What happens if you don't pay your cell phone bill? If you don’t make a payment every month, your phone services will end. You might get some leniency at first, maybe a late fee or two, but at some point, they will cut your phone service off entirely. This is pretty intuitive: if you simply pay the bill by the due date, you won't have any issues. 

This concept of paying to keep your service active is so simple, that you’d think everybody understands it. However, that’s not always the case.
