Data drains last 2 days

[ewankim1023]

My 10GB Mobile data has been drained last 2 days including Boost packs.

The funny thing is that I was watching videos with my phone while I was connecting home Wifi and I got a message from 150 that I used all my data.

I purchased another subscription pack that I need to urgently use but still it's not renewed as I have call allowance left?

Apple & Android phones have a data counter facility, which gives a breakdown of usage app-by-app.

The two OS do differ slightly in their other options, but Apple sometimes has an option for using mobile data when WiFi is weak.
