Why Does “Invalid SIM Card” Appear on My Cellular Camera?

Most GardePro cellular cameras come with a preinstalled SIM card. Some models are SIM-locked, meaning they only work with the SIM card provided by GardePro.

For example, the X66 Pro (X66GPL-DXA) is a SIM-locked model and does not support third-party SIM cards.

If you see “Invalid SIM Card,” it usually means the original GardePro SIM card has been removed and replaced with a third-party SIM card. The camera cannot recognize or operate with an unsupported SIM card.

How to Resolve the Issue

  • Check whether your camera is a SIM-locked model.
  • If it is, make sure the original GardePro SIM card is installed.
  • If the original SIM card has been lost or damaged, please contact the GardePro Support Team to purchase a replacement.
