SNAPDRAGON 200/400 & DUAL-SIM SUPPORT
Windows Phone 8.1’s support for Qualcomm’s Snapdragon 200, 400, and 400 LTE chips and dual SIM cards enables OEMs and ODMs to make more affordable (and yet high-quality) smartphones. The two good examples at this early stage are Nokia’s Lumia 630 and 635. The single-SIM, 3G-only version of the 630 is going for just US$159; the Lumia 630 Dual Sim costs only US$10 more. And for US$189, you can get the Lumia 635 that supports 4G LTE.
VPN support is just one of the many new enterprise features in Windows Phone 8.1. The US$169 Nokia Lumia 630 Dual Sim is the first dual-SIM Windows Phone 8.1 handset.
