So, I work for a company who had a cell phone out to an employee, who has now become an ex-employee. There was a passcode on the phone, and he has not advised us as to what it is. There are a lot of contacts and what not on said phone, and we kind of need them.
A)Is there a plausible method, T-Mobile sponsored or otherwise, that we can get this information?
B)If we were to switch phones and the SIM card specifically, would it retain any of the information?
