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?
