Real SIM delivery
Messages leave as normal SMS from the phone’s carrier number.
My Sim · My SMS
Send SMS from your own Android SIM.
MySim SMS turns a phone into a private SMS gateway. Your system creates a message, the phone sends it as a normal carrier SMS, and you track delivery from the cloud. Android only.
How it works
Built for OTP, reminders, and business alerts — with your number, your device, and live admin control.
1
Install on Android
Sideload the gateway APK on a phone with an active SIM and log in.
2
Keep the gateway running
Allow SMS, notifications, and unrestricted battery so jobs are never missed.
3
Send via API
Your backend enqueues an SMS job. The phone claims it and sends through the SIM.
4
Confirm success
Poll job status until acked — success means the SIM accepted the send.
Why teams use MySim SMS
Clear control for operators who need local SIM delivery.
API for your backend
Create and upsert jobs securely with a system API key.
Per-user isolation
Each gateway account only sends its own messages.
Live admin console
See online status, gateway state, plans, and activity.
Always-on design
Foreground gateway + battery unrestricted for reliable sending.
Android only
Optimized for sideloaded Android gateway phones — not iOS.
Install the Android app
Gateway phones must stay online with an active SIM.
1

| Phone state | Helps reliable telephony / SIM handling |
