TlUMIAhe growth in uptake of Windows 10 has been driving a wave of interest in the Lumia 640 LTE Dual SIM model. There has been heightened activity in the B2B community in particular as more businesses look to integrate mobile devices with their IT systems and provide CYOD options for customers.

The Lumia 640 and Lumia 640 XL smartphones allow you to have two numbers for one phone and run Windows, so they can easily double-up as a work and personal device. They feature a quad-core processor and come with a one-year subscription to Office 365 Personal, plus 1TB of OneDrive storage and 60 free minutes of Skype Unlimited Worldwide calling per month.
