Setup, Compatibility & Care
To begin using your SMART.4, insert your NanoSIM card and MicroSD card (up to 64 GB) into the designated slots. Follow the on-screen prompts to set up your Android 10 environment and connect to your Wi-Fi network. For long-term care, ensure you keep the USB Type-C charging port free from debris. Because the device is IP54-certified, it is splash-proof, but it should not be submerged in water. Regularly clean the screen with a dry, lint-free cloth. Consult the included training book for step-by-step instructions on configuring NFC for contactless payments.
