How to restrict WiFi from certain Apps (in order to save data on expensive airplane data packages)?

It is really necessary to make sure there is no unwanted data being exchanged through WiFi, as each bit costs a lot of money above the clouds (starlink might change this in future).

Thank you, adil727!

Dear Giulio,

Thank you for your help. Could you please show me how I could (as an example) restrict the App 'AppStore' from using WiFi using 'Screentime'?

Unfortunately, I could not find any explanation on how to achieve this in the link you provided. Also I was unable to achieve it by playing around with settings within 'Screentime'.

Thank you

If it is guaranteed that there is NO data connection whatsoever for unopened apps when background refresh is disabled, then your solution would be a workaround to deal with the problem/situation (not really the solution, as it would be better, if the user could simply control the device as needed).

In the airplanes where I was offered a data connection though WiFi, I only had a choice of data packages such as 10MB, 100MB and 1GB. Obviously at horrendous prices.

Thank you, SravanKrA

Dear Giulio,

The question was solely about WiFi and not about Cellular connection (there is no cellular connection in airplanes usually).
