I have a rooted EVO 4g. I downloaded the stock voice mail application, but it is not working. I get a text message that says [//ANDROID:*@vvm.coremobility.com has send you a sprint voice message. Call 4-8-970-0000 to listen.] I have the stock sprint visual voicemail, but I can not get it to work. I have emailed the vvm email that some fourms suggest, but my voicemail will just not send the message. Is there anything I can do?
