I use Skype to make some international calls. This works well if I am at home/office and connected to Wi-Fi.

However if I am on move, I prefer to turn off Wi-Fi to prevent connection to public Wi-Fi networks so that it won't affect my ongoing calls.

Sometimes after calls I forget to turn on Wi-Fi and start using some other app which can consume substantial amount of data.

Is there is any way to disconnect Wi-Fi for just a few minutes (the estimated duration of the call)? Or to force app calling features to use cellular only?

  • What exactly do you mean by "prevent connection to public Wi-Fi"? What public networks is it connecting to?

  • It would help to know if these are just "random starbucks" or carrier-specific public access points. One is pref-controlled, the other is profile-controlled.

  • @Tetsujin These are some random starbucks kind of public access points. Nov 28, 2019 at 4:19

Rather than manually managing when you are connected to untrusted WiFi access points, you should consider setting up a VPN connection that is automatically enabled when you connect to WiFi. That will protect your data - even when on a public WiFi network. At that point, you don't need to worry as much about whether WiFi is on or off.

  • Thanks for the answer. Will having a VPN prevent IOS from automatically connecting to wifi. I have a VPN setup on my phone . Also I have set Settings->wifi->Ask to join networks to Notify. It still connects to public network like starbucks etc. Nov 28, 2019 at 4:23
  • I think you may have to tell it to forget structures it has previously connected to, then the pref should work.
