Make calls and Netflix at the same time?

I would like to call WhatsApp with a buddy and then watch Netflix at the same time.

He's watching Netflix on his computer.

I actually but somehow it crashed and doesn't work anymore (Windows 7 (HP brand) or something older and on the Samsung tablet I can't log in to Netflix why it goes everywhere except there)

And we wanted to look together for a long time and talk to each other about it and so because we always used to do it.

But now I don't know if something doesn't crash there and stuff.

Because when I called jmd on Insta I couldn't watch Netflix because otherwise the sound has broken off, the call has broken off, and there was no picture on Netflix…

So generally you need a correspondingly fast line if you want to do several things in parallel.

Netflix HD needs around 16 Mbit inbound. Whatsapp phone not that much, but just keep going in and out.

If you only have a slow line this can quickly become a bottleneck.
