You need to pay to play online on Switch, Xbox and Playstation,

There is no way around this

Hi, my name is , I'm an Independent Consultant and a member of the Xbox community like you. I'm sorry for the problem you're having.

If you are having problems with Minecraft on switch, I recommend that you contact Minecraft support, they can help better with problems related to the game;

My
friend and I want to connect with Xbox. I use a mobile phone, he uses a computer, all bedrock version. But he ca n’t enter the archive I opened, but I can go in the archive he opened, and I want to ask how to solve it.

Hey 尚卿吴,

This issue is most likely a Mojang issue and you can contact them
here. This could also be because you and your friend are on different versions of Minecraft. You can check the mobile version on the app/play store in the app description. On the Windows 10 version you can change what version of Minecraft you're on. From
the Launcher window, select "Edit Profile" and open the version drop-down selection.

Hope this helps.

Did you get a code or buy it from Microsoft? If you have a code you will have to go to the store and apply the code.

Hello,

You are required to be sure the version purchased was for PC , My next step in advice will be to contact xbox directly by phone for further assistance.
