So you are saying I should toggle off the Wi-Fi and Bluetooth and additionally after that put the device on Airplane Mode ? That's what you are saying ? Right ?
Sorry to but in, but I don't think that you need to switch off the toggles and then put it in Airplane mode. Putting it in Airplane Mode should automatically turn off Bluetooth and WIFI connection. As the toggles in Control Center are not enough and people have to go to Settings to turn them off anyway, it's easier to just put the iPad in Airplane mode.
