Had switched to an LG K20 V phone about, say, a year ago. Everything worked fine, no problems.
At some point during the holidays (say like two weeks or so now), my mobile data decided to stop working. Can't text message, can't e-mail, can't go online, can't use the Google GPS, can't do anything unless I'm connected to a Wifi. As soon as I turn off Wifi or leave to take a drive, nothing will work. At the corner of my screen there's 3G with active bars next to it, and yet my mobile data isn't working.
Tried all the basics: turn off phone and turn it back on, turn off phone and take the SIM card out and then put it back in and turn it on, turn on and off airplane mode, and finally I gave in and did a factory reset. Nothing has been working and I'm getting pretty annoyed at this point.
The only thing that I think may, perhaps, be an issue is that the SIM has 4G on it and yet it says connected to 3G on the top. Don't know if that means anything but a quick glance around leads me to believe that it shouldn't really matter. Could be wrong.
Just looking for some kind of advice at this point.
