Arduino long distance communication

Hello everyone.
I recently had the Idea to build a lottle "device" that can send/recive a signal and turn on a little LED.

This signal has to travel about 500km, and because I don't have much knowledge aboit arduino when it comes to network/intermet comunication I have 3 questions about this.

  1. Is this even possible with arduino?
  2. What is the "best/easiest" way to do it?
    3What parts would I need?

Thanks already for your answers.

Have a great day.!

I don know what a "lottle" is.
Wifi if you have it available.
Cellular if no wifi is available.
