Why did I lose cellular connectivity when I downloaded iOS 11 on my iPad?

Carrier settings need to be updated?

Connect to wifi and update.

Same thing happened to me

I updated to iOS 11 today. Right after the update, I noticed I was not seeing the AT&T call letters by the signal bars. I kept seeing the following repeated sequence every minute or so:

Signal Bars with "LTE"

Just Signal Bars

No Service

When it would sequence to just signal bars or no service, I had no internet

I checked my AT&T account and there are no issues, it knows I have the card inserted in the iPad Pro.

I checked for a carrier update and there wasn't one available (did this on WiFi)

I looked in settings, the iPad knows I have an AT&T Sim Card inserted, but the Carrier tab keeps disappearing during the sequence of events above and then reappears.

I tried resetting network settings, pulling the Sim Card - Shut down and reinsert, and restoring the iPad to new. None of the efforts above resolved the issue.

I inserted the Sim Card into my iPad Mini and it worked fine. Reinserted the Sim Card back into the iPad Pro and still having the same problem. I never had this issue until after the first boot up to iOS 11.

I have an appointment at the Apple Store tomorrow to hopefully resolve the issue.

rgm 1947, do you also have AT&T?  If you and Lightwave50 have the same carrier, maybe that will help narrow down the problem.

My iPad doesn’t have cellular so I can’t test mine.

My iPhone does have cellular, with Verizon, and it’s working fine after the iOS 11 upgrade.
