Mobile phone = a tool to survive, to stay in touch, to be connected, to hear the news (bad and good), to be contactable, to call for help, to be able to leave house, to prove one's existence.
We made to date a number of paper mobile phones - they all are accurate copies of the real phones that belong to the asylum seekers we are working with. To each mobile phone only one message is attached - one they would like to be remembered.
