Phone with two radio modules on android. Top smartphones with two SIM cards. Version Zoom. External DSDA modules

According to numerous requests of our regular readers (and we are confident that all our visitors are permanent :)), our today's article will be dedicated smartphones with two radio modules. Smartphones with two SIM cards It is already difficult to surprise someone, almost all manufacturers have begun to issue such devices. But they have one small limitation. You will not be able to call the second phone number if you speak the first. We see that people are looking for these gadgets, but finding such very and very hard.

Have many undeniable advantages:

you are always in touch, both sim cards are active. If one SIM card you have "home", and the second "worker", you will always find colleagues or relatives;
more stable internet work. When talking at one number, the second will receive messages on e-mail or on social networks;
significant savings on calls. Connecting to two different mobile operators, you can reduce your expenses depending on the needs;
mobility. No need to carry two gadgets with you;

Unfortunately, such phones have one unpleasant feature quickly discharged.

But let's talk better about pleasant, namely what popular smartphones with two radio modulus or two active SIM cards Presented today in stores. Manufacturers do not particularly please us with such versions of the phones, find this smartphone really rarely, we tried to take away gadgets that can still be found in stores or buy on Aliexpress.

Let's start, perhaps, with one of the main hits of 2015. ASUS smartphone comes in three different modifications, and, in our opinion, version Ze551ml perfect. This is the embodiment of simplicity and reliability. Lovely screen 5.5 inches, Full HD IPS with Glass Glass Glass 3 and oleophobic poker. In the sun shows sufficient brightness and excellent color reproduction. Cameras also pleased 13 MP main and 5 MP frontal, it is enough for video calls and excellent selfie. Cameras have many settings, so you can create real works of art. Volume random access memory - As many as 4 GB, we could not find applications and games that would "slow down" in work. 32 GB is available for storing personal data, i.e. In addition to a smartphone with two active SIM cards, you get the perfect smart phone with excellent characteristics and with NFC support. The battery is installed with a lithium polymer capacity of 3000 mAh with technology fast charging. In 40 minutes the phone charged to 80% from scratch.

Huawei Ascend. Mate7 Premium.

Trademark Huawei. Not the first year pleases its buyers with interesting innovations, but the most interesting model smartphone with two radio modules We consider Huawei Ascend Mate7 Premium. Stylish design, durable metal case, the frame of the screen is minimal, the screen itself is 6 inches (read also), the sound quality is amazing, simply put, "filling" to the latest technology. Android 4.4 is installed, but the manufacturer promised to update up to 5.0. Fingerprint sensor It did not work correctly correctly, we generally apply skeptically to such functions in the phone, but the manufacturers consider otherwise and do everything to increase the cost of the apparatus. But those who are afraid for their personal data and who has something to hide, perhaps this function is useful.

RAM 3 GB, I would add up to 4 GB to rational decision, but decided that it was enough. Support for LTE networks, Communication quality Excellent, GPS / GLONASS satellites catch quickly and with high accuracy. Supports memory cards up to 128 GB, but some users noted installation capabilities up to 256 GB. Built-in memory 32 GB. The battery in the smartphone is fixed, 4100 mA / h, 2 days of active load withstands calmlyIn addition, it is possible to recharge other devices using a special cord that comes in the kit.

The smartphone is positioned in the premium class, but it lacks something for the speed of work, there are small problems with the company EmUi branded shell. But if it does not scare you, then smartphone Huawei. Ascend Mate7 Premium with two active radio models will become a real find.

The HTC model is already a little outdated, but among what you can choose from smartphones with two active SIM cards, this phone is one of the best. So, what can I offer HTC One M7 Dual. Regarding the capabilities of the device, it is not necessary to deduct much, because Nothing outstanding in the smartphone is not. Unfortunately, there is a limit on the SIM cards: if the first slot supports 2G and 3G networks, then the second works only with second-generation networks. Smartphone is equipped with an aluminum removable rear lidwhich significantly takes the gadget, but at the same time gives reliability and solidity.

When we saw that in the smartphone, the battery is only 2300 mAh, we first did not believe and thought that we were some kind of defective version of the phone, but it turned out that this is a real battery and not joke. The charge is sometimes difficult to hold even in the morning and until the evening. It is necessary to minimize the activity of the use of smartphones or carry in PowerBank pocket.

Cameras in the device are installed, apparently, in order to simply say that they are. Front 2.1 mp, rear on 4 megapixel.

For all other parameters, the usual average phone was turned out for those who need a "dialer", but with two active sim: rAM 2 GBbuilt-in 32 GB, corporate interface HTC Sense. UI has always been a "chip" HTC. We did not arise any problems in our work, but some celebrate the "eternal" problem with the microphone, so choose the device carefully and check directly in the store.

When buying a smartphone from Lenovo, make sure that the K910 model has two letters "S", they mean that we have a smartphone with two radio modulus. The phone turned out to be a classic design, but, nevertheless, calmly copes with everyday tasks. On board good processor with a frequency of 2.2 GHz and 2 GB RAM. Unfortunately, the user is available for storing only 16 GB, so you just advise you to purchase additional map Memory. The screen is excellent, with excellent viewing angles, a resolution of 1080 × 1920 and a diagonal of 5.5 inches, is protected by glass Gorilla Glass 3.. In the hand lies comfortable, the weight of only 147 grams. MicroUSB port supports OTG technology.

Cameras are ordinary - on 13 MP rear and 5 MP front. No outstanding is different, but pictures are quite decent. When working with two radio modulus There were no problems, it's a little inconvenient to choose which card to call, but it is quickly used to get used to it.

Another smartphone from HTC got to us in an article. Users call it one of the best smartphones with the simultaneous operation of two SIM cards. This is a simplified version of the famous company flagship. The device works very stable. We did not notice the failure in our work. It looks very prestigious. There are no significant advantages in it, but it has something special, the perfect combination of price and quality. The RAM is only 1 GB, and 8 GB is available for storing their files, video or photo, memory cards are supported up to 64 GB. The 5-inch screen with a resolution of only 540 × 960, but is performed quite efficiently and does not cause discomfort when working.

In the smartphone used technology HTC BOOOMSOUND.It provides excellent sound quality due to two front stereo speakers.

The rear camera on 8 MP has shown an excellent result, even despite its modest characteristics. Video recording occurs in FullHD 1080p format.

Outcome

Here, perhaps, all that we wanted to tell you about smartphones with two radio modules. It should be determined for yourself, whether you need such a gadget or not. Unfortunately, manufacturers believe that such devices are inappropriate, in some European countries, even legislatively prohibited to use such phones. Perhaps in the future, the situation will somehow change, but today the forecast is negative. Everything rests on the battery, which, as usual, remains weak Party All phones. You may have a mega-class device, but if it is enough for half a day, there is no sense from him. Tell us about your experience in the use of such gadgets, write about them in the comments, and we will definitely create an overview in our following articles.

In 2016, a smartphone with two symcards will not surprise anyone. If earlier such functionality was considered a lot of budget Chinese tubes, now the global giants (like Samsung or Sony) are not neglecting the installation of the second slot into their flagships. Only Apple stands on the side, it seems, not going to go on the market.

At first glance, all smartphones with two characters do not differ in terms of work with networks. But in fact they can be divided into 2 groups: Dual Standby and Dual Active. The main differences between them are that the symcards work alternately in Dual Standby technology, and in Dual Active in parallel, does not depend on each other.

The first technology is easier and therefore occurs most often. In this technologist, the phone is not exchanged by data with tights simultaneously by two sim cards, and does it alternately, then one, then the second. Located in the access area of \u200b\u200bthe towers of this enough to confirm the activity of the subscriber.

The lack of Dual Standby technology is that at the same time send a request from two sims is unable. As a result, when a conversation is being conducted on one sim card - the second is not available. Sometimes it will not be able to get through if one of the cards supports an Internet connection, exchanging with the database of batch data. And if both numbers belonging to one operator are assigned identical IMEI, then at such moments the activity of one SIM card may completely "knock out" other from the network.

For smartphones with two radio modulus (Dual Active Technology), these problems are not relevant. Each Simkart highlighted its own active transceiver, with which it keeps connecting to the base. Accordingly, if you are talking at one number, you can hear and take a call to the second number at the same time. It is a pity, in 2016, such tubes remained a bit.

Two active modules are enhanced by the cost of production, require fine optimization of power consumption, therefore is not popular among manufacturers. Those few smartphones that are equipped with two radio modulus, and which are still relevant in 2016, our material is devoted.

ASUS Zenfone 2 Ze551ml - relatively fresh, and therefore the current, smartphone with two radio modulus. He came out in March 2015, and now the device can be bought at a price of 180 (2 GB of RAM / 16 GB of ROM) to 350 (4 GB of RAM / 64 GB ROM) dollars. In addition to the amounts of memory, the versions of the processors are distinguished. In the model with 2 GB, Intel Atom Z3560 is used (4 x86 kernels, frequency up to 1.8 GHz), with 4 GB - Z3580 (4 x86 kernels, up to 2.3 GHz).

The ASUS Zenfone 2 - 5.5-inch FullHD screen, with an IPS matrix and protective glass of Gorilla 3 generations. The camera is 13 megapixel, with a double flash, f / 2.0 light and autofocus (not laser, usual). The operating system - Android 5, is scheduled to update to the "six".

A 3000 mAh battery is typically for a flat, but considering that 2 modules mean reinforced charge consumption, the time of operation can be called average. Two days ASUS Zenfone 2 will last, only if it is not particularly loaded. In general, the device is balanced, and thanks to the Iron from Intel - also quite fast.

Second smartphone with two simultaneously working radio modulus - Huawei Honor 7. He came out in July 2015, now it can be bought for 350 US dollars. A smartphone on the Hisilicon Kirin 935 chip, which has eight nuclei (frequency - up to 2.2 GHz). RAM 3 GB, built-in storage - 16 or 64 GB. There is a slot for a memory card, it is combined with a second sim card.

The Huawei Honor 7 display is built on an IPS matrix with a resolution of 1920x1080 points, and a diagonal of 5.2 ". The camera on 20 MP has a F / 2.0 lighting, equipped with a phase autofocus and a double flash. Works smartphone running Android Lolipop, you can upgrade to the sixth version. .

The battery is fixed, with a capacity of 3100 mAh. It is enough for 13 hours of reading, 10 hours of video, 4 hours of games or 2 days in standby mode. Huawei Honor 7 is really good, once a flagship gadget from the Chinese manufacturer, and one of the few "clean" two-semen in this category.

Huawei has other products with Dual Active SIM support (almost every model more expensive $ 250 comes in such a modification). But everything is very difficult with the versions: for different regions of the world, they put a radio module, sharpened under the frequencies of a particular market. Among the "Europeans", the other two-sickens of Huaveway are not found.

HTC Desire 700 is a real long-lived: it was presented in November 2013, and on sale appeared at the beginning of 2014. On this moment Its characteristics look relevant only in the budget category. Give $ 165 for a model that is more than 2 years old, somehow sorry, but if you need a telephone with two active radio models, then the choice is small.

HTC Desire 700 operates on a quad-core processor with a frequency of 1.2 Mp. RAM here 1 GB here, for data is allocated approximately 5 GB of only 8. There is a microSD slot. The screen is a five-year 960x540. The camera has a resolution of 8 MP, equipped with autofocus and diode flash. OS apparatus - already outdated Android 4.1.

The battery in HTC Desire 700 is removable, its capacity is 2100 mAh. Little, but for the day of moderate loads enough. But longer - already as it turns out: if both SIM cards are active, the charge is spent quickly.

Lenovo k910ss.

Lenovo vibe. Z K910SS is another not new, but so far a current smartphone with two radio modulus. He came out in September 2013 and became probably the last Lenovo with the support of the simultaneous work of both simkart in transmission mode. The model with two S in the suffix is \u200b\u200ba version for China, which is not so simple, but still real. The issue price is about $ 200.

The smartphone is based on the Qualcomm Snapdragon 800 processor. This is a quad-core chip, a frequency of up to 2.2 GHz, which is the flagship of 2013. RAM in VIBE Z - 2 GB, which even by the standards of 2016 is normal. The files are assigned about 12 GB (out of 16), the memory card slot is missing, but there is OTG.

A 5.5-inch diagonal screen is equipped with a FullHD IPS matrix. Safety glass (Gorilla Glass 3) is present. The camera on 13 megapixel is not remarkable for 13 megapixel: there is an autofocus, there is a flash, video in FullHD writes, the overall quality of the shooting is average. Initially, the Android 4.2 was installed on the smartphone, later the version 4.4 appeared, and the craftsmen ported Cyanogenmod on android database 5.1.

An accumulator for 3050 mAh provides autonomy, which neither to praise is not for anything. 4 hours of games, 8-10 videos, 12 readings, a little more than 2 days in standby mode - typical indicators for most smartphones.

Conclusion

Find the current smartphone with two radio modules is not easy. As the review cocked, all devices with the support of the simultaneous activity of both Simcart were released in 2013-2015. In addition, most of them are or done in China, or for China, or both at the same time.

Considering the tendency, soon the second radio module will completely go into the past. However, if you do not want to skip the call on the same map when the other is active, you can simply set the cross-forwarding. And then the call to the inaccessible number will automatically be redirected to the one from which you are currently talking.

How not to drown in a sea of \u200b\u200btwo-minute smartphones, deal with technologies without a dictionary and without a consultant to choose a good smartphone on 2 SIM cards - read our detailed guide.

Today it is difficult to find a smartphone without the support of two SIM cards than the opposite (the exception is only IOS-devices). Even flagship smartphonesDepending on the market and other criteria, produced in several configurations - with one or two SIM cards. Do you really need to be so necessary for mankind?

Yes. For several reasons.

First, it is savings on the second smartphone: often, moving to a new job, an employee can get a new number - "worker", with relevant profitable corporate tariffs. You can choose a good inexpensive smartphone for the corporate number, and you can deliver a "working" sim card to your regular phone.

Secondly, it is saving on tariffs when calling the numbers of subscribers of other operators. And at least among Ukrainian networks favorable tariffs For such communication, someone simply can leave the favorite operators for calls within these networks. Internet tariffs, like the Internet services themselves, can also be found to this item: some operators have an excellent 3G coating - at least in the subway, even in the mountains in the mountains will still be, pleasant racklessness or other attractive conditions for use mobile Internet. From the other cards, it is simply profitable to call.

And thirdly, 2 SIM can be used with frequent travels, foreign trips, buying cards of local cellular operators - so as not to lose touch on the main SIM and do not deny all the money in roaming.

The item "One SIM card for conversations, the second - for the Internet" is natural, even if not all smartphones support the "Both Cards for 3G" feature. More often you have to assign a map that will be responsible for entering online. Because if you are interested in models in which the Internet connection can be consolidated at both SIM cards, carefully read the phone numbers. From low-cost models, it can be Xiaomi Mi Max, Sony Xperia Z3, Xiaomi Mi Note Pro, Huawei Honor 7, Lenovo Vibe P2 and other smartphones.

By the way, Apple probably, the last brand on the market, which stubbornly does not release smartphones-two-one. All iPhone is equipped with a slot for one SIM card. And whatever the advantages of the iPhone either possessed competitors - there are enough buyers in the world that instead of Apple have chosen the flagship Samsung Galaxy S8 or Galaxy Note. 8 Simply because you can put two SIM-ki.

Although Chinese craftsmen have long invented the adapter, which allegedly will allow two cards on one iphone.

Submarine Stones: Hybrid Slots

Two-sinker - a strong marketing stroke. Noticed that latelyWhich smartphone either take, everywhere there will be support for two SIM with a "hybrid" slot (that is, combined with a memory card slot). And you have to choose: or additional memory, or an additional mobile number. In some models, such a choice is non-critical: built-in 32 or 64 GB of memory with more than enough for the storage of multimedia on the smartphone. But if in a model of only 16 GB of internal memory (or even handicraft 8 GB), two SIM, but a slot "hybrid", be alert - it is better to look for another smartphone.

Why is this happening? 16 GB is the minimum configuration for most even Chinese manufacturers. The minimum means the cheapest. Chinese cheap smartphone In 99.9% of cases work on some of android versions With custom firmware on top of OS. The operating system in itself occupies a lot of space and instead of the declared 16 GB at your disposal, at best, will be 12 GB. Add the weight of custom firmware on top - and answered memory It will become even less. Plus, put a couple of programs, take two or three dozen pictures or short videos - and now the service message "Not enough memory!".

Therefore, if the SIM slot is hybrid, and you really need both SIM cards in the smartphone and for the sake of the memory card you are not ready to sacrifice mobile communications - do not take models with built-in capacity below 32 GB.

Standards and characteristics

To choose smartphone on 2 SIM cards You need to know the database: what are the configurations of two-one and what they differ. Further - proceed which technology is more suitable for you. There is nothing complicated here, only two types:

DSDS (or Dual Sim Dual Standby) means that this smartphone has only one radio module, because two sims cannot fully work simultaneously. The radio module is alone, because the operation of SIM-cards will be alternate: if you are called to one number, the second will be temporarily out of the area of \u200b\u200breach.
DSDA / DSFA (or DUAL SIM Dual Active / Dual Sim Dual (Full) Active) The marking is obtained by smartphones with two radio models that can work in parallel - conveniently if you are from those who always misses important calls over the second line by hanging on the first. In addition to labeling, two radio modulus in the model or one, you can check the trite - a call from one SIM card to another from the same smartphone.

The Internet connection problem is only on one SIM - this is just about phones with one radio module. On models with two radio modulus, in theory, both SIM cards should work with 3G. "Give the one that with two - it is better!", "Think the buyer who is accustomed to quickly make decisions. But do not rush. DSDA phones have their own pitfalls.

Question autonomy

On the one hand, you are always in touch, but on the other, the characteristics "always in touch" and "two active radio modulus" is worth reading otherwise: the smartphone will be faster to spend energy due to the need to keep two radio modulus online at the same time.

So, the smartphone with two active SIM can be discharged faster than the model with alternately active cards. There is a way out: buysmartphones with more energy-intensive battery , energy efficient processor or with a smaller screen resolution (on the backlight of which is the lion's share of charge). Ideally, the battery capacity of a 5.5-inch smartphone with two active SIM should be 3300-4000 mAh (more - better) so that you have enough energy at least one and a day and a day. To save energy, you can also take a model not with Full HD (1920 × 1080 points), but with a HD screen (1280x720 pixels), although it is extremes.

Did you know not only the type of radio modules, but also the operator, whose sim you use, and the type of network to which you are connected, affected by the charge. And even except for two-minute smartphones, there are existed in the world smartphones on 3 SIM cards . Do not ask why. Accept as a given.

Models with two radio modulus can be more expensive. So more carefully with prices. We are not about the transcendent difference, but even among Chinese smartphones, it can be 25-40 USD.

Top 7: Choosing smartphones on 2 SIM cards

Most models in the selection - Dual Stand-BY, then only one sim card will work at the same time. Just because so the devices are easier, cheaper and energy efficient. But the Dual Active models will not leave without attention either.

Price: ~ 500 USD.

SIM format: Nano-SIM.

OnePlus 5T - pleasant shopping If only because his analogs are often worth 100, or even on all 250 dollars more expensive. And you receive a 6-inch smartphone with one of the top processors of 2017 on board - Snapdragon 835, the 8 GB of RAM and 16 MP camera removing in the resolution of 2160p. The capacity of the battery capacity of 3300 mAh is alarming - for a smartphone with 6 inches of this little, especially since you are two-minute.

On the other hand, 3300 mAh can be charged almost for almost an hour faster than 4000 mAh: you can more often to charge and shoot it faster.

Did you know What is the greater the battery of the smartphone, the longer it will have to charge it? For example, 4000 mAh batteries, on average, charge in 3 hours. Charging process can speed up special adapter Quick Charge, with which the charge of half the battery capacity can be gained in 30-40 minutes. But such adapters are rarely included in the delivery of the smartphone - they have to buy them separately, and not all smartphones support "fast charging".

Price: from ~ 400 USD.

Technology: Dual SIM (Dual Active).

SIM format: Nano-SIM.

Huawei P9 is the first smartphone jointly designed with the famous LEICA brand. This flagship, whose chip has become a double 12 megapixel camera: Huawei P9 mission - reboot the photography on the smartphone. And also, add diversion to the world of Dual Stand-by two-moon, because One of the "nine" configurations supports both SIM cards that for smartphones of this class is rather an exception than the rule.

Price: from ~ 450 USD.
