Microsoft’s most affordable 4G LTE Lumia 550 smartphone with Windows 10 is now available for $139 USD in select markets starting today. The Lumia 550 sales have currently started taking place in Europe. However, the device will soon be expanded to other markets.

There is a Glance screen on the phone; wherein you would see the calendar appointments, notifications, time, and date, displayed in standby mode. A removable 2100mAh battery promises to deliver 28 days of standby time.

With support for 4G LTE, Lumia 550 works with a download speed of up to 150Mbps. Few other connectivity options include A-GPS, FM radio, Wi-Fi 802.11 b/g/n with hotspot functionality, USB 2.0 and Bluetooth 4.1.
