Frequently Asked Questions (FAQ)<

By conducting IOT, you can verify your product’s connection compatibility with KDDI’s network and prevent network connectivity problems before your product goes on sale. You can also advertise your product as officially verified in connecting to KDDI’s network.

KDDI does not guarantee a product’s quality just by passing IOT. For manufacturers, please use your own quality certification for your products.

To conduct IOT, your product needs to be equipped with a chipset or a communication module that has passed IOT. For requirements regarding the network, please access the Member’s site. Depending on the availability of equipment and facility, you may not be able to conduct IOT on your desired time.

The criterion is to pass all test items defined by KDDI based on the specifications of the product. The test outline is available in Member’s site.

IOT includes network protocol-related tests. Performance-related tests are not included.

There are two types: "KDDI Network IOT" for verifying connectivity with the KDDI Network, and "au Starlink Direct IOT" for verifying connectivity with au Starlink Direct.

"KDDI Network IOT" and "au Starlink Direct IOT" are independent, so "KDDI Network IOT" testing is not a requirement for "au Starlink Direct IOT" testing.

If you are using one of au models that supports the eSIM transfer feature, or an Android smartphone that has completed this IOT setup, you can issue an eSIM directly from your device’s settings screen.

No. eSIM transfer is offered as an optional service for "KDDI Network IOT" and is not mandatory.

Yes. The service is supported on 5G smartphones running Android 16 or later.
