Support videos posted for the Microsoft Lumia 640 XL
The two handsets were introduced at MWC, and this weekend Microsoft posted some support videos for the Lumia 640 XL. The first video shows the keys and parts of the phone, starting with the volume keys on the right side of the handset. The support video also shows us the power and lock keys. On the front of the phone is the proximity sensor and we are shown the micro USB port on the bottom of the handset.
The second video shows us how to insert a SIM card on the device. The phone has a SIM card slot (two, if it is a Dual SIM variant) under the battery. This means you will need to remove the back cover and remove the cell to access the slot. You have to do the same thing to insert a memory boosting microSD card. If you have the Microsoft Lumia 640 XL on your wish list, get a head start on learning how it operates by clicking the video slideshow below.
