"SOS" Notation in Signal Strength Indicator
My Verizon signal has been flaky tonight, often showing no signal at all. I hope it's the carrier and not the BlackBerry. (WiFI works fine.) Connection status for phone = "Unavailable." Yes, I did a battery pull.
At some point I noticed a red "SOS" in place of the normal signal bars. It was there only for a few seconds and then disappeared.
What is that?? Signal available for 911 only, perhaps? Mystified hereā¦

it also happens when you current network goes down however you may be roaming on another network for emergency calls only. if you had zero signal, not even enough for a 911 call, it will just say searching for network indefinitely.
most likely a network issue or a tower went down in your area. - 03-20-2011, 08:51 AMThread Author #4
Thanks for the replies. It's ok this morning. I was pretty sure it was a carrier or tower issue, I'd just never seen "SOS"on the screen. Signal read 3G so I knew it hadn't switched to GSM; signal level was -156 dBM (I think when there's no signal it goes to -256 dBm, right?).
The "roaming on another network for 911 calls" concept makes sense, I think.
