Issue:
On devices with iOS 13 and up, users might notice that by toggling airplane mode in settings on/off, there is a popup message displayed that says, "No SIM Card Available". This is part of the IOS functionality that versions of IOS 12 and below do not have. Unfortunately, Sauce Labs does not have control over this functionality.
Resolution:
If you need to enable+disable airplane mode on a device with IOS 13 and up, you should be able to do this by clicking "OK". After disabling airplane mode, the device automatically reconnects the device to wifi.
