Easy question and just making sure they are 100% correct.
A visitor who will be here awhile has an Apple notebook and Apple phone.
They say wi-fi is only for their laptop and they use wi-fi for music and no internet with their phone. They are implying that their Apple phone can not access the internet. We do not believe them.
They use their laptop to transfer music to their phone and then use the phone to listen to music outside the home. The problem is they are using internet to all hours of the night. They think they can stop using the laptop at a certain hour per "rules" and only use their phone. Talking loudly on a laptop or phone is the same thing to us.
