Network Connection Error

If you want to (or must) use the Exposure Notification system on iOS in Japan, you must use this app. If you attempt to register in the app before you arrive, you will get an unhelpful “Network Connection Error”.

The app will not let you proceed unless you are connected via a Japanese network. Note that international roaming on a foreign cellular network will not work. You must connect via a WiFi network in Japan or via a Japanese cellular network.

Network connection error issue resolved

A lot of people in reviews comments they have network connection error after accepting terms of use. The Japanese Ministry of health website said you cannot use it if you are not in Japan. I assume you will be able to use it once you landed in Japan.
I hope this helps many of you having this issue.

Needs verification

Thank you for providing the app.

A major limitation is the lack of any feedback that the app is functioning properly and recording close contacts. It is like having a smoke detection without a test button.

I believe showing a count of recent contacts over a period of time does not raise any privacy concerns while at the same time adding a bit of confirmation.
