No, but Lorazapam stop you worrying about it. Fuck the tin-foil hat off, they can still read your mind...
Plus your emails, texts, phone calls, and everything else. Basically it's useless, but I'm hoping you didn't need me to tell you.
Also wrapping a mobile phone in tin-foil does not make it untraceable. However removing the sim, and turning the phone off does.
No disrespect here MC Hammer, but I don't think the security services are that interested in a 90's pop star, especially a skint one.
