Had no signal so I ....
Had this weird problem in a remote area where I've always had decent service. No signal at all. Zero. Its in ski country where I go every week. So I went for two days like this, drive home and I got a signal again when I was a few miles from the dead area.
So I come here again next week and it happens again. I start looking at the settings. The voice roaming is set to " on". I turn it off for a minute and back on. Then BAM! I have 4 bars. It's been fine all morning. I tried this last week and it didn't work. Very weird. Anyone experience something like this?
