Is anyone else having signal issues today? I have not been able to recieve or send txts or calls all day. It seemed to begin this am at work. I was getting a 4G signal at NAS Corpus Christi. Then after that, signal would alternate from 3G with signal, to roaming and eventually circle with line through it. Still like that now at home. Just throwing it out there to see if anyone else is experiencing issues. Could be 4G related. Sorry if this is not the correct venue to ask.
