Minecraft server on mobile join not possible?

I bought a server from G-Portal for a month but I'm too stupid to join it on my cell phone. I set to version 1.16.1 as in the AppStore. IP and port from the server information but do not get it. What am I doing wrong?

You probably have an old version.

Have you ever tried to buy a new cell phone and then tried it on?

The server above seems to be for the Java edition. But you use Bedrock. You need to use Bedrock server software.

Because that's for Minecraft Java version. Since your Minecraft Bedrock is programmed differently than Java version, it is impossible to say to join Java Version Server.

It's like asking, why can't analog FM radio receive ARD or ZDF?

No because he has Bedrock Edition. Bedrock Edition works differently than the Java version, so you can only join Minecraft Server that is intended for Bedrock Edition. With the PC server (such as GommeHD, Bausucht, Griefergames etc… "you can unfortunately forget under Bedrock Edition. That is like trying in vain, for example via Fortnite, to join Minecraft's GommeHD server and I wonder why it doesn't work.
