Mobile phone service provider Celtel has expanded its roaming service offer to 12 African countries, enabling around half of all African mobile phone subscribers to communicate across national borders, without incurring extra costs.

Celtel's roaming service is now available in Nigeria, Niger, Chad, Sudan, Burkina Faso and Malawi, as well as the Republic of Congo, Democratic Republic of Congo, Gabon, Kenya, Tanzania and Uganda. Launched a little over a year ago, Celtel's roaming service will extend services to a population of nearly 400 million people, living in an area twice as large as western Europe. "This is a feat that not even European firms have achieved," said Anna Othoro, the marketing director at Celtel. Although Celtel is yet to announce an upgrade to 3G services like its competitor Safaricom, market-watchers believe Celtel's strategy could be a high-volume strategy targeting larger numbers of users to use more accessible services.
