Here's what you can do in Stick RPG that might relate to your question:
* Communicate: The primary way to communicate in Stick RPG is through the "Chat" feature. It's accessed by pressing "C". This allows you to interact with other players, but it's more like a text-based chat than a phone call.
* Get a Job: You can get jobs to earn gold and progress in the game. Some jobs might involve using technology, but not cellphones specifically.
Remember that Stick RPG is a retro-style RPG with a focus on simple gameplay and exploration. It's meant to evoke the feel of classic RPGs where technology isn't the focus.
If you're interested in playing a game with modern technology and cellphones, there are many other RPGs available!
