I have my old smartphone with me, with the old sim card still inside. When I received that phone 4 years ago, it was locked by my cell phone company. However, I am not using it at the present moment, since I got a newer cell phone (with a new sim card) with the same company.
I turned off the wifi on the old cell phone; also, it is not on the network anymore since my number was transferred onto the new cell phone. So, is it possible for my company to actually access data since it was a locked phone?
For example, if I took a video with my old cell phone, would the company (or anyone else) have any way of tracking or getting a hold of my videos (among other things)? In other words, could anyone ever get a hold of the content of my old cell phone remotely?
