Even after numerous factory resets, through both the Volume Down+Send+End and Settings>Privacy>Factory Reset methods, my Eris has been unable to send or receive texts, and will not allow me to send or receive calls. When I try to text, I get an SMS error with Cause Code: 34 and Error Class: 3. When I try to call, I get an automated error saying that my phone can't be authenticated at this time, and am advised to call #8899. Even after doing so, I get the same authentication error. Wi-Fi seems to work correctly, and my Google and Facebook accounts all sync pretty much perfectly. Is anyone else having any kind of problem like this? And, either way, does anyone know of any possible alternatives that may fix the problem besides a total replacement of the phone?
