Has anyone else had this problem? I've only had my phone for a little over two weeks (just purchased, never before activated iPhone XR). Four different times I have been out, and have been unable to text, use Siri, or anything that depends on a network connection. It shows that I have three or four bars LTE, but I get nothing. If I reset the network settings, I get everything back. Easy enough to do, but it's a pain in the a**, because it erases all of my saved Wi-Fi passwords. Talked to technical support, and they had me do a whole bunch of things (reset network settings, take the Sim card out, put it back in, turn the phone off, turn it back on). But only time will tell if they work or not. Just wondering if anybody else has been running into the same thing.
