An initiative to bring internet access to the "next five billion" people has been launched by Facebook founder Mark Zuckerberg.
The social network has teamed up with Ericsson, MediaTek, Nokia, Opera, Qualcomm and Samsung, among others, to lower the cost of mobile data.
The group said
it wanted to help those in developing countries to become part of the internet community.
But one expert said those nations had "other priorities" to deal with first.
Mr Zuckerberg said the goal was to make "internet access available to those who cannot currently afford it".
