Inside refugee camps, the smartphone serves as an important lifeline. But how are refugees getting internet access?
At one refugee camp in Calais, France, dubbed "The Jungle" has a unique way of accessing Wi-Fi.
A volunteer organization drives an old blue truck with a homemade antenna known as the Refugee Info Bus into the camp every day. The antenna connects to the mobile network using multiple SIM cards and then beams a Wi-Fi signal to the refugees. The truck uses about 50 gigabytes every two days split among roughly 400 people.
That's the same amount of data used by the average person in a month, but for refugees is a vital connection to the outside world.
