Huawei B315s Using Mobile data when air playing _Help!

I have a Huawei B315s-22 modem with a Skymobile SIM card. Wirelessly linked I have an LG Smart TV and and iPad. I have found that if I airplay movies from the hard drive of the iPad it uses data from the SIM card account. For example yesterday I air-played two movies from the iPad and afterwards found that 8GB of data had gone?

I thought airplay (screen mirroring) would simply use the wireless network not connecting with the Skymobile network? Is this wrong? Is there a setting I can change to stop the data usage?

Thanks Peter

You need the video source on your apple phone then it will use TCP over the wifi network, if its on the hard drive for some reason airplay will transport it over the internet and back again to your tv.

Yes, It happened sometime. I have the same issues. Any solutoins?

Are the movies ones you have bought from the apple store??

Apple assumes all WiFi is unlimited, as do most American companies. The fact your home WiFi is provided by mobile data is not something Apple has planned for.

To save the battery on your iPhone or iPad, the Apple TV app on the LG is playing the movie directly from the internet, instead of from the iPad. This way you can take the iPad and use it to do something else once the movie has started.

Check in the LG settings, but you need to find an option similar to:
"Play from iTunes in the Cloud"
and turn it to OFF.

Unfortunately this setting does not appear in the AppleTV app on my Amazon FireTV stick, so it may not exist on your LG. (It does seem to appear on expensive AppleTV boxes).

It's a March OP. Suspicious newbie wakeup of the thread.
