About
SMS8 lets you send text messages from the SIM already in your iPhone & iPad, composed from your computer instead of your handset. Write a message in your SMS8 dashboard — or trigger it from your own CRM or application through the SMS8 API — and your paired phone sends it as a normal text from your real number. Your customer sees the number they already have saved for you, and they can reply to it the way they'd reply to anyone.

HOW IT WORKS
Install SMS8 and sign in with your SMS8 account
Grant SMS sending permission — you'll see a plain explanation before the request
Open sms8.io on your computer to compose and send, or connect your own software with an API key
YOUR NUMBER, YOUR MESSAGES
Because the app uses the SIM already in your phone, recipients see your real phone number and your normal SIM plan applies. Nothing is rented, rerouted or rebranded — no shared short codes, no unfamiliar sender IDs, and no per-message gateway pricing layered on top of the plan you already pay for.
WHAT SMS8 DOES NOT ACCESS
SMS8 does not read, receive or intercept incoming messages
SMS8 does not access your call log
SMS8 does not read your device contacts — 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 account. 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.
WHY PICK SMS8
Your own phone number, not a shared short code
Sends on your existing SIM plan
API and webhooks for your own applications
Works with the phone you already carry — no extra hardware
Small, focused app
