[kris05]

How would someone getva verification code if they don't have their mobile service working at the time due to billing issues

Where are you trying to get the verification code from?
Is send by email an option?

[realaud]

Choose another verification method, such as email.

Usually on the things that send these, there is an option for "I cant use my device right now" or something to that effect.  If you never provided any other method to whomever or whatever is trying to send it, then you may have troubles, otherwise, it should be able to e-mail you like Realaud stated.
