"How to Connect an Android Phone to On-Chat"
"Connect an Android phone with a local SIM card to On-Chat to send and receive SMS for your contacts. One phone covers a country's message volume."
Introduction
An Android phone with a local SIM card is the simplest way to send and receive SMS messages through On-Chat. No enterprise SMS account is required — just a compatible phone and a local SIM for your country.
Step 1: Prepare your Android phone
Get an Android smartphone (Android 5.0 or higher). Insert a local SIM card for your target country and ensure the phone has an active internet connection. SMS functionality must be enabled on the SIM.
Step 2: Install the On-Chat companion app
Download the On-Chat Android companion app onto your phone using the link provided in your workspace. This app bridges your phone's SMS inbox to the On-Chat platform.
Step 3: Add the Android Phone channel in On-Chat
In your On-Chat workspace go to Settings → Channels and click Add Channel. Select Android Phone from the list of channel types.
Step 4: Pair your phone
Follow the on-screen pairing instructions — typically scanning a QR code from your phone's companion app to authenticate the connection.
Step 5: Send a test message
From your On-Chat inbox send a test message to verify that outgoing and incoming SMS are flowing correctly through the connected phone.
Step 6: Scale by country
If your volume exceeds one phone's capacity, you can connect additional Android phones. On-Chat recommends one phone per country to match local SMS regulations and delivery rates.
