How to install the Ozeki SMS Client on Android
The following video tutorial takes you through the steps of Installing the Android SMS Client software on your Android mobile. Note, that you will need to download the Android SMS app from android-sms-gateway.com. After installation make sure you enable the necessary permissions for Ozeki app. This will enable the app to run seamlessly in the background.
Installation steps
Open the Android SMS Gateway download page in the phone’s browser. Download the Ozeki SMS Client APK installation package. Wait until the download finishes before opening the file.
Open the downloaded APK from the browser notification or Downloads folder. Android may display a security prompt because the app was not installed from Google Play. Continue to the installation settings when prompted.
Tap Settings in the Android security warning dialog. This opens the permission page for the app that downloaded or opened the APK. The next step is to allow that app to install external applications.
Enable Allow from this source or Install unknown apps. This temporarily authorizes the browser or file manager to install the Ozeki APK. Return to the installation screen after enabling the setting.
Android may warn that installing apps from unknown sources can be unsafe. Confirm the warning only after verifying that the APK was downloaded from the official source. This allows the Ozeki SMS Client installation to continue.
Tap Install to copy and install the Ozeki SMS Client on the phone. Keep the phone unlocked and wait for Android to complete the process. When installation finishes, select Open to launch the application.
Android or Google Play Protect may scan the newly installed application. Allow the scan to finish so the installation can be reviewed for potential risks. If the official Ozeki application is confirmed, proceed with the installation.
If Play Protect displays a warning, select Install anyway for the verified Ozeki APK. Use this option only when the file came from the official Android SMS Gateway site. The application can then be installed and started normally.
Launch the Ozeki SMS Client from the installation screen or app drawer. The application provides a local web interface and HTTP API for SMS sending. Keep it installed on the Android phone that contains the SIM card.
In Ozeki SMS Client, start the HTTP Service from the main screen. The service listens for web requests sent to the phone over the local Wi-Fi network. Note the displayed IP address and port for opening the browser interface later.
Accept the requested Android permissions when the application asks for them. These permissions are necessary for sending SMS messages and maintaining service operation. Without them, the HTTP interface may be available but cannot send messages correctly.
Open the Android application settings for Ozeki SMS Client. Review the permissions, battery, and restricted-settings options available for the app. Configure them so the gateway can continue working in the background.
Enable restricted settings for Ozeki SMS Client if Android blocks sensitive permissions. This makes it possible to grant the app the access it needs for gateway operation. Return to the app’s permission page once the setting is enabled.
Grant the SMS permission to Ozeki SMS Client. This permission allows the Android phone to submit outgoing SMS messages through its SIM card. It is essential for messages sent from the browser or HTTP API.
Grant camera permission if the application requests it for QR-code or setup functions. This can simplify connection or configuration tasks within the Ozeki application. The core SMS sending workflow still depends primarily on SMS and network access.
Set battery usage for Ozeki SMS Client to Unrestricted or disable battery optimization. This prevents Android from stopping the HTTP service while the phone is idle. The gateway can then remain reachable from the browser for longer periods.
Verify that the HTTP Service status is shown as running in Ozeki SMS Client. Use the displayed local IP address and port as the browser access address. Ensure the phone stays connected to Wi-Fi while you send SMS messages.
Send SMS from your PC
Enter the phone’s HTTP service address into a browser on the same network. Sign in to the Ozeki web interface using the configured credentials. Successful login confirms that the browser can communicate with the Android gateway.
After signing in, review the dashboard to confirm that the SMS gateway is online. Use the available menus to compose messages, inspect logs, and configure the service. The dashboard is the central browser-based management interface for the phone.
Open the SMS sending page and enter the recipient phone number. Type the message text, then submit the form to send it through the Android SIM card. The Ozeki Client forwards the request to Android, which transmits the SMS over the mobile network.
Open the sent-message log after submitting the SMS. Check the recipient, message content, timestamp, and delivery or submission status. This log helps verify that the browser request was processed by the Android gateway.
Use a curl command from a PC or script to call the phone’s HTTP API. Include the gateway address, authentication details, recipient number, and message text. This approach is useful for automation, integrations, and application-based SMS sending.
Check the sent-message log after submitting an SMS through the HTTP API. Confirm that the API request created an outgoing message with the expected recipient and content. Use the status entries to troubleshoot authentication, connectivity, or mobile-network issues.
