About Dual SIM Cards

Models of phones with dual SIM slots can be of three types:
• Passive: they have a single transmission antenna, so they can only have an active SIM card for calls and data.
• Dual standby: can send and receive calls by either card, but when a call is received on one line the other goes into sleep. Only one of the data cards can be used. Normally the second SIM can only be used with 2G connection for voice and the main for voice and 3G data.
• Dual call: These phones can be used to call for both cards at the same time, notifying us of which SIM comes the call and if we want to attend or put it on hold. Keeping two lines active at the same time has a greater impact on the phone’s battery. Only the data connection of one of the cards will be active.

Huawei P9 Lite

Best Dual Sim Smartphone in USA
The Huawei P9 Lite is a phone with aluminum body with good design, and part of the price it has is due to the good finish. There are a lot cheaper phones than this one with similar features, but usually they offer more sober designs, in plastic, or with worse aluminum.
It has a good 5-inch screen, with a good maximum brightness value (470 nits), with a larger phone size than many users will like. The rear camera included is good in good lighting conditions, but at night or interior loses enough quality, although in general are good photos for what is in this range and phone design.
The included processor is a HiSilicon (subsidiary of Huawei) Kirin 650, which is aimed at providing fluidity to the average user than a normal use to the device, and usually that does not include heavy 3D games. The battery life is very good, reaching 10 hours of use in Wi-Fi.

OnePlus 3, a powerful dual SIM mobile phone

OnePlus 3 a powerful dual SIM mobile phone
Undoubtedly one of the best smartphones this year because despite being at a much lower price than the premium terminals of companies like Samsung, LG or HTC is able to compete from you to you with them. It could be said that this OnePlus 3 is the most round terminal that has manufactured the company so far.
I personally liked its completely metallic design and its high performance puts the icing on the cake. It has a camera that offers surprising results and inside we find a processor Snapdragon 820 and 6 GB of RAM. Personally, we are in front of one of my favorite terminals today.

Huawei P9 Dual SIM

Huawei P9 Dual SIM review
Huawei has decided to put on the market a high range focused especially on its camera of photos. It does not leave aside the design in aluminum and a powerful processor Kirin 955 with 4 GB of RAM and 64 GB of storage of series. The processor has a main cluster of four Cortex-A72 cores running at 2.5 GHz, and the second cluster are four Cortex-A53 at 1.8 GHz.
The graphical section is usually the one that lacks the Kirin, which is why it is the one that improves in the Kirin 955, since its Mali-T880MP4 GPU goes from 700 MHz to 900 MHz. It includes a reader of fingerprints in the part Posterior, which although not the ideal location, works very fast in the recognition of footprints.
But as I said, in this phone the important thing is the camera. It is Leica- certified to ensure color accuracy and reproduction, and on the back includes two 12-megapixel cameras. One of them is responsible for capturing the color of an image and the other is monochrome. This has some advantages in the field of color camera design and light capture.
The cameras can optimize the contrast depending on the light conditions, as well as make it easier to make a camera by eliminating color filters. The monochrome camera captures at least three times more light in the scenes than when compared to a single-camera phone, and therefore much more detail of the scene that can be used to improve the sharpness of the image. This arrangement of cameras also allows blur or bokeh effects, simulating by software a focal distance between f / 0.95 and f / 16.

Huawei P9 Dual SIM

Huawei P10 dual sim phone usa 2017 review
The P10 is a phone that takes over from what Huawei did with the P9, with some minor changes. The design is very similar to the iPhone, so in this aspect does not stand out. It is attractive and pleasant to use, but very iPhone, for the good and for the bad, and also because the Huawei interface tries to imitate iOS.
The processor is a powerful Kirin 960 that is quite fluid, with a Mali-G71MP8 GPU at 900 MHz, which includes the new ARM architecture of integrated Bifrost graphics. Besides being compatible with Vulkan, it improves up to 50% of basic graphic performance. The processor is manufactured on a 16 nm FiFET ++ node from TSMC.
The P10 displays are IPS type, a 5.15-inch FHD, with 3200 mAh battery, USB connector type C and fast charge. Huawei has added a 4×4 array of antennas for LTE that allows downloading at gigabit speeds.
The main camera is 12 megapixels with a secondary 20 Mpx monochrome, both f / 2.2- f / 1 .8 aperture in the P10 Plus-, can record at 4K and create depth effects, and is a design that also has developed with Leica. The front camera is 8 Mpx. In general they are good cameras, and it is among the best on the market.

Lenovo Moto G5

Moto G 5th Gen G5 4G LTE Dual Sim
Lenovo continues to improve the Moto series with the Moto G5, which comes in versions with 2 and 3 GB of RAM. The rear cover is made of aluminum, and maintains the impermeability of the terminal. It upgrades the previous model with a Snapdragon 430 octa-core processor, dual SIM slot, and a 2800 mAh battery, with a 32 GB storage and micro-SD expansion.
The smartphone maintains the overall aesthetics of the line, which is quite different from what Chinese brands do. It includes Android 7.0 as standard, is an almost pure Android, so it contains hardly any modifications by Lenovo – some Motorola service and little else. The camera has also improved, although it is still mid-range camera. It is good for photos with good light, fully usable for photo albums.

Samsung Galaxy S7 edge Duos

Samsung Galaxy S7 edge Duos review
The Galaxy S7 is a renewal of the Galaxy S6 with just changes to improve it remarkably. The OLED type display has a lower consumption despite being QHD, with an always active feature configurable to display certain information chosen by the user. Otherwise, it is practically the best screen in a market phone, with a brightness of 500 nits.
The processor is an Exynos 8890, with great processing performance and the Mali T880 graphics. The autonomy is also notably better, standing above other phones with which it competes, but still giving the usual duration of these day phones with heavy use or a couple of days with moderate use.
The UFS 2.0 storage of the phone is ultrafast, with speeds close to 220 MB / s of sequential read and 60 MB / s of sequential write. Samsung has also upgraded the layer of Android customization, which takes advantage of the front fingerprint reader (the right location). The phone also has resistance to water and dust, and has wireless charging next to Wi-Fi 2×2 802.11 ac MU-MIMO.

Moto G4 Plus Dual Sim

Moto G4 Plus Dual Sim review
Moto G4, the fourth iteration of the Moto G series arrives with an improvement in its design, more fine and pleasant to the touch, although it loses the test of water in the process. It also increases in size up to a 5.5-inch screen, with good color reproduction, with a maximum brightness of 600 nits, which will make it look good in broad daylight.
The Snapdragon 617 processor is a good upgrade on the Snapdragon 410 Moto G3, which will give you greater fluidity. Combined with an almost pure version of Android, the only glitches in the performance section come from the need to keep the phone updated to avoid certain problems with the included Android version. Otherwise, it works fine, with 2GB of RAM and 16GB of storage with micro-SD expansion.
The camera is normal and within what you can expect in the mid-range to which it belongs, with some problems with photos with low light (also usual), with a fairly good battery life. For those who want a better camera, they have the Moto G4 Plus model, practically the same phone but with a much better camera sensor and more ideal for lovers of photography.

Honor 5X unlocked smartphone

Honor 5X unlocked smartphone
The Honor 5X is one of the most interesting models of the company, maintaining a careful design in aluminum with a good balance of characteristics. The screen is 5.5 inches with 1080p resolution, with good color reproduction, vivid but with a slight tendency to blue. The brightness is above the 550 nits and the contrast in the 1200: 1.
It has a fingerprint reader on the back, which although not ideal for this type of systems is welcome to include. The Snapdragon 616 processor gives you day-to-day fluency, but for the most demanding users they may fall short, but it is the best you can find on its price. The camera with Sony sensor IMX214 will give quite acceptable results, but without good light can introduce enough noise in the snapshots.
The software includes the EMUI customization layer, similar in iOS aesthetics, and may not appeal to everyone. You can also download and install other app launchers from the Google Play Store and not use EMUI. In general it is a very complete phone, with some improving aspect like the quality of the sound.
