As part of their latest update, Nimbuzz (www.nimbuzz.com) has introduced VoIP calling to allow users to buy NimbuzzOut credits and make cheap international calls to mobile and landline over WiFi or 3G, using your Windows Phone 8 device.
The 1.1.5 update includes NimbuzzOut, a guided tour, some bug fixes, and overall performance improvements.
If you're not familiar with the brand, Nimbuzz is a popular smartphone messenger app available on all mobile platforms, as well as on Windows and Mac, that lets you send unlimited chat messages and share photos and videos. The Dutch company, now headquartered in India, claims to have over 150 million registered Nimbuzz users.
NimbuzzOut is their VoIP calling platform that allows Nimbuzz users to make international calls at prices far below conventional rates. You could pay as you go for the calls or subscribe to even cheaper minute packs. Just like other VoIP calling services, Nimbuzz-to-Nimbuzz calls are obviously free.
You can download Nimbuzz for free from the Windows Phone Store or point your mobile browser to get.nimbuzz.com. While Nimbuzz is available for both Windows Phone 7.x and Windows Phone 8, the VoIP calling is available for Windows Phone 8 devices only.
