Microsoft Lumia 640

3.7/10 💬 Comment

Good Windows Phone phone with 1.2GHz Quad-core processor provides good performance and great system execution of the Microsoft Lumia 640 (Dual-Sim 3G).

An advantage of the Microsoft Lumia 640 (Dual-Sim 3G) is the possibility of using two mobile carriers, a Dual-SIM device with two SIM card slots.

Good connectivity of this device includes Bluetooth 4.0 + A2DP, WiFi 802.11 b/g/n [wifi4] (2.4GHz), but it lacks NFC connection.

Including the battery, the Microsoft Lumia 640 (Dual-Sim 3G) phone has 145 grams and it's a very thin device, only 8.8mm.
