A method of notifying a mobile station regarding data usage with a plan limit includes tracking an amount of data usage consumed by the mobile station. A first data usage limit and a first data usage time frame are determined from a user account. A comparison is made of the data usage to the first data usage limit and a present time to the first data usage time frame. From this comparison, a projected data usage amount is determined and whether the projected data usage exceeds the first data usage limit. If exceeded, the system analyzes a second data usage limit to determine if it is greater than the projected data usage amount. If greater, the server provides a message to the mobile station notifying the user of the projected overage and suggestions to change to a new plan offering the second data usage limit.
