"SMS Error Cause Code 97 Class 2."
 
 Explanation:  This is an error when attempting to send SMS messages.  Usually the problem is with the texting 
plan.. or lack of a texting plan on your account..  When signing up, if they ask you to call in to an automated number 
to activate your plan.. please do it..  I've heard that people didn't call into the automated activation line and 
months later, SMS's stopped working and they started getting this error.. Then they needed to call the cellular 
providers tech support...
 
 Also.. if you have root'd or unlocked or played with your smartphone enough (and therefore can't/don't get updates form 
your cellular provider), I've seen the provider make chances.. push out new software which with a root'd/unlocked phone 
you won't get.. and then SMS's stop working..
