A mobile network that allows users to donate 10% of their bill to an organisation or charity of their choice has launched in the UK. The People's Operator (TPO) will also donate 25% of its profits to charities, including the NSPCC and Childline. Chairman Andrew Rosenfeld said he hoped TPO could spread internationally. The network, which went live on Monday, will initially operate as a pay-as-you-go-only service, with contract options becoming available early next year.
