SMS text messaging is pretty cut and dry, either its working or something is seriously wrong. I’ll go over a few issues and some simple fixes, but if the fixes don’t work you should take the Curve in for service. Remember that the BlackBerry runs on complicated software and it is fairly common for issues to arise. For any issue that arises on the BlackBerry Curve, taking out the battery and then replacing it should be your first step.
Can’t Send or Receive Messages:
Make sure that your BlackBerry has a signal, and a data connection. The letters next to the antenna (1XEV or EDGE) will be capitalized if you have data service. If the letters are lower case, you can pull the battery, wait 30 seconds, then put it back in. If this doesn’t resolve the issue, you may need to call technical support, so they can look at the issue on their end.
Messages are Erasing Themselves:
This is more a problem for the BlackBerry Pearl than the Curve, but if your BlackBerry starts to run out of memory, it will delete non-saved messages to conserve space. Go into “Options" and the “Status." If number after “File Free" is under 15 million, you probably need to delete some applications, or move things to a memory card. Running out of memory will also have other signs, like sluggish response times for applications. Before erasing anything, you may want to consider removing and replacing the battery, since it will free up some memory if you haven't done that in a long time.
An SMS Message is Cut Off in the Middle:
SMS messages can only be 160 characters long, so if a message is longer than that, the BlackBerry breaks it into pieces before it sends the message. Wait for a few minutes and the rest of the message should show up.
