Using mobile data while wifi are reserved

You might be best advised to seek assistance directly from from Apple Support. You can contact the Support Team using the Get Support link at top-right of this page.

Alternatively, you can initiate and manage your support cases using the excellent Apple Support App. If not already installed on your iPad, the App can be downloaded from the App Store:

Hey Janne,

If you haven't already, check your cellular data settings are enabled for the app: View or change cellular data settings on iPad (Wi-Fi + Cellular models) - Apple Support

If that doesn't help, we recommend reaching out to Furuno Support: Furuno Support

Thanks for participating in Apple Support Communities.

Take care!

While your iPad has both a Cellular and WiFi network interface, the iPad can only route traffic via a single interface. In technical terms, your iPad network connection is not dual-home - and cannot simultaneously use to network connections.

If your radar does not employ a cellular connections of its own - and has the capability to act as a Network Router, your iPad will not be able to route traffic to the internet while associated with the closed WiFi network provided by your radar.

Does your radar have a bluetooth connection? If so - and you can pair the iPad with the radar via Bluetooth - you will be able to access the internet via your iPad’s Cellular connection.
