There is no limit to the number of Alerts you can sign up for. You can sign up for multiple types of Alerts as well as sign up multiple times for each type of Alert.
For example, you can set up a low balance Alert to be notified at home anytime your checking account balance drops below $200.00. You can then sign up for another low balance Alert and have it alert using your cellular phone anytime your account balance drops below $50.00.
