simhook

Product: SimHook turns an Android phone with a SIM into an SMS gateway and API for sending and receiving texts.
Message routing: Messages sent through the API go out through the paired phone's SIM, and received texts can be forwarded to the account as webhooks.
Delivery tracking: The service reports sent, delivered, and failed state changes through signed webhooks.
Scheduling and batches: The product supports scheduled sends and sending to multiple recipients, with pricing limits of up to 2,500 recipients per send on Scale.
Dual SIM: Dual-SIM phones are supported, and a SIM can be selected per message.
Integrations: The TypeScript SDK supports Node and edge runtimes, and the MCP server provides eight tools for AI agents; the maker documents setup for Claude Desktop, Cursor, and Claude Code.
API keys: API keys can have send, read, devices, and webhooks scopes, and a send-only key can send without other access.
Webhook behavior: Signed webhooks are retried for two days and paused when the endpoint keeps failing.
Android requirements: The app works on Android 8.0 or newer, is distributed as a signed APK, and updates itself after the user approves installation.
Self-hosting: The full stack can be self-hosted from one Compose file under AGPL-3.0, and the maker says self-hosting is free with no limits.
Hosting and data: The hosted service runs on Hetzner servers behind Cloudflare, with nightly database dumps; Firebase Cloud Messaging pushes contain no message content.
Intended audience and limits: The maker says SimHook is not for bulk marketing or texting people who did not ask to hear from you, and advises using a business SIM for real volume.
Paid plan availability: Paid plans are listed, but the maker says they open soon and every account is on Free until then.
