i recently got a new dinc (within the last week) and it worked fine for a while but then suddenly stopped being able to call or text. i get the cause code: 1 and error class: 3 when i try sending a text, and when i start a call i hear an automated voice telling me that my the authentication for my phone has failed. i've tried reprogramming it a few times using *288 option 1, which fixes the problem for a few hours, but then it stops working again. does anyone know a fix or why this happens?
