What happens to Messages sent to Iphone if I haven't paid my bill?

I have an Iphone. I forgot to pay my bill. I have a friend who tried to message me, but I couldn t receive them because they aren t Imessages. Will I receive the messages he sent me when I pay my bill?

If within a certain space of time, yes you should

If they were sent when you didn't have service you won't get them when it's turned back on.
