All the ios device I've used display 3g, 4g or LTE in the status bar when the device is not on wifi.
How old are your clients ? 10...They probably don't need to be on the internet in the first place.
Thank you for your post.
I have tested and confirmed that if you are connecting remotely with an external address and you are disconnected from WiFi while Data is enabled it will attempt to reconnect.
Other than setting an idle time there is no good way, as far as FileMaker is concerned, to determine whether a client is connected using WiFi or Data.
I recommend entering this suggestion into the Feature Requests Web Form.
I hope this information is of use!
Thank you so much for checking that. It occurred to me after I posted that perhaps the v13 function, Get(NetworkType) could be my friend here as some kind of trigger. Perhaps the feature request is that if, on reconnecting, there's a shift from wifi etc to the data plan provider, that the user gets the option to continue or not. I'll submit this later in the day (unless others come up with better ideas in the interim!)
