Why can't I add the 4G camera to the app?  

1) The camera's battery may be too low, preventing it from turning on. Please charge the camera for 3 hours using a 5V mobile phone charger, then add the camera to the app again according to the instructions in the user manual.

2) The cellular data on the camera's built-in SIM card may have been used up, resulting in a failed network connection. Please contact our after-sales support team; we will provide you with trial data so you can add the camera.

3) Please ensure you are using the SIM card that comes with the camera. By default, the camera only supports the included SIM card and does not support SIM cards from other carriers. If you insert your own SIM card, the camera may fail to connect due to incompatibility.

4) Please ensure you are using the camera in the country where you purchased it and have not taken it to another country. The 4G module built into our standard cameras varies by country. By default, they can only be used in the country where they are purchased. If you take the camera to another country, it may fail to connect due to module differences.

For points 3 and 4, only the Global Version of the 4G camera works in countries around the world and supports SIM cards worldwide. Other standard 4G cameras have restrictions on SIM card compatibility and usage region.

If your camera does not have any of the above four problems but still cannot be added to the app, please contact us for further assistance via email: support@hosafe.com.
