I’m a full-stack developer who’s always looking for simple, affordable tools, especially when building for side projects or indie SaaS ideas.
Recently, I ran into a familiar problem:
Sending SMS through APIs like Twilio gets expensive fast.
Even basic features like 2FA or delivery alerts can become unsustainable when you're paying per message, especially on low-margin or small-scale projects.
That’s when I decided to build SimGate — a lightweight developer tool that lets you send SMS through your own Android phone and SIM card, using a clean API, without per-message fees.
Who is SimGate for?
How does it work?
SimGate connects to your phone via a mobile gateway app. Once paired, you can:
This way, your phone becomes your own private SMS gateway.
I’m keeping the first version lean — just enough to get real use cases working.
Want to try it?
I’ve opened up a waitlist to gather early interest and invite a few testers as soon as the MVP is live.
If this solves a problem for you — or just sounds interesting — you can join here:

Thanks for reading — and if you’ve ever struggled with SMS pricing or built your own DIY solution, I’d love to hear your story in the comments!
