POPTALK

PopTalk aims to solve the world's expensive communication and connectivity problem through a new and innovative way: By letting advertisers rent your lockscreen, you receive credits that you can use to call, text, and get online on your phone -- for free. You can also use your credits to recharge your loved ones’ pre-paid phones with airtime or data. PopTalk’s rates are 50-100x cheaper than calling cards, so your credits will take you far. By unlocking your phone, you can unlock your connections.
