Here's how to send off-grid, encrypted text messages from an old, junk cell phone, without cell service, WiFi, or satellite.

Where do I get the antennas, batteries & device? I’ve got a few old phones to use.

Checkout the devices on Amazon

Bitchat is an app that does this via Bluetooth. Not setup , just the app .

can also just use bitchat

amazing,but i had to keep looking at it cause i saw my name on that text 😂 lol

😭😭coincidence

What kind of distance do you see with this? Or does it go through the network as normal, but with that in the middle?

@Z_Chylde It hops from one phone to another For it to work over a long distance, a lot of yall would have to have thesame setup within the area

@Z_Chylde ok so in practice this is completely useless thanks

@cyber__razz That's not true at all. Its not easy to make your own stand-alone cell network top compete with big tech But, this is true functionality. Comms that are hardened and uncentralized like this are a great idea, regardless of its lack to perform like what big tech has...

In practice you are walking around with an ugly dongle attached to your phone now if several of these nodes were hosted on say aws on the internet and people could tap in/out of this network anywhere they had an internet connection it might be useful but none of these mesh products actually work in practice

@cyber__razz The use case that I think of would be being able to have your own privatized messaging service that doesn't go through big data and allows communication at least with people you are in a closer proximity to. It would be a hassle, but it also might be life-saving...

What are you thoughts about Reticulum?

nice, useful in 50 meters distance.

What Bluetooth antenna is that?

They did this in Person of Interest 11yrs ago. Season 4. You all should watch.

with meshtastic, you can create a private channel as well. connect that node to serial monitor, where you can see the packets too.

I wan to buy off grid kits
