I actually found two ways LOL

Way 1:

Step 1: Login into your facebook account.

Step 2: Put in some random number

Step 3: Send a text  "F" to 32665 (Facebook's number)

Step 4: You should get a text back in about a few seconds.

Step 5: Put in the code

Step 6: You should be able to log in.

If that didn't work then here is another way.

Way 2:

Step 1: Grab your phone and call 206-376-1000

Step 2: Make your account (It's free!) It will give you a little description and whatever. It will also ask you questions just put something random. Make sure you have a code that it will ask for is like 1234 or something that you can remember. Then make your voicemail. You can put your name or just a simple "hello" will do. Don't talk fast!

Step 3: It will give you a phone number. Put it in the verification box and then wait a lil bit then call your number. Put in your code thing and * and you should get your voicemail from facebook.

Hope I helped ^^ Everything I gave you was free!
