Have you added your phone as a push device or SMS text contact in your user page? In your Alarm.com account, head to users and you can customize your contact addresses.
Then, under the Notifications tab, you can select the desired recipients of an Arming/Disarming notification you create.
See the images below.
Have you done this and are still not receiving the notifications?
