1. I'm often with my friend, this has no Wi-Fi and only a laptop. I would like to complete a Netflix subscription and download the app to my mobile phone. Is it possible then that we watch the movies on his laptop? By connecting the phone to the laptop anyway (eg USB)?
2. Should he get Wi-Fi sometime, there's also a Netflix subscription a stick or similar that I can then stick the stick with him in the laptop to Netflix to look?
To 1: You can open a hotspot with your phone, with which his laptop can connect, then you can log in with the Netflix laptop with your account.
To 2: If he has Wi-Fi, you can log on to Netflix on his laptop as normal. The subscription is linked to your account, not to your phone. You can watch Netflix everywhere if you log in with your account.
