Core Concepts
SMS Gateway
A system that routes SMS messages between applications and mobile networks, enabling programmatic sending and receiving of text messages.
An SMS gateway is a service or device that acts as a bridge between software applications and the mobile telephone network. It allows businesses and developers to send and receive SMS messages programmatically.
Traditional SMS gateways route messages through telecom operators' SMPP connections. MySMSGate takes a different approach — it uses your own Android phone as the gateway, sending messages through your existing SIM card. This eliminates carrier fees, 10DLC registration, and monthly number rental costs.
Types of SMS Gateways
- Cloud-based — Twilio, Vonage, Plivo (rented numbers, per-message fees)
- Hardware — GSM modems with SIM cards (upfront cost, maintenance)
- Phone-based — MySMSGate (your Android phone + SIM, lowest cost)
Key Components
