BLU Diamond M 4GB Smartphone (GSM Unlocked)

Stay entertained while on-the-move with this versatile smartphone, which runs an intuitive Android operating system that gives you easy access to your favorite social media and streaming apps. It also comes packaged with a screen protector and silicone case that guard the phone against scratches, bumps, and drops.

Smooth, Fluid Performance

Switch from taking phone calls to checking your work email to watching YouTube videos without skipping a beat. This phone’s snappy processor balances the workload among its four independent cores to keep everything running smoothly as you juggle apps and tasks.

Dual Cameras

For quick selfies or video chats with your friends, use the front-facing 2MP camera. When you want to capture moments in sharper detail, use the more powerful rear-facing 5MP camera, which has an LED flash for low-light settings. The rear camera can also record video in 1080p Full HD resolution, which looks great when you play back the footage on an HDTV.
