Lately, in good coverage area (4G), my 9900 keeps dropping to "SOS"...any chance this could be a bad SIM?
I just completed a complete wipe and loaded up .576 (ATT's latest official) because my phone wouldn't allow me to open texts. This being a week since I awoke to a slow blinking red light with alternating slow blinking trackpad light, to which a battery pull resolved.
I should also note, after the wipe and update, my SIM shows "Unknown Number" however the SOS issue started before the wipe but after the brick-like issue.
mine keeps doing the same (UK Vodafone) sim changed and still the same issue, so they are dropping off a new phone to me at work today, never had this issue with my black 9900 but this white one has been nothing but a pain!
OS update should help in this, update to the the latest one, independent of the carrier, you could also try putting your phone in manual mode rather than the automatic
I had this issue even on my Bold 9700. Telus told me it was a network issue came after they upgraded their system to support H+ system. They told me even though 9700 can't support H+, this network upgrade had issues in Calgary area for some customers.
During the first month owning my Bold 9900 I ran in to SOS, but then it went away. I haven't seen SOS ever since. So, I assume this is a network issue and Telus may have fixed it.

if u have the latest 7.1 os official or leaked version on your 9900 and it keeps giving u that message , its prob a sim issue. you can goto your carrier and theyll provide u with a new one, that should take care of things for u
