A story in TOI notes that Airtel has introduced flat roaming charges and free incoming calls across its networks in Africa and South Asia. Even though this currently only appears to cater to its African customers, it's still impressive.
"The newly introduced service will further enhance communication for travellers from Africa by enabling them to access data and SMS, in addition to the currently available voice roaming, at a flat attractive rate whilst travelling within Africa and South Asia," the company said in a statement.
Airtel's African customers need not pay roaming charges on incoming calls while travelling in India, Bangladesh, Sri Lanka and 17 African countries.
I guess this is the next logical step after "One Nation, One Network". According to a Kenyan website, the African countries are Burkina Faso, Chad, Democratic Republic of the Congo, and Republic of the Congo, Gabon, Ghana, Kenya, Malawi, Madagascar, Niger, Nigeria, Rwanda, Seychelles, Sierra Leone, Tanzania, Uganda and Zambia. I guess all those IPL players from South Africa will still have to keep an eye on their bills.
