The BLU Win HD Windows Phone with Dual SIM LTE may be the best contract bargain yet

Back in 2014, BLU became one of a handful of new white-label manufacturers to add their services to the Windows Phone ecosystem. Offering low cost but eye-catching phones to consumers, companies like BLU brought something other than Lumias to those in the US. Perhaps more importantly, they finally offered a vision of unlocked, carrier free devices, giving consumers the ultimate choice. The BLU Win HD was a strong first effort. With its bright colors and bold design, the Win HD had a lot of potential. However, lacking 4G LTE data is a major setback for devices in the US, where the speedy standard is found on the most basic phones. Due in part to the chipset used at the time, this was one of the roadblocks keeping the otherwise stellar Win HD out of some people's hands.

New, much better processor The specs in the BLU Win HD LTE at first blush do not read as anything incredible. However, there is a subtle difference found in the Qualcomm Snapdragon processor that makes this phone very interesting. BLU Win HD LTE (2015) Colors: Grey, White, Orange, Yellow

I am going to cut to the chase here: I have been using this phone for the last week, and it is a fantastic improvement from the original Win HD from 2014. Here are a couple of things that I immediately love about this phone. Dual SIM with AT&T and T-Mobile 4G support This BLU Win HD finally has LTE and yes, it works on AT&T and T-Mobile for those speeds (MetroPCS, Cricket Wireless, Simple Mobile, and Net 10 too, although I have not yet tried them yet). In fact, since it is a dual-SIM phone I was able to put both AT&T and T-Mobile SIM cards in the device at the same time. Keep in mind that while dual SIM is common in other markets, it is unusual for those in the US. It is finally nice to see it in action. This is how it works. Insert both SIMs (you may need a micro-SIM adapter if currently using a nano-SIM card) and the phone will ask you to pick the configuration settings matching that carrier. In my case, I chose AT&T and T-Mobile US respectively. You can then choose which SIM handles data, and you can change this at any time (although the radios will reboot momentarily).

Since Windows Phone can handle dual SIM with ease, phone calls and SMS can go to both SIMs at the same time. It is exactly like having two phones in one. 4G LTE data, however, only goes to one SIM, which makes sense if you think about it (you really can't have two data streams in at the same time, plus that would quickly kill the battery). So if this week you want your T-Mobile SIM to handle data, you choose that one, or swap to MetroPCS the next week if you want, all within the OS settings.

Slick design BLU is not using the same design as they did last year. Instead, this model has a metal strip around the front bezel and some other minor cosmetic changes like 'cross-hatched patterns' etched into the side buttons. Currently, I have the black version, which is very conservative looking (and yes, it bears a striking resemblance to a certain HTC phone). However, for my personal device, I will likely opt for the bright yellow or orange because they are just awesome. Even the white one stands out in a good way.

The quality of the build for the phone is also very good. No creaks, smooth finish and it feels great to hold with its soft touch paint on the back. Oh and the BLU Win HD finally has backlit keys on the front now. They still lack haptic feedback, but the fact they light up now is a big step in the right direction.

Seems faster The Windows Phone OS handles 1.2 GHz speeds quite well. However, up until now we have not seen it run on the newer, beefier Snapdragon 410 processor with peppier Adreno 306 GPU. Let me tell you: it gives the Windows Phone OS just enough breathing room to make a big impact on usage. Fewer lags, quicker app launches and just a smoother experience. Yeah, I could use the older Snapdragon 400 devices, but I did feel the slowdown. The 410, though, is the perfect fit for Windows Phone and makes the Win HD LTE feel like a different phone altogether. BLU is also boasting that this is a 64-bit processor in their sales materials as improving battery life too.
