Most Gs-Cam models allow only one active connection at a time. If a second phone tries to connect, the first is disconnected. You can re-enter the same code on the second phone after the first disconnects.
Be cautious when purchasing activation codes from unverified online sellers. Ensure you are using official or reputable sources to avoid software that could harm your device or expose your network. To help you further, could you let me know: Enter Gs-Cam Activation Code
