Dearbhla McHenry, a Boston-based Middle East analyst from Pyramid Research, said the mobile phone industry is one of the few sectors that actually seems to be benefiting from Iraq's instability and crumbling infrastructure.
"Iraq's comparatively fast-growing mobile penetration rate is explained partly by the poor quality of the fixed network," McHenry said. "And partly by the very lack of security, which makes investing in Iraq so risky".
