How do I cancel all mobile alerts?
Because many phone companies recycle phone numbers, it is possible for users who purchase a new phone to receive a previous owner's alerts. Since your phone has an email address that anyone can send a message to, Yahoo! can only stop alerts that it manages. Only your carrier can prevent all messages from being delivered to your device. If you would like to cancel all alerts, navigate to the My Mobile page. This page features a main device and beneath that lists other mobile devices. Click the link Cancel All Mobile Alerts.
