Are you asking how to dispose of unwanted electronics, or how to not use
them?
If the former, give them to someone else. If no one else wants it, give it to
someone who takes electronics for recycling. Best Buy does this.
If the latter... just don't turn it on? I don't know what else to tell you.
What, are you incapable of telling someone that you choose not to use your
phone?
On a side note, why does anyone need your consent to buy you something?
That's an awfully strange authoritarian perspective.
