There will be no Active Device limit for any tier.
- What do pushes include?
Pushes include all notifications delivered to the platform notification services (e.g. Windows Notification Service, Apple Push Notification Service, Google Cloud Messaging, and Microsoft Push Notification Service).
- What is an Active Device?
Active Devices are devices eligible to receive notifications and are defined as unique registration IDs for devices using Google Cloud Messaging or Amazon Device Messaging, channel URI (Uniform Resource Identifier) for devices using Windows Notification Service or Microsoft Push Notification Service, or device token for devices using Apple Push Notification service. Note that a physical device can count as multiple Active Devices for Notification Hubs.

Broadcast refers to the number of devices that you can send a Push Notification to with a given notification request. Tags are keywords that devices are subscribed to. A Broadcast Push Notification can be sent to all devices that are subscribed to a particular tag.
Notification Hubs in Free and Basic tier, when broadcasting to an audience, will push to at most 10,000 devices. If more devices are present in the targeted audience, 10,000 devices will be chosen at random and the remaining ones will not receive any notification.

A Namespace is a grouping mechanism and may contain multiple Notification Hubs.
