My test is ready today.

Can I prevent the intrusion of a Federal Govt digital invasion into my phones, TVs, and wireless network?

It should be simple. The only real test is my willingness to cutoff my digital presence from the universe for an hour or two?

FYI - my daughter did the tinfoil test yesterday. Yes, wrapping your phone in tinfoil will shield it from the cellphone and wireless networks. 

 Remember, your phone may continue to be traceable/accessible by GPS if simply turned off. 

We aren't privy to the true tech capabilities of these devices we never separate ourselves from.
