The way we work has changed over the years. Finishing a day’s work doesn’t mean being chained to a desk or cubicle from nine to five anymore. Thanks to technology, our computing devices get more compact and more feature-packed as time goes by, allowing us to be productive whenever, wherever.

The Microsoft Lumia 640 XL Dual SIM offers the mobility and productiveness that hard-working, on-the-go individuals look for in their gadgets.


The 640 XL Dual SIM feels solid and sturdy despite the plastic built. There’s a variety of colors to choose from for the interchangeable rear cover. The simplicity of the black unit that we’ve reviewed blends in perfectly to corporate or formal settings; the orange and blue variants can be a refreshing change in an ocean of black and metallic handsets.

The matte finish keeps the 640 XL Dual SIM fingerprint-free and adds texture for added grip. But if you’re not used to huge phones, you might find this Lumia phone too bulky for your taste.


The large screen real estate can be overwhelming at first, but you’d definitely appreciate the 5.7-inch display when you’re reading PDFs, creating documents, and watching videos. While you’ll surely find no issue when it comes to color reproduction and viewing angles, the 720p screen shows pixelation issues in some areas.

It’s difficult to use the device with just one hand. You’d need your other hand to support the phone in order for you to comfortably navigate around the screen, especially when you’re trying to reach the top part.

Individuals who are always out and about will greatly appreciate the huge display when editing document files, creating reports, and reading text. Posting blog entries when using the 640 XL Dual SIM is relatively easier because of its screen size. The built-in Office tools are a welcome bonus.


Running Windows Phone 8.1 with a 1.2GHz Snapdragon processor and 1GB RAM, the 640 XL Dual SIM provides a smooth experience for basic tasks such as messaging, Web browsing, taking photos, and watching content. It takes 15 to 20 seconds to power up the phone, but aside from that it’s generally lag-free.

The Window App Store, while providing significantly more options, has still a long way to go when it comes to variety and features of apps.


Something you’d definitely appreciate is the 640 XL Dual SIM’s cameras. The 13MP main snapper with German-made Zeiss optics captures decent details when outdoors and under good lighting conditions. It can even shoot high-quality full HD videos, which is way better than the phone screen can display. Understandably, noise is an issue for images taken in low-light settings. The 5MP front shooter takes good images even in low light, which is perfect for your selfies and video-calling sessions.

The Lumia Camera software helped greatly in capturing decent photos. There’s the autofocus feature for your quick snaps or if you want to create a well-composed photograph, the camera also lets you adjust the brightness, focus, ISO, shutter speed, and white balance manually.


One good thing about the Lumia 640 XL Dual SIM is that it comes with a microSD slot, which provides additional storage capacity for the phone’s basic 8GB internal storage. Aside from storing your multimedia files, you can directly install your apps on the SD Card, allowing you to free up your phone memory.


First thing you’ll notice that everything looks bigger. That’s because Microsoft simply scaled up the size of the UI elements to fill the screen. There are no physical buttons for navigation. For you to navigate out of full screen apps, you need to take an additional swipe up to display the navigation buttons at the bottom of the screen. It’s a small detail, but it can be cumbersome at times.

Double tapping the screen wakes up the phone, so you don’t need to reach for the power button every time and lets you power up the phone using only one hand.

Also, there are some cool features that help you do work faster. You can get to any setting quickly using the in-app search or pin your most-used settings to the home screen as a live tile. If you want to control which apps will have access to your phone’s camera, microphone, contacts, messaging, and calendar, you may do so in the apps permission settings.


Thanks to its big form factor, the phone is able to pack a 3000mAh battery under the hood. The 640 XL Dual SIM can last at most two days of heavy usage and more than three days of basic Web browsing, calling, messaging, watching videos, and playing light games. No need to worry on your phone shutting down on you in the middle of a task, giving you more leeway to move around.
