New Horizon Experience. This article describes the New Horizon Experience. In the Horizon WebRef mobile apps for Android and iOS, New Horizon is already what you see. On a computer or laptop, choose Try the New Horizon Experience from the banner or your account menu. You can switch back from that menu any time.
This article covers assignment text messages on Personal Profile under Notifications. Officials and other signed-in members set this for their own account.
Use it when you want assignment texts, when you want to stop them, or when a carrier warning appears. For the rest of the profile, see Personal Profile. Quiet hours are also on that same Notifications card. See How do I change the time text messages are sent?.
Both layouts are in use right now. In the Horizon WebRef mobile apps you see the New Horizon Experience. On a computer or laptop, the older legacy layout stays until you choose Try the New Horizon Experience from the banner or your account menu. Match the steps to the screen in front of you.
Opt in or opt out
Sign in, then open Personal Profile and choose Notifications.
On a computer, the same screen uses the wider layout.
Assignment texts are off until you choose a Mobile carrier that matches your phone service. Leave Mobile carrier blank to opt out. You can also set a maximum number of texts per day (including unlimited when offered) and quiet hours with Do not text before and Do not text after.
Save the Notifications section if the page still shows unsaved changes. Send test text sends a sample assignment-style message to your mobile number after your profile and mobile details are saved.
When a carrier no longer delivers free texts
If Mobile carrier is Verizon, AT&T, or T-Mobile (or already saved as one of those), a warning appears titled This carrier no longer delivers free assignment texts. Those carriers have discontinued their free Email-to-SMS gateways, so assignment texts through that setting will not arrive.
Install the Horizon WebRef mobile app for Android or iOS to get push notifications instead. On New Horizon, View Premium SMS opens Add-on services when that option is shown. Devices enrolled for push notifications are listed on the same Notifications page.
If your carrier is not listed, use the in-product help link for unsupported carriers.
If you still see the older legacy desktop or laptop layout
On the older all-in-one profile, these fields sit on a Text Messaging tab instead of a Notifications tile. Mobile carrier blank still means opted out. The same Verizon, AT&T, and T-Mobile warning can appear there without a View Premium SMS button. The Notifications tile belongs to the New Horizon Experience.
