Message storage
The Inbox and Outbox share a fixed amount of memory in
your SIM card. When there is no more room to store messages,
the
indicator blinks. If you are sent a text message
when the memory is full, the phone displays the message

No space: message waiting. You should delete one or more
old messages to make room for the new message. The network
will re-send the message at a later time.
Note: Depending on your SIM card, the Inbox and Outbox
can contain a total of up to 50 messages.
