Using mobile data
The app can download over mobile data. How to turn it off and what happens when you do.
Efatah downloads little at a time, so mobile data is on by default.
To turn it off
In Settings › Downloads, in the network section, turn off mobile data. Larger downloads then wait for wi-fi.
What keeps working
Even with mobile data off, the app still fetches the essentials of the current section (text and images) so you are never stuck. Audio waits for wi-fi; meanwhile the device voice speaks instead.
The Downloads screen also shows how much internet the app used this month.
