Show HN: Nedagram – Transfer Text Over Sound, when internet isn't available
shayanbahal Wednesday, February 18, 2026
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)
## Solution: - TLdr; A modem: a way to transfer text (e.g VPN config) over phone calls
Here's the github issue for community testings, Please try and let me know what you think: https://github.com/shayanb/Nedagram/issues/5
p.s. there is a CLI version too, would be cool to see what people would do with it: https://www.npmjs.com/package/nedagram
