No, at least not with mSpy. While some apps might require you to be on the same Wi-Fi network to activate the cell phone remote camera, mSpy lets you do so from anywhere in the world. Seriously. Whether they’re at a friend’s house down the street or halfway around the world, you can activate the camera remotely. There is no requirement to be on the same network. In fact, they don’t have to be on Wi-Fi. As long as they’re connected to the Internet via 5G or LTE, you’re good to go.
