  4. android-sms-gateway

    The SMS Gateway for Android™ app enables sending and receiving SMS messages through an API that can be accessed directly on the device or via a cloud server when direct device access is not possible.

    Project mention: Show HN: Text an LLM at And61493035885 | news.ycombinator.com | 2025-03-16

    I put together this basic service running on an Android phone with a cheap prepaid SIM that supports "unlimited SMS to 20 countries". I considered alternatives like Twilio and Telnyx, but at ~5c per SMS sent or received in Australia, the SMS costs would rack up faster than the LLM costs! Of course, this comes at the risk the carrier disconnects my service.

    I explain it more in the blog post, but the service is just a basic node server that sends the LLM calls to DeepInfra running Llama 3.1 8B. The node server runs in Termux on the phone receiving the SMS, and is relayed to the node server by SMS Gateway for Android[1].

    Tip: you can text "CLEAR" to clear all your past messages from the database so you can start a new conversation.
