My iPad Pro was doing great up until about two weeks ago. I noticed one day that it had lost its cellular connection. I thought hmm, maybe it's just a weak signal. Didn't think much of it, but after two days, I tried rebooting it and it returned. A few days later it rebooted during the night. And lost the signal again. I rebooted it again in the morning and the signal came back. The other day, another nighttime reboot and lost signal. Did the same thing. This morning, while no nighttime reboot, the signal is gone again. It's not that I use the cellular signal; it's the point of it. How many other folks are having similar problems?
