Why Does “Invalid SIM Card” Appear on SIM-Free Cellular Cameras?

If you see “Invalid SIM Card” when scanning the activation code on your SIM-Free Cellular Camera, the camera may still be linked to another GardePro account.

To resolve this:

  • Press the MENU button on the camera.
  • Select Cellular Info and wait a few seconds for the information to appear.
  • Take a clear photo of the screen, making sure the IMEI number is visible.
  • Contact the GardePro Support Team and attach the photo. Please let us know that you are seeing the “Invalid SIM Card” message.

Our R&D team will remotely remove the camera from the previous account. Once it has been removed, you can scan the activation code again and activate the camera normally.

Note: This message usually means the camera is still linked to another account. It does not necessarily indicate a problem with the SIM card, so replacing the SIM card is normally not required.
