Yorktown301, that's very strange, but I'm here to figure this out! Are you still having problems connecting to 3G or 4G? Let's first verify that no settings on the phone were changed. Go to Settings, More, Mobile networks, Network Mode. Ensure LTE/CDMA is selected. Go back to Settings, Data usage and make sure Mobile Data is on. If still no change, remove both your battery and SIM card for about 30 seconds. If you're still having problems, let me know what zip code you're located in.
