Does Netflix cost anything if I already have an account?

I wanted to download Netflix to my cell phone but I don't know exactly whether I have to pay anything, because I already have an account on the TV.

You can also log in to your mobile phone account from the TV

You can access the same account on all devices, just like with Spotify.

The Netflix basic subscription for 7.99 euro: you can stream films and series from Netflix on one device in standard definition (SD). You can also use this subscription to download titles to a smartphone or tablet.

The Netflix standard subscription for 11.99 euro: allows you to stream films and series from Netflix on two devices at the same time in HD (if available). With this subscription you can also download titles on two smartphones or tablets.

The Netflix Premium subscription for 15.99 euro: allows you to stream films and series from Netflix on four devices at the same time in HD and Ultra HD (if available). With this subscription you can also download titles on four smartphones or tablets.

Expert? Well What does that mean here?

More than those who give their mustard to something who have no idea about it

But your answer is unfortunately not correct. Look mine

Well then tell me why you can't log in to another device with your existing account?

OK. Give me your telephone number. There's no audio option here.

And you missed a very substantial part of your own answer.

The crux of the matter is "at the same time".

The additional costs are only for watching something on Netflix on more than one device at the same time. Not how many devices you are logged on to.

Of course the answer is correct. With the Netflix Premium subscription, you can register on up to four devices at the same time. It doesn't matter whether it's a computer, smartphone, television or console.
