No. It's the worst thing you can possibly do. Android/Apple phones have back doors (if in their physical possession), and the cops/feds have applications to rip the contents of your phone.
So if one wanted to be extra cautious........starting from now, after reading this thread and they went and bought a new android phone, but used the same sim card would the sensitive info transfer to the new phone.
I have been wondering something for a while now. Is it bad practice to use my cell phone for browsing "sensitive" sites and sending anonymous emails? Is it any less secure than a PC? Just wanted some feedback
Thanks for the info, I was wondering the same thing.
