Register devices in cloud app

[Tokatubs]

Is there a way to register a device(android or ios) to the cloud app, without using the wifi modell described in for example the video for push notifications.
I have no problem connecting the device to the cloud app mosaic. But i dont get a string for the phone model, so i guess i cant register for push notifications. 

Now i have a problem with a client where there is problem with connecting wifi router, so i cant register the phone via wifi.
