How to Turn Off Yahoo! SMS Alerts

1. Log in to your Yahoo! mail account by entering your username and password at mail.yahoo.com.
2. Click your name in the upper left corner next to the Yahoo! Mail logo. A drop-down menu appears beneath your name.
3. Select 'Accounts' from the drop-down menu. A new tab opens with your account dashboard.
4. Scroll down to the 'Notifications and Subscriptions' section and click the 'Set up Yahoo! Alerts' link.
5. Click the 'My Alerts' tab across the top under the Yahoo! Alerts logo.
6. Turn off only SMS alerts for an individual subscription, but keep the alerts on your other services such as email, Yahoo! Messenger and the Yahoo! iPhone apps, by clicking the 'Edit' graphic next to the alert you want to change. Then, uncheck the box next to the 'Mobile' field and click the orange 'Save Alert' button in the lower right corner.
7. Turn off all Yahoo! alerts for an individual subscription by clicking the green 'On' button next to the alert name, located under the 'Status' column. This turns off not just your SMS alerts for the subscription, but also any alerts to your email, iPhone app and Messenger account, if you have set them up.
8. Turn off all Yahoo! alerts for all your subscriptions, including all SMS alerts, by clicking the 'Off' link next to the 'Turn All Alerts' section, located in the 'My Alerts' tab under your list of subscription alerts.
