When you exceed the number of subscribers in your current plan we will trigger daily email alerts letting know that you are ready to move on to the next Beams tier. You’ll have 7 days from when you first exceed your plan to upgrade and avoid any problems with sending Beams notifications.
If you fail to upgrade before you reach your plan limits you will receive a '402 (payment required)' response code returned for any attempted publishes and notifications will not be delivered to your devices.
