@reolink-lorenz Can you tell me how the sim card and data card vs cloud are all related? I have 2 cameras I've been using for a couple years with the 5gb T-mobile plan each, never hit the limit. They have their own memory cards in them. Just bought a new cam for a different use and didn't do the card but rather the cloud, and within just a few days I got an email saying that my data usage was at 80%. Also, the cloud account I did was the free storage of 1gb and it's already full, but doesn't seem to be overwriting like I thought it's supposed to. What's going on?
