    Just since installing beta 4 of iOS 8, I am now getting random "No SIM Installed" pop ups forcing me to quickly restart to recover, or if I delay, I am required to reauthorize the phone. It happened 4 times yesterday and three times so far today (and the day is early). One time while I was driving, listening to a podcast via bluetooth and also using Waze at the same time, it happened in an AT&T deadzone. I thought perhaps it might be related to weak or no signals, but then it happened again in my office with a good signal. I can't identify what triggers it, but I have a valid SIM installed, and I am using an AT&T account on an iPhone 5 of recent manufacture.
    I was going to report it with the Bug Reporter, but it is no longer available in iOS 8 beta 4.
    Is anyone else experiencing similar problems?

    I haven't seen this issues in b4 so far. Try taking out your SIM card and cleaning it off. It may not be making good contact.

    Thanks for the suggestion. I did just that yesterday and thought it might be coincidence and not related to the beta 4 release.

    Since it happened a few times today again, however, I don't think that was the solution.

    Oh, by the way, it gave me a slightly different message today.
