Nedagram – Transfer Text Over Sound, when internet isn't available
I’ve created Nedagram that I think it's ready but needs extensive testing before announcing it: https://nedagram.com ## Problem statement: - during Iran internet shutdown, the government cut off phone lines and mobiles (no text or calls). Gradually they opened up landlines and then phones, but still texting/SMS was down with no real internet. - There were still ways to connect through proxies, vpns, DNS tunnels, etc. However, people had no way to send each other VPN config files or proxy urls/passwords/etc (they needed to call and read them over the phone) ##…
