How many texts is outbox on a voyager suppose to hold?

My inbox is holding more than my outbox and it automatically deletes the messages in my outbox when I have Auto Delete turned off. What could be the cause of this?|||The voyager can usually hold around 200 messages (inbox) and 100 messages (outbox). It can be more or less depending on the space you have on your phone. If your phone is filled with music and pictures and videos, it will probably not be able to hold as much.
