-It won't let me write a new text message.

=When I get a text, it doesn't show
=When I try to check my inbox, it says, "No messages"

-It deleted all of my contacts, and won't let me add new ones.

=When I try to add contacts it just says, "cannot add more contacts".

-It deleted my recent calls, and won't let me check any missed calls.


=When I try to check my missed calls it says, "Call lists empty".

Can I fix it?
