On an old phone or whatever. I outright refuse to give facebook my cellphone number for account verification. It annoys me that giant companies like google and facebook are doing this. Rip the free and open internet. 

If you can help pm me your number. I had an old cdma lying around but gave it to the salvation army.

edit , if you know a work around let me know too i tried using 'recieve sms online' but facebook says the number i used was recently used to verify a different account.

All i want to do is make a facebook account and what should take 10 minutes annoys me for half a day
