I am trying to edit the network settings on my Vigi C540-4g however when on the security manager app it is showing the following error. 

When using TP-Link ID to manage the camera, you can only view the camera's network settings, but cannot modify the network parameters.

I am trying to chnage the settings as i have a pay as you go sim card in the camera with an unlimited data plan however the camera is not using the plan and is draining the credit after a few minutes of using and then stops working.

any help would be greatly appreciated.
