For my fellow S3 users that are using an airave. If you are receiving an error 97 message unplug your airave and let it sit for ten minutes before plugging it back in and turning it on. Once turned back on and all lights have stopped blinking you should be able to send and receive messages. This is what I had to do and it fixed my error 97 message. Hope this helps someone.
