I'd suggest turning PureVPN into a telecom company and invent a SIM card that can automatically let the user surf the internet by using built in VPN as a service/feature with the SIM card.
Little reminder, don't make the VPN service comes with price that they can know, MONEY. And the meaning of price that they don't know are personal data. Ways to make benefits are to collect the user data and use them to earn money -- I mean I know selling personal data is illegal but there must be some legal ways that you can find. It's like 'Dude it's the Big Data Era now, who don't make money with is are totally ediot.'
