I am currently using an LG Optimus L9. I get 4g coverage in my area, but for some reason this afternoon my coverage disappeared. I had blue bars, just no 4g. I restarted my phone, and disconnected the data a few times and it hasn't come back. Now whenever I try to connect to t-mobile gsm network, it says it's unavailable and connects me to AT&T, which still isn't 2g, 3g, or 4g. I have seen other posts where people have asked if they are working on towers, but how would I find out if my area is being affected? Should I call t-mobile on this?
Thanks in advance for any advice =)
