Hello and welcome to BBC Xtra English!
Today Rob and Rasha talk about the importance of mobile phones to people in the developing world.
They are important because there are areas in the developing world where telephone wires cannot reach or people are always on the move, travelling from place to place.
But there are concerns that women have far less access to mobile phone technology than men.
Across the developing world, it is estimated that 300 million fewer women than men own a mobile phone.
A woman in sub-Saharan Africa is 24% less likely to have a mobile phone than a man.
In South Asia that figure increases to 37%.
As a result, a new scheme from twenty of the world's largest mobile phone companies wants to half that number within the next three years.
This campaign is also supported by two very high profile women, Cherie Blair and Hilary Clinton.
The campaign is called the mWomen initiative, and it began as a result of joint research between The Cherie Blair Foundation for Women and Vital Wave Consulting.
Cherie Blair told the BBC that the aim was not simply to allow women to have nice chats with their friends over the phone but to actually have access to the important and useful technology available on some mobiles.
She described the mobile phone as a poor person's computer as she feels it helps with literacy, health programmes and projects and also assist women in developing small businesses and get financial independence.
