The Handy smartphone device, offering free phone calls and data, is on schedule to be in 1 million hotel rooms around the world by the end of this year. The devices are familiar to visitors in Hong Kong where Tink Labs, the company behind Handy, is based.

The smartphone allows visitors to make unlimited local and international calls as well as use data on the phone. Travelers are able to create a WiFi hotspot to use on other connected devices like a traveler’s own smartphone, iPad or laptop.

“We’ve been seeing a rapid uptake of Handy devices and are on track to exceed our global expansion plans for the year of placing units in 1 million hotels,” said Terence Kwok, chief executive officer and founder, Tink Labs. “Hotel guests enjoy being able to make free calls, while receiving insights that allow them to live like a local. Meanwhile, hoteliers benefits from being able to stay connected to — and improve the experience of — their guests, resulting in increased sales of hotel services.”

As part of Tink Labs’ expansion, the company aims to have its devices in 500,000 European hotel rooms, a quarter of which will be in the United Kingdom, by the end of 2017. To date, the device is already available in 20 major cities and used by nearly 25 percent of London’s hotels.

The smartphones, free for guests, can be customized to provide hotel information such as restaurants and spas, including pushing through offers on the phone. The company says this not only increases revenue from guests, but also guest approval for properties adding that the phones are a must-have item.
