Summary

simhook turns an Android phone with a SIM into an SMS gateway and API for sending and receiving texts. API messages go out through the paired phone's SIM, while incoming messages can be forwarded to the account as webhooks. Signed webhooks report sent, delivered, and failed status changes; they are retried for two days and paused if the endpoint continues failing. The service supports scheduled sends, multiple recipients, and dual-SIM phones, with a SIM selectable per message. A TypeScript SDK supports Node and edge runtimes, and its MCP server provides eight tools for AI agents. API keys can be restricted by scope, including a send-only option. The Android app requires version 8.0 or later and is distributed as a signed APK. The full stack can be self-hosted from one Compose file under AGPL-3.0, which the maker says is free without limits. Hosted accounts currently remain on Free, though paid plans are listed from $12 per month. The maker says the service is not for bulk marketing or messaging people who did not ask to hear from you.

Who it is for
