The Snapdragon 855, 845, 820, 821, and 835 chips are the latest and greatest processors running the best Android phones today, with the latest Samsung galaxy s10 already running the 855 chip.  The particular spec you should be excited about is the LTE Dual SIM Dual Standby.  What that means is phones with the Snapdragon 820, 821, and 835 processors have dual or duo SIM capability.  And the best part is both SIMs are capable of running 4G LTE (i.e., running 4G one SIM and 3G on the other SIM).  You would think this is no big deal, but the majority of the old model phones can only run 4G/2G or 3G/2G.  This is important because 2G is getting phased out all over the world very soon.

Dual-SIM Active vs. Dual or Duo SIM Standby

Dual or Duo Sim Dual Standby phones require the user to designate which SIM you like to receive calls.  You also cannot surf the web with one SIM and receive a call on the other SIM.  As the name suggests, one is always on standby, but you would not be able to use both at the same time.

Dual SIM Dual Active phones, on the other hand, are much more useful.  You can be browsing the net on your phone with one SIM and still receive an incoming call from the other SIM card.  Unfortunately, there are very few dual active phones currently available on the market.

1. Moto G6

The Moto G line of affordable smartphones has effectively convinced the Western world that one doesn’t have to pay hundreds of dollars to get a decent smartphone for daily use. They were the first to nail down the specifications and save money on things that matter the least. To this day, the Moto G is the most recommended budget smartphone on the market, and it’s also an excellent choice for an affordable dual SIM card Android phone.

What makes this compact 5.7” device with HD screen so great in the budget level combined with IPX7 waterproof design and a rear-facing camera that produces better pictures than some models that cost twice or three times as much. It has a resolution of 12-megapixel, as well as a second 5-megapixel shooter to go with it. The included dual-LED flash ensures that low-light situations don’t pose any problem.

A snappy performance is provided by the Snapdragon 450 CPU with 3 GB of RAM, depending on which model you go with. The cheaper option has only 16 GB of built-in storage.

The only flaw of this otherwise stellar dual SIM smartphone is its thickness. Compared with other, slimmer devices, the phone feels chunky and, at times, let’s you know that you have it in your pocket.

  • IPX7 waterproof design
  • Very affordable
  • High-quality rear camera
  • Chunky design

2. Samsung Galaxy S10

Galaxy devices are always expected to represent the very best that Android has to offer. That’s partly due to their high price, but, more importantly, because of their commitment to excellence and innovation. The Samsung Galaxy S10 had a difficult mission to accomplish as Samsung already released their latest Samsung Galaxy S20 and Samsung Galaxy Note 20 series. Samsung had to convince customers that there’s still plenty of reasons why go with an established manufacturer over the competition from China.

The South Korean smartphone manufacturer has wisely stuck with what they are known for and only made it better. We are talking, of course, about the exceptional rear- and front-facing cameras and the gorgeous design. The Galaxy S10 costs around $900 for the 128GB variant and it is still a great device for this price point. It may still run on Android 9 0 out of the box but you can definitely update it to the last Android 10 version.

The main camera is actually a triple camera lens setup, featuring two 12 megapixel sensors, as well as a 16-megapixel unit. It features phase detection autofocus with optical image stabilization. The autofocus mechanism is so fast that you never miss a chance to take a great picture only because you have to wait for the image to come into focus. The camera also records 4K video at 30 frames per second. The front-facing camera has a resolution of 8 MP, and its bright sensor copes very well with low-light conditions. This is one of the best camera phones that you can still get in the market.

Aside from the triple lens excellent camera setup, this S 10 Samsung Galaxy device also comes with a great display. Because of the 6.1-inch display with an incredible 550 PPI pixel density screen resolution, the galaxy s10 has retained a compact form-factor that’s very easy to use with just one hand. The glossy back adds a touch of luxury, but it also does attract fingerprints like a magnet. But that can be forgiven because it hides a massive 3400 mAh battery that lasts all day long.

  • Bezel-less “infinity display” phone
  • Flawless screen
  • Best camera for Android
  • Premium design
  • Long battery life

3. Xiaomi Pocophone F1

Coming up close to last on our top 10 Android Dual-SIM phones, but certainly not the least, we’re looking at Xiaomi’s very own Pocophone F1, the dual-SIM Android phone that everyone needs. One of the common things among top tier phones with Dual SIM support is just how pricey your flagship phones cost. Xiaomi tries to change that here.

If you’re looking for a cheap Android flagship with top tier hardware and dual-SIM support, look no further than the Pocophone F1. It sits at budget level pricing, but you really cannot go wrong with it. Despite its low price, the Pocophone X! still sports the latest flagship hardware out there. This phone stays snappy, as it’s equipped with a Snapdragon 845 processor, as well as 6 GB of memory and 64 GB of expandable storage in the base model.

For the price of the Pocophone F1, the battery might surprise you as well — it’s got a 4,000mAh unit packed inside. That keeps things running exceptionally smoothly. The only thing that this display doesn’t have is NFC support, and it does have a reasonably standard or normal IPS LCD display with a camera notch, rounded corners, and small borders. But for just a couple hundred, where can you go wrong? Especially with dual-SIM support in tow.

4. OnePlus 6T

The founder of OnePlus, Carl Pei, said that people have very, very high expectations for the OnePlus 6T. No wonder they do. After all, the first OnePlus was such a huge success that the unknown Chinese smartphone manufacturer has overnight become one of the best-known brands in the industry.

The third smartphone from the influential company follows the same principle as the previous two. The idea is to release a flagship device for a mid-range price. In this case, we get a Snapdragon 845 processor coupled with 8 GB of RAM — up to 10GB with the McLaren edition — and Adreno 640 GPU. With such powerful hardware, it’s almost impossible to push the smartphone to its limits.

Things look equally impressive even as far as the rest of the OnePlus 6T is concerned. The dual 16-megapixel and 20-megapixel unit, and then the 16MP front-facing camera, can both record full HD video footage and take great-looking pictures in all light conditions. You can then view your creations on the 6.41-inch Full HD+ Optic AMOLED display with 402 PPI pixel density.

This OnePlus smartphone actually comes with double SIM support as well, allowing you to swap networks as needed. It also has an in-display fingerprint scanner or an in-display fingerprint sensor which is quite usable.

  • Powerful hardware
  • Premium build quality
  • Relatively affordable
  • 8 GB RAM
  • Lack of microSD card slot

5. Huawei Mate 20

The Huawei Mate 20 was initially supposed to be available only in China, a country where extra-large smartphones are the norm. Fortunately for the rest of the world, Huawei has decided on a global debut, and we are glad they did.

The main selling point of this remarkable double SIM smartphone is the stunning 6.53” screen with an excellent screen-to-body ratio, making the bezel nearly invisible. The custom launcher that ships with the smartphone effectively take advantage of the massive space by making essential features available either at a glance or with just a few taps. The only real downside is that the launcher can sometimes get a bit laggy, but that’s something that Huawei could quickly fix with a future update or two.

Despite its thin profile, the Mate 20 features a large, 4000 mAh battery with fast battery charging. You can expect up to 15 hours of battery life with regular use, and it takes just a few minutes to charge the battery beyond 30%. And this phone has a headphone jack, not like the upgraded Mate 20 Pro and Huawei P30 Pro. It also supports stereo speakers for a nice and crisp audio output.

Huawei markets this smartphone as a productivity device first and then a lifestyle gadget second, unlike the Huawei P30 Pro. That might explain the somewhat underwhelming performance of the camera. The quality isn’t terrible, but the fantastic sharpness and color saturation of Galaxy devices or even the Moto G is absent.

  • Outstanding battery performance
  • Stylish design
  • Sturdy build quality
  • Fingerprint sensor
  • Problematic software
  • Average camera

6. LG G8 ThinQ

The LG G8 ThinQ is the perfect candidate for a dedicated camera grip, as it comes with not one but two rear cameras, or three, if you choose the right model. There is a more traditional 12-megapixel camera right next to a wide-angle 26-megapixel camera, or you can select two 12-megapixel cameras and a 16-megapixel unit. The provided camera software allows you to switch between them on-the-fly, so you can decide which is more suitable for the particular shot. In general, the wide-angle lens comes in handy in tight spaces and whenever you do landscape photography.

Inside the flagship phone are only the best flagship components. It comes with the Snapdragon 855 CPU with 6 GB RAM, 128GB of internal storage, and Quick Charge 3.0 fast-charging battery technology(battery life usage should not be an issue with the device). To top it all off, LG went with a beautiful 6.1-inch screen with excellent resolution.

  • Wide-angle camera
  • Beautiful screen
  • Great display
  • Uncompromising performance
  • The camera isn’t a massive improvement from the G5
  • Its primary high-end competitors are all running the latest Snapdragon 835 chip
  • Non Removable Battery

7. BLU Vivo One

BLU was founded in 2009 with a vision to bring affordable yet capable devices to masses. The sand-blasted Vivo One, which looks and feels like a high-end device, certainly follows the company’s original vision. Just like the famous Moto G, this is a no-frills smartphone for users who don’t need much to do a lot.

There is no removable cover, but there is a slot that houses two SIM cards or a SIM card and a microSD card. Additionally, there is a 3,000mAh non-removable battery with should provide you a mediocre battery life. The BLU Vivi One uses a MediaTek CPU with a Mali-based GPU, and then there’s also 2 GB of RAM. The resulting user experience is exceptionally smooth, mainly because the Android operating system is nearly in its stock configuration.

Located in the top left corner is the 12 MP camera with an LED flash right next to it. For what it is, the camera takes pretty decent pictures. It performs best when you shoot outside in broad daylight. Indoor or nighttime photography usually results in blurry and/or noisy pictures.

  • Great design
  • Nearly stock Android
  • Inexpensive
  • Decent camera performance
  • Non-removable battery

8. Asus ZenFone Max Pro M2

After the well-received ZenFone 4, Asus is ready to fight for a dominant position in the mid-range category. Their latest model for midrange phones (Zenfone 7 Pro is their actual latest device), the Asus ZenFone Max Pro M2, is undoubtedly a worthy contestant. The luxurious body of this smartphone is made primarily from glass. Unsurprisingly, the surface is a fingerprint magnet, but the upside is a premium look and feel.

For a mid-range smartphone, the ZenFone Max Pro M2 is packed with a pleasing assortment of features and hardware components. There’s a fingerprint reader on the back, laser autofocus system for the 12-megapixel rear-facing camera, a massive 5000mAh battery, and a microSD card slot that can take cards up to 512GB in size.

The Snapdragon 660 with 6GB of RAM provides a stable and speedy performance in addition to good battery life, while the 6.26-inch Full HD display offers an uncompromising multimedia experience. It’s then only the software side of things that will make some fall in love with the phone, and others turn away from it. Asus uses its proprietary ZenUI home screen replacement in conjunction with countless applications and utilities. Those who prefer a more stock experience will have to spend quite a lot of time performing a tedious cleanup or replacing the stock firmware with an after-market solution.

  • Long battery life
  • Bright screen
  • Quality camera
  • Plenty of RAM
  • Bloatware

9. Oppo Find X

The Oppo Find X is the last affordable dual SIM card Android smartphones on this list. Its main strength is the excellent front-facing 25 MP camera that can shoot 1080p video and take great-looking pictures both indoors and outdoors. The rear-facing camera doesn’t lag too much behind, giving you beautiful 16-megapixel sensors able to capture photos in 2K resolution.

The aluminum on the back makes the Find X feel more rigid and expensive. The slightly golden finish elegantly hides all fingerprints and keeps scratches at bay. Similarly, adequate protection against damage can be found even in the front. The 6.42-inch display is covered with the latest Gorilla Glass screen protection technology.

The Oppo Find X ships with Android Oreo, and Oppo’s own with ColorOS custom launcher; this is probably the weakest part of the phone. Just like Apple devices, the launcher doesn’t come with an app drawer so that application management can be quite convoluted. At least, the performance is satisfactory, thanks to the Snapdragon 845 and 8 GB of RAM. You can get it in 128/256GB of storage space, as well.

  • One of the best selfie cameras
  • Affordable
  • Stunning metal body
  • Great ergonomics
  • Software problems with colorOS

Your picture-taking needs will be taken care of by the 12 MP rear-facing camera and the 8 MP self-portrait camera. The dual sim best phones performance is excellent, and the included LED flash helps in bad light conditions.

  1. Asus zenfone 2 is not an option anymore for a dual active sim phone. 2G networks only on Sim 2 is simply no longer available in Canada. Nice phone, but only if you want to use it for 1 sim.

  2. In the US, AT&T no longer have 2G in all areas. I discovered this when my Dual sim phone stopped working in Los Angeles in February 2017. I don’t have a AT&T account, but it affected me because one of my carriers use AT&T when global roaming.

  3. Hello,
    Thanks for the interesting article.
    Would you be able to suggest a dual-SIM phone 4g+4g or at least 4g+3g
    with a separate micro-SD card slot (not shared with 2nd SIM)
    and woeking on EU LTE bands?
    Thanks a lot

  4. The con of the OnePlus 5 (having no micro sd-card slot) is a non arguiment : it has the possibility to insert a SD-card : it uses the second sim slot to do so, as most other dual sim phones nowadays do.
    THE con for me for the OnePlus 5 (and why I don’t buy it) is the lack of IP rating…

  5. I couldn’t agree more with those saying 2G+4G dual active phones are just useless [and a pure marketing-gimmick]? With the advent of “greenfield-4G” (read 4G-only) carriers in developing world and shutdown of 2G services in developed world, isn’t it purely a money-extortion practice on either manufacturers or carriers, or on part of both? Because specially in this day-and-age where doing so isn’t a technical-challenge anymore (even more so in particularly supporting VoLTE™ and VoWiFi™ signals) and to act impartial, the only drawbacks to customers is that normal consumption average of both battery and processor will rise.

    Who’s with me??

  6. You say at beginning
    “phones with the Snapdragon 820, 821 and 835 processors have dual SIM capability. And the best part is both SIMs are capable of running 4G LTE (i.e. running 4G one SIM and 3G on the other SIM).”
    and then I see at least half of the ten recommended phones have a lower version no. processor. So why do you stress how important these cpu’s are ( soon no 2G etc) ?

  7. I’m looking for a dual sim phone but living in Japan you are restricted to not having the 2G network available. Both sims must be able to run on LTE or its useless.

  8. Useless article since you need to take into account the LTE bands in each phone and whether or not the second sim is 2G only or 4G LTE capable. Who cares if the phone is dual sim but the second sim is stuck on 2G.

  9. Thank you for this useful article. I am going with One Plus 3T for sure. You made it easier for me to choose.

    The Galaxy S7 sold in the U.S. is NOT a dual sim phone!

    I purchased one, and was just told by Tech support that this is not true. U.S. sold S7s are NOT dual sim.

  11. Dual sim phones with hybrid sd card slots are useless, whats the point of having two sims if you can not expand your memory? Also having the second sim in 2g is terrible. I hate those phones

  12. Do any of these phones have a 3G card as the 2nd slot (1st slot having 3 or 4G)? I bought the Huawei P8 Lite in 2016, in part based on your recommendation. The problem now is that the 2nd sim is a 2G, and AT&T has discontinued their 2G service. T-Mobile still has it, but it is spotty at best, and will also be going away. Any 3G/4G phones out there? Thanks!
    ETA: I’m in the US, so it has to work on US networks.
