Can two different facebooks be linked to one mobile number?

My sister doesn't have a phone but uses mine a lot. Since I text my status updates to my fb, she wants to do the same with my phone when we're out. And since I text the number assigned to me from fb, I assume she would be given a different number to send her statuses to?

You can try it but i'm 90% sure that they wont allow it because the phone number is usually used by Facebook to verify who a user is.
