iOS Question Is it possible to detect roaming?

[nwhitfield]

In one of my B4A apps, which allows users to display profiles and photos of other users, I detect a) roaming and b) wifi connections.

So, by default, if the device is roaming, it won't load photo automatically, but only when requested - unless on WiFi. And users can also choose to have higher resolution photos delivered, when using a WiFi network.

This is generally aimed at making sure that people don't unexpectedly end up with large data bills.

Is there a way on the iPhone to detect if the device is roaming?

It is not possible to detect the roaming state. You can check ServerSocket.GetMyWifiIp to know whether you are connected to a network (note that it is still possible that the internet network will be routed through the cellular network).

I guess that's why you hear more horror stories about iPhone users with big bills after holidays ;-) I know friends with iPhones that have had shocks, and I've had to show them where to turn off the confusingly named 'wifi assist'

I could, I suppose, use GeoLocation, and if it doesn't match the country the user has on their own account details, decide that way.
