Do I need an XBox subscription for the XBox to connect to the internet?

Hi, I hope you're doing great out there. I am an Independent advisor and I am here to help you in regard to your concern.

Not at all. An Xbox Live Gold subscription is only required if you will be playing an online multiplayer game for paid games.

1. Is your console connected to Xbox Live? (you just need to connect it to the internet to do that.)

2. Do you have an Xbox Live Gold subscription?

Hello, to play on Xbox you will need an internet connection and a subscription to Xbox Live in order to play only with others.

On the Xbox One, you do not need an Xbox Live Gold subscription to use the Cloud. You just need to be connected to the internet. Any profile connected to the internet will use the Cloud service.

More information here. There is no confirmed number of max profiles on one console.

Fallout 76 will use the same internet connection as any other Xbox One online multiplayer game and the same internet connection that your console has. You will need an active Xbox Live Gold subscription too. So you simply need to make sure your console
is connected to the internet and Xbox Live, and then launch the game, and you'll be good to go.
