0 Which SID should I use when setting up SMS, and why am I not receiving SMS messages? 2 Ken Roach posted 10 Years Ago In order to set up SMS with Twilio (Admin Tools/Communication Settings/Communication Transports/Twilio), you have to enter a SID and a token. The help on the SID field is: "Your Twilio Account SID (find at https://www.twilio.com/user/account) " In Twilio, however, if you have more than one number registered, there are multiple SIDs. There is a SID for each number: And there is the account SID: Please confirm that it is, in fact, the ACCOUNT SID that should be entered in Rock? I have tried both SIDs, but neither seem to work. And that the AUTH TOKEN is the ACCOUNT AUTH TOKEN value? I have created an SMS message to myself. It is showing in the Communicaton List as approved, but I don't think the messages are being sent. Is this for the same reason that emails were not being sent? (Issue #375) I note that the number I am trying to send to is a New Zealand number, and that Twilio documentation states that international numbers must be prefixed by "+" to work. Entering a + before a number in the Person Profile page does not save/display the +, so I presume that this is already being done. I have also assumed that in order for SMS to work, the Twilio number must be a US number (and not a New Zealand number), so that the SMS is originating from within the US using a US Twilio number.
