Understanding the IoT Device Provisioning Service registration limitations

When reading the limitations of the DPS: https://learn.microsoft.com/en-us/azure/iot-dps/about-iot-dps

Then it say 1 million registrations and 50 IoT Hubs, so my question is:

The limit on devices in an IoT hub is 1 million devices, but when I have one DPS with multiple IoTHubs then I am still limited to "only" 1 million devices? I will not be able to use the sum of all the possible registrations that the backend IoTHubs can handle?

    Hello @Mikkel Vagtborg Welcome to Microsoft Q&A Platform and thanks for your query.

    I agree that each IoTHub has 1 Million devices limit. But the DPS quotas are per Device Provisioning Service instance. Below is the response/confirmation from the product team.

    Quotas are per DPS. The number of enrollments/registrations can be increased by contacting Microsoft Support.

    Please comment below to let us know how can we help you further in this matter.
