It's related to the network issues. I haven't seen that message today (or last night), but I continually saw it last week when the network was down. I wouldn't worry about it unless it continues after the network is back up for everyone and you still can't connect.
I had it too. Turned off my phone, turned it back on (never touched the SIM card) and it works fine. But the network in my area of Michigan is off and on today.
I guess I spoke too soon in my earlier post. I just received the error, but a restart appears to have fixed the issue. What was also strange is that I was on a call, and when it ended my screen would not come back on. I had to reset (Power + Volume Down) and that's when I received the error. This is the first hiccup I have had with my Razr. I'm hoping it's all related to the network, but I'm starting to get a bit frustrated with the outages.
Hard reset (not to factory settings) No 4g (yes it is enabled), my formerly rock solid connectivity is gone, the phone keeps saying "verizon wireless over and over which is letting me know it is dropping connectivity. For the moment I don't see the sim card error.
I love technology, I am an early adopter, but at this price it may not be worth it. My old Droid Incredible never had one single issue like this for it whole life time.
I have now had the sim card "authorization error for nearly 24 hours. Only on 3g all this time. If they make me hard reset on this brand new phone for the 4th time I just may take it back. Really what is the point of having to troubleshoot your phone every few days.
