My LG G3 has no service, can someone help me?

[AC Question]

For some reason my phone doesn't have any service. I tried restarting my phone and pull my sim out and put back in however i have 0 bars. I know there isn't any problems with my sim and my family has no problem with their coverage. I would really like some advice on how to resolve this issue. Thank you.

If you've tried toggling Airplane Mode and Mobile Data and similar tricks, the device may be faulty. Before returning it for replacement or repair, you might as well try a Factory Reset, since you'll have to do that anyway.
