Hi, i just got a new HTC Vivid last night. I had originally gotten the HTC Vivid on the 4th of this month and that one kept randomly turning off 2-3 times a day so i got a brand new one last night in Amarillo, TX. When i got home to Borger, TX last night i wasn't able to send text messages and now today my phone is saying that i can only make emergency phone calls due to my mobile network being turned off. When i go to my notification bar into quick settings and try to turn mobile network back on it wont even let me select turning it on. What is going on???
