Talking without credit or internet

What it is

Messages, voice notes, walkie-talkie and SOS that travel from phone to phone between ERERE people, even when nobody has credit or signal.

Why it exists

Being able to talk shouldn't depend on everyone's credit. If everyone carries a few of the others' messages, everyone can talk.

How it works for you

Write as usual. With internet the message leaves at once; without it, it travels with nearby ERERE people until someone delivers it or finds internet. When it arrives you see ✓✓.

What you give

A little battery and phone storage to carry others' messages, sealed and unreadable. Below 30% battery your phone stops carrying them: you keep the battery for yourself.

What you get

Others carry your messages the same way.

What you choose

How much space to devote and whether to also use your mobile data for others (off by default).

Honest limits

With nobody nearby and no internet, the message waits for the first encounter. The more people there are, the faster it arrives. Nobody along the way can read it.

Where it stands

Tested in simulation and on a real server. Field testing: the real range of phone radios.
