In a special report from Haiti, Nick Davis follows a French charity that is giving free phone calls to victims of the earthquake and providing crucial communications for the relief agencies that have come to help them.
When disaster strikes the first instinct is to check on loved ones - but how, when there are no telephones? And how to co-ordinate relief efforts? Re-establishing phone links is vital and that's why Telecoms Sans Frontieres (Telecoms Without Borders), who perform that role, are among the first into any disaster zone.
Haiti, in the aftermath of its devastating earthquake, is their current challenge.
Nick Davis has been watching as loved ones are connected and rescue services given the technical help they need to work effectively.
