The affordable Lumia 640 (S$299) and Lumia 640 XL (S$429) will hit the shelves in Singapore this Saturday, 18 April.
First unveiled during Mobile World Congress 2015 in Barcelona in March, the 5-inch Lumia 640 and 5.7-inch Lumia 640 XL ships with Windows Phone 8.1 and will eventually be upgradeable to Windows 10 when the new OS from Microsoft is ready later this year.
Both models offer integrated Microsoft Office experiences, OneDrive storage and fast 4G connectivity.
From now to 30 June, the Lumia 640 and Lumia 640 XL will also come with a one-year subscription to Office 365 Personal, which includes the latest Office applications (Word, Excel, PowerPoint, Outlook and OneNote) on the Lumia as well as on one PC or Mac and one tablet.
With the Office 365 Personal installed, users will receive an additional 1TB of OneDrive storage, and 60 Skype world minutes.
To redeem the offer, users will need to download the Office 365 gift app from the Windows Phone Store by 30 June and activate it by 14 August 2015.
