I have an iPhone 6s on the Three network.
In the Mobile Data Options (Settings > Mobile Data > Mobile Data Options) I have "Enable 4G" set to "Voice and Data".
When I make a call, my phone switches to 3G, then back to 4G when I end the call. Not a problem...just interested to know why it doesn't stay on 4G?
