My mobile data and my wifi isn't working?

[lol who cares]

Okay, so for some reason my mobile data and wifi isn't working on my LG G2 phone. It was working perfectly fine last night. I done some research and so far, nothing is working. I tried restarting it, putting it on airplane mode, taking out my sim card...It's super frustrating. I heard that creating an APN could help but I don't know how. I clicked on APN and the only thinking showing up on the screen says NO APNS? Is it because I'm on the wrong network mode? What network mode should I be on? Please help, I'm not at all tech savy or whatever and I just don't know what to do anymore. OH, also on my lock screen it says service disabled...What do I do?

Bring it to your carrier. There are a number of problems with the phone, at least one of which only they can fix.
