The Kis runs Android 2.3 (Gingerbread) and has an 800Mhz processor inside its 114.3 x 61.6 x 11.5mm frame, weighing 120g.
Aimed at the budget end of the Android market, the phone has a 3.2MP auto-focus camera with digital zoom, and pictures can be displayed on its 3.5-inch HGVA screen.
Others features include 512MB of internal memory, a 2GB micro SD card, Bluetooth 2.1, WiFi and access to the Google Play market for apps, games and other content.
The Kis is available now exclusively from Virgin Media, offered on pay-as-you-go for just £49.99 when purchased with a £10 top-up.
This marks the second smartphone launched by ZTE in partnership with Virgin Media, following the arrival of the ZTE Tania Windows Phone earlier in the year.
Virgin Media director of mobile Jamie Heywood said: "With the Kis, ZTE has designed a handset that meets customer requirements for a rich Android experience at a very affordable price for PAYG customers."
Heywood added: "With plentiful features and an abundance of apps to choose from through Google Play Store the ZTE Kis certainly delivers on that. We're bundling in a huge amount of data to complement this Android handset for our PAYG customers.
"This is yet another example how Virgin Media is raising the bar in the mobile market because we know how much our customers love to be connected no matter where they are without worrying about expensive bills."
Wu Sa, the director of mobile device operations at ZTE UK, added: "The launch of the ZTE Kis is a further demonstration of our commitment to building the ZTE brand in Europe and the UK across a number of price points and operating systems, which will continue with new devices throughout the remainder of 2012 and in 2013.
"It is also an example of our commitment to providing our customers with quality devices at affordable prices under the vibrant ZTE brand proposition."
