I've had this issue since I got my iPhone 7 when they first came out and it has nothing to do with Airplane mode. Apple kept saying it was a Verizon issue, and Verizon kept saying they didn't know or to call Apple. They'd tell me to erase my phone, etc, which did nothing. So frustrating. Sporadically it would work, but again, nothing to do with Airplane mode. So many times when I was traveling and really needed internet or Google maps and got nada. NOW Apple cops to it being their fault.
I just called a local Apple Store and the person I spoke with hadn't heard of the issue (as per usual), and said they'd have to run tests and would only do something if they found a problem. Hopefully it won't be the rare time my phone is working. And while I don't get dropped calls, I do get bad connections all the time, even with 4 or 5 bars.
