Cross Mulitplayer Game (Android & iOS)

Hello,
which with plugin or api (sry i am beginner) should i create a mulitplayer game where i can send online messages to the “other” devices? It should be work cross plattforming (Android and iOS) and send messages in realtime.
The messages are something like a position and damage.

Forthermore it should be can save player stats like money and level etc.

It is just possible with a own server?

I hope you can help me :slight_smile:

Check Photon Chat.

thank you :slight_smile:

but, i doesnt search a chat, i search for a android and iOS plugin, which allows to login with GameCenter or PlayServices and to play with each other.

Or does Photon Chat fits anyway?
