Facebook Mobile Verification

Facebook deleted my account 3 weeks ago, due to using "fake name" cause I used symbols in my name. So I created a new account tonight. But it won't let me activate the mobile. I can use it on my phone but I can't activate my number. It says "The phone number you're trying to verify was recently used to verify a different account. Please try a different number."

Can I please get some help about this?

Buy a new number and verify your account

It says so clear ,
Do as it says . You need new phone number.
