Taiwan-based Acer has announced an entry-level Windows Phone handset at the Mobile World Congress (MWC) 2015 and the USP of this device is that it promises a one-click upgrade to Microsoft's Windows 10 platform when it is released later this year.

Termed the Liquid M220, Acer's new Windows Phone is confirmed to go on sale in Europe for as low as €79 (£57, $88) according to a PC World report. The phone will also be launched in the Middle East and Africa.

As of now, the Acer Liquid M220 runs on Windows Phone 8.1 out of the box along with Cortana and OneDrive.

Acer also launched the Liquid Leap+ wearable that syncs with Windows Phone 8.1.

Spec-wise, Acer's Liquid M220 comes with a 4in capacitive touchscreen supporting multitouch. The low-cost handset is driven by a 1.2GHz dual-core processor, 512MB RAM onboard and 4GB internal storage.

Acer's Liquid M220 also incorporates a 5MP rear and a 2MP front camera, and offers 3G, Bluetooth 4.0, Wi-Fi and microUSB connectivity options.

Another important feature is its dual SIM card support.

Though the technical specifications of the device are not as great as compared to current smartphones, first-time users could be drawn towards the device, especially since Acer has promised the Windows 10 experience.

The handset will be up for sale in April 2015. With various European markets known to accord priority to value-for-money/low-end devices, it remains to be seen if the Liquid M220 gets accepted in these countries.
