SMS not working even though it says it processed

[kristinacree]

I am currently trying to get SMS on notifications working but running into some problems. I created a notification, added some information to the SMS Alternate field. I am in the group that should be receiving the message. I updated my notification settings, added both my cells (personal - AT&T and work - Verizon). I set up that the newly created notification would go to my email, personal, work and push notifications via my system settings - notifications - that specific notification. I created a defect, the table I have the notification on, and I receive the Email and Push notification, but neither SMS came through. I updated my settings to only go through for my cell phones and tested it again. I still never received the SMS. Is there anything else I should be looking at to narrow down why this isn't working?

Do you see the message in outbound emails? Maybe there is an error in system log that tells us something because your setup sounds correct.

Oh, and if I email myself, not through ServiceNow, it works fine.

Just to confirm, you went into notifications (clicking the gear in upper right corner) and activated the notification for the new notification device:

Yes, I added the Notification Channels (under the gear) and enabled for that specific notification for both my personal and work cell.
