"No SIM card" Android Error (Verizon Galaxy Note 2)

[Hunter-AP]

[del]So my SIM card is usually perfectly fine, and every once and a while (about 4-5 months), it isn't detected by my phone. It happened again yesterday, except restarting my phone did not fix the problem, unlike any time before this. Now no matter what do, the SIM card is not detected.

When I tried to find out on my own, all the answers claimed it MUST be something wrong with the SIM card reader, but I doubt it because it happens so rarely.
I tried restoring all my apps/app data with my Titanium Backup files, but to no avail.

Is this a technical/software issue that I can fix myself, should I order a new SIM card, or am I supposed to get Verizon/Samsung to fix ti for me?[/del]

So get this: My SIM card was the wrong way. I honestly have no idea how my phone worked with the SIM card being backwards, but now it works perfectly fine. I can't believe how ridiculous this was.
