I did not receive a confirmation message because my phone wasn't text enabled. I have since contacted my mobile phone provider to enable it. Do I need another confirmation message sent?

No. If your SMS phone was already submitted to our database, you should be confirmed to receive SMS alerts from us. However, you may also test to find out by texting the word "SUBSCRIBE CSUSB" to 23177 and you will receive a reply with the following:CSUSB Alert: This phone number has already been opted in. More info text reply "HELP" or "STOP CSUSB" to opt-out.
