The number of devices you can stream on at the same time depends on how you subscribe to BritBox Premier.
If you subscribe directly through BritBox
You can stream on up to 4 devices simultaneously. This is double the limit of the standard BritBox plan, which supports 2 concurrent streams.
You don’t need to manage your devices manually. BritBox keeps track of your devices using a rolling list, which updates automatically. When you sign in on a new device after reaching the limit, the oldest device on your list will be signed out. If that happens, you can simply sign back in on that device to refresh the list.
If you subscribe through Amazon Prime Video Channels
You can stream on up to 3 devices simultaneously with both Standard and Premier subscriptions.
For more information about concurrent streaming on Amazon Prime Video Channels, please refer to Amazon’s Customer Service pages.
