iPad Pro: Losing (AT&T) LTE Connection. Possibly iOS9.3-Related

I've been noticing, over the past week or so, quite a lot of cases where my iPad Pro loses its (AT&T) connection. It goes to "No Service."

Switching Airplane Mode on and off doesn't seem to help, nor does switching Cellular Data off then back on doesn't seem to help. So far, only rebooting it seems to clear the problem.

No, I haven't tried a hard (both-buttons) reboot yet. What the heck, I'll probably try that next...

I'm not sure if it's related to iOS9.3, but it seems to be roughly in that time frame...

Anybody else seeing anything like that?

iPad Pro, 128GB-OTHER, iOS 9.3.1

Try a Force Restart. Press and hold both the Sleep/Wake and Home buttons for at least ten seconds, until you see the Apple logo.

If that doesn't help, tap Settings > General > Reset > Reset Network Settings

You will have to enter your Wi-Fi password.

Yeah, as I mentioned, I hadn't tried that yet (it only occurred to me as I was posting). I just now did so. I'll see over the course of the next couple days whether it seems to help, and report back.

So far, a couple days afterward, the hard (i.e., both-button) reboot seems likely to have solved the problem.

It took ~3 days, but even after the hard reset, it did lose the LTE connection again today. I'll try resetting network settings (probably this evening).

After doing "Reset Network Settings" a few times, I'm finding that it's still losing LTE from time to time. Not clear that any of those resets, nor the both-button hard resets, have had any substantial effect. Hmmm...

You might also want to make contact with AT&T and see about the possibility of a bad tower in your area, or you could also see about a replacement SIM card.

That's a good thought, thanks, but the dropouts don't seem to geography-related. I lose the connection when I'm at work or when I'm at home, which are on opposite sides of Austin. Also, when the iPad drops out, I have not seen any reduction in the "number of bars" of reception on my iPhone.

The only thing that seems to help, albeit temporarily, is hard (two-button) resets and resetting netwo settings.

That's an interesting suggestion; I'll look into it. Thanks.

Hmm... I'm not sure how I, apparently, marked this as solving the problem, but apparently I did somehow do so. No signs that it's geography-related...
