Let agents send/receive SMS using your old Android phone

What it does

A small, self-hostable server that gives an AI agent a real phone number. SimLink relays SMS through an old Android phone + a prepaid SIM you control, over MCP (Claude, ChatGPT, Cursor, and more).

In the maker’s words, at launch

While playing with agents I realised it might be quite handy if they could get access to OTP codes. And while at it, why not give them ability to send the SMS as well. Twillio is expensive and annoying to set up for my taste. I vibe coded simple Android app that can read/send SMS and simple relay server that…

  Beeper Mini – iMessage client for Android2023 · beeper.com · ▲1,521

  Hi HN! I’m proud to share that we have built a real 3rd party iMessage client for Android. We did it by reverse engineering the iMessage protocol and encryption system. It's available to download today (no waitlist): https://play.google.com/store/apps/details?id=com.beeper.ima and there's a technical writeup here: https://blog.beeper.com/p/how-beeper-mini-works. Unlike every other attempt to build an iMessage app for Android (including our first gen app), Beeper Mini does not use a Mac server relay in the cloud. The app connects directly to Apple…

  I kept missing when my Codex agents finished, so I built relayd — a mobile dashboard that sends push notifications and lets me continue agents from my phone. Free tier available. Would love feedback.

  SimGate2025 · simgate.app · ▲6

  Hi HN, I built a small developer tool called *SimGate*. Problem: most SMS APIs (Twilio, etc.) charge per-SMS. For small projects, prototypes, or local businesses, this adds up quickly. What I made: - An Android app that connects your phone to the cloud via WebSocket. - A simple REST API where you send JSON (`deviceId`, `phoneNumber`, `message`). - Your phone sends the SMS using its own SIM plan — no extra per-SMS fees. Use cases: OTP codes, alerts, internal tools, or any project where you just need reliable SMS without provider costs. Stack: Node/Express + Websockets (backend). Demo &…

  I built a tool to create AI agents that live in iMessageJan 2026 · tryflux.ai · ▲54

  Hey everyone, I made this thing: https://tryflux.ai/. Here's a demo video: https://screen.studio/share/1y2EnC26 Context: I've tried probably 15 different AI apps over the past year. ChatGPT, note-taking apps, productivity apps, all of it. But most of them are just clutter on my iphone. They live in some app I have to deliberately open. And I just... don't. But you know what I open 50 times a day without thinking? iMessage. So out of mild frustration with the "AI app graveyard" on my phone, I built Flux. What it does: - You describe a personality and what…
