It's always wise to check for Recto-cranial Inversion Syndrome.

Since SMS is used as a third or sometimes fourth authentication step, I
don't think that it lends itself to being usefully cracked. Someone
would have to know the username, password, and cell number of the target
account (sometimes the PIN also), and that's simply unlikely except in
the case of specific high-value targets. Those accounts already employ
additional levels of security (banks don't expose million-dollar
accounts to basic online access).
