again. My question is, are there any other fixes to this, if it starts acting up again? It's going to be really annoying if I have to do a profile update several times a day just to be able to call someone or send a text - Not to mention the texts and calls I'll miss because I wouldn't even know it's not working until I try to send a text or make a call. Does the "Update PRL" in the system update settings have anything to do with this? Should I do this too or just continue to do the Update Profile? Hopefully it won't mess up again, if it continues to give me errors intermittently, it's gonna annoy the sh!t outta me. Any suggestions or fixes from personal experience?
