SMS8.io - SMS Gateway & API

SMS8 turns any Android phone into your own SMS gateway. Write a text message on your computer, or trigger one from your own software, and the phone in your pocket sends it from the SIM already inside it — your real number, your existing plan, no per-message gateway fees.

Nothing is rented, rerouted or rebranded. No shared short code, no unfamiliar sender ID. Your customer sees the number they already have saved for you, and they can reply to it the way they'd reply to anyone.

SEND SMS FROM YOUR COMPUTER
Open your SMS8 dashboard in any browser, type the message, press send. Your paired Android phone dispatches it as a normal text.
- Send to a saved contact or to a list you built in your account
- Personalise each text with merge tags from your own CSV
- Schedule an SMS for later
- Choose which SIM sends on dual-SIM and eSIM devices
- Pair more than one phone to the same account
- Read back delivery status and a full send log with timestamps

SMS API FOR DEVELOPERS
Real SMS delivery for your app without opening a carrier gateway account, renting a short code or filing A2P paperwork.
- Clean REST API — one authenticated request sends a message
- Works from PHP, Laravel, Python, Node.js, C#, Java or any HTTP client
- Delivery and status webhooks pushed to your own callback URL
- MCP server for AI coding assistants
- Ideal for transactional notifications, internal alerts and testing

NO-CODE SMS AUTOMATION
Wire text messages into the tools you already run, without writing code.
- Zapier, Make and n8n
- GoHighLevel
- WooCommerce and Shopify order events
- WordPress forms
- Google Sheets — a new row triggers a text message

WHAT SMS8 DOES NOT ACCESS
- SMS8 does not read, receive or intercept incoming messages

- SMS8 does not read the contacts stored on your device — contacts live in your SMS8 account, added by you
- No ads, no third-party trackers, no analytics SDKs

PERMISSIONS
SMS8 requests one sensitive permission: sending SMS. It is used only to dispatch the messages you create in your own SMS8 account, and for nothing else. You'll see an in-app explanation before the request, and you can decline. A foreground service keeps the send queue running while the app is in the background, with a notification you can see at any time.

REQUIREMENTS
An Android phone or tablet with an active SIM, an internet connection over Wi-Fi or mobile data, and a free SMS8 account. Your normal carrier rates for text messages apply.

WHY PICK SMS8
- Your own phone number, never a shared short code
- Sends on the SIM plan you already pay for
- REST API and webhooks for your own applications
- No extra hardware — it runs on the phone you already carry
- Small, focused app that does one job well
