UK consumers are being given the opportunity to sign up for free mobile broadband, on the proviso they agree to view daily advertising content.
Virtual mobile operator Samba - which provides services using Three's network - is giving consumers the chance to use a dongle without a monthly or daily subscription.
Consumers are initially required to pay a one-off £2.99 start-up fee, plus £2 postage for delivery of their USB modem.
Once in possession of their dongle, they are required to watch video adverts online to top up their usage allowance.
ISPreview.co.uk Editor Mark Jackson noted that such schemes tend to be "quite attractive" for casual broadband users.
However, he warned that they "have a habit of failing to return enough income to sustain themselves".
"Meanwhile crafty internet users almost always find clever ways to trick such systems into giving them credit without having to watch the ads, although that hasn’t happened to Samba yet," Mr Jackson told the news provider.
