I am in a suburb 44 miles west of chicago and my coverage has always been from good to great with no problems whatsoever. I have an iphone 6S that was a new insurance replacement from about 6 months ago. Not sure if this is relevant but about a month ago I took a cross country drive to Palo Alto, CA and back. My coverage was spotty wheere I expected it to be but it never came back the way it was before and after the IOS 12 update it got even worse. My voice calls do not consistently go through and frequently drop after a few minutes and I can't reconnect, even when I'm stationary with 4 bars. The cellular data does not work at all. If it says LTE and I try to use it, the LTE disappears and comes back with a 1x. I usually see 1x but it does not recognize the data network at all. I'm a long time Virgin mobile user, I currently have 2 lines. One works fine but my problem phone makes me want to throw them both out the window.
