Mobile Application Peer-to-Peer Communication

I ask the question because I don't even know how to ask it to my dear Google friend, and when I try to ask, no proper answer returns.

So I want to build a native app (let's call it TheApp) which deals with some data from users (name, location, etc. and some specific data created and used within the app). I don't want to centralise TheApp's users' data in my servers, I want the user's data to stay in the user phone, and find a way to communicate it to somebody else's phone without going through any kind of server. I thought it looked like how the SMS works : there are messages on two phones and there isn't any server in between stocking or intercepting the messages, is it ?

So the direct question is : can we make two (or more) phones exchange pieces of data with no server in between ? Can we do it either through cellphones network, either through 3g/4g/5g, either through internet ?

Sorry if the question seems odd or trivial, or if I use wrong words to describe it, but I have no knowledge in the field as you can see...

Thanks !

SMS is an overkill here. Take a look at WebRTC Data Channels, which is a technology for peer-to-peer communication. It has native iOS and Android support and, if you happen to need it later, even users running desktop browsers will be able to communicate with mobile users.
