I am 38 years old due to a messy divorce and lost my job I had to get a cell phone on my mother's AT&T plan. I pay my own bill on my phone but being as she is the primary on her AT&T account she can monitor pretty much everything I do on my phone. As a grown man there are naturally some things on my phone that I really don't care for my 60 year old very curious mother looking at pretty much anytime you wants. Is there any way I can block or disable her from being able to monitor my phone?
