In the early mobile internet partnering with Nokia and Movistar in Spain. We developed a web-based service using the new WAP for Internet connected mobile phones, like the Nokia 7110. The postcards were merely black and white pixelated images with personalized messages you where able to send from your cell phone to your friends via mobile Internet based on a GPRS connection.
The service also integrated SMS text messages for alerts when you receive a new postcard and phone billing payments for premium content.
