Forum Thread: Ssd and Email

so first i know how to flip the bits on a hard drive to delete data but is it possible for a solid state drive to do the same or will the same software even work. as for the email part i have a spare actived sims card i want to be able to send emails through text or even command lines (using kali) so if for whatever reason i need to do something remotely from school they're monitored wifi will not be able to see what i'm doing.
