That's because the Yapa Phone is not connected to a landline, but to the home Wi-Fi network. Parents then set up the device via a smartphone app, which also lets them specify which contacts or phone numbers can be reached. The app also allows them to limit when Yapa can be used, so as not to interfere with children's sleep or study time, for example.
Pricing and availability
The Yapa Phone is currently only available in the United Kingdom, with a launch in the European Union set to follow "soon". The gadget costs £99.99 ($132). Calls between multiple Yapa Phones are possible without a subscription, but calling conventional phone numbers requires a subscription costing £9.99 ($13) per month.
