[On3 AI](https://kb.on3.ai/on3-ai?hsLang=en) # Add your phone number to receive workspace SMS notifications ## For first-time and returning users: open your On3 profile, add a mobile phone number, and check your contact details for workspace SMS notifications. Add a mobile phone number to your On3 profile so your workspace administrator can send you SMS notifications. You can do this after your first sign-in or at any later time. This guide shows the On3 web app. The account menu screenshot uses a test account; your name, initials, workspace, and role may look different. ### Before you begin - Sign in to the On3 account associated with your workspace. - Have the mobile phone number where you want to receive your workspace's text messages ready. - Use a number you can access, and keep it up to date if your number changes. ### 1. Sign in to On3 #### If this is your first time signing in Open the On3 login link provided by your organization and complete the sign-in instructions. Once you are inside your workspace, open your profile using the steps below. You can add your number after signing in; you do not need to wait for a later visit. If you need help accessing your account, see [How to log in to On3 and reset your password on mobile and web](https://kb.on3.ai/how-to-log-in-to-on3-and-reset-your-password-on-mobile-and-web?hsLang=en). #### If you have signed in before Sign in as usual. If you are already signed in, continue directly to your profile. The same profile steps apply whether you are adding a number for the first time or checking an existing number. ### 2. Open your profile 1. Find your account menu in the upper-right corner of the web app. It shows your profile image or initials. 2. Open the menu and check that it shows the account and workspace you expect. 3. Select **Profile**. ![On3 account menu showing Profile above Help center and Log out](https://kb.on3.ai/hs-fs/hubfs/Screenshot%202026-11-10%20at%207.13.50%20PM.png?width=470&height=313&name=Screenshot%202026-11-10%20at%207.13.50%20PM.png) *Select Profile from your account menu. The name and workspace shown here are examples.* ### 3. Find the Phone section On the **Profile** page, go to **Contact Details**. Look for the row labeled **Phone**. If no number is stored, the row displays **No phone number added** and an **Add Phone Number** button. ![Phone row in On3 Contact Details showing No phone number added and the Add Phone Number button](https://kb.on3.ai/hs-fs/hubfs/on3-profile-add-phone-number.jpg?width=640&height=75&name=on3-profile-add-phone-number.jpg) *Use Add Phone Number in Contact Details to begin adding your mobile number.* **Use the correct section:** **Profile Details** contains your first and last name and a **Save Profile** button. Phone numbers are managed separately in **Contact Details**. ### 4. Add your mobile phone number 1. Select **Add Phone Number**. 2. Enter the mobile number where you want to receive SMS notifications. Follow the number format requested on the screen and check the country code if one is shown. 3. Review the number carefully for missing or incorrect digits. 4. Follow the on-screen instructions to finish adding the number. Complete any additional steps the app requests before leaving the flow. 5. Return to **Profile → Contact Details → Phone** and check that your number is displayed correctly instead of **No phone number added**. If a number is already displayed, check whether it is current before making a change. Use the phone controls shown on your profile if it needs updating. ### 5. Receive notifications from your workspace administrator Keeping your mobile number on your profile gives your workspace administrator a number to use for SMS notifications. Adding a number does not mean a workspace message will arrive immediately. Messages depend on what your administrator sends. If you are expecting an SMS, ask your workspace administrator to confirm that the notification was sent to you. You can also return to your profile at any time to check that your contact number is correct. ### Troubleshooting #### I cannot find Add Phone Number Make sure you opened **Profile** from your own account menu and are looking in **Contact Details**, not only in **Profile Details**. If a phone number is already listed, review the controls beside that number. If the section is missing or you cannot make a change, contact your workspace administrator. #### My phone number did not appear after I entered it Review the phone setup screen for an error or an unfinished step. Follow any instructions shown, then reopen your profile and check the Phone row. Do not assume the number was added until you can see it on your profile. #### I added my number but have not received an expected SMS - Check that the number on your profile is correct and belongs to the phone you are using. - Confirm that your phone can receive text messages and check for blocked or filtered messages. - Ask your workspace administrator whether a notification was sent to your account. #### My mobile number has changed Return to **Profile → Contact Details → Phone** and use the available phone controls to update it. Finish the on-screen steps and confirm that the new number appears on your profile. ### Need help? Contact your workspace administrator or On3 support at [support@on3.ai](mailto:support@on3.ai).
