Best Dual SIM Smartphones

Whether you’re looking to invest in a new personal phone, or are hoping to marry your business and work lines into one, powerful device, these top 12 best dual SIM smartphones are sure to fit the bill. Keep reading to find out our top recommendations for the best dual SIM smartphones:

1. Samsung Galaxy S20 5G

Samsung has long been known as one of the world’s best Smartphone manufacturers. Taking the top spot in terms of sales, their popular “S” line-up has been making headlines since it was first released more than 10 years ago. The Samsung Galaxy S20 5G is no exception to the quality and groundbreaking features that this brand has built its name on.

Packing a 6.2” Quad HD+ Dynamic AMOLED 2X Infinity-O Display at 3200×1440 and with a 120hz refresh rate, this phone has one of the world’s leading displays. This monster display is powered by an Adreno 650 mobile GPU, alongside a beefy Octa-core processor that was designed by Samsung themselves. This phone has 128GB of internal storage, 8GB of RAM, and you can even add a microSDXC card if you don’t need the space for a second sim card.

As for features, like most of the “S” line, this phone comes with rapid wireless charging built-in. The front-facing camera has a beefy 10MP sensor, with the lens being hidden in a cut-out in the main screen. The main camera is a triple-sensor array, including a 12MP wide and ultra-wide-angle lens, and a 48MP telephoto lens. Unlike other phones on the market, this device is available in a wide range of colors that look excellent.

One of the weaker points of Samsung devices has always been their operating system. Running Android 10 with Samsung’s own OneUI over the top, this has improved greatly over the years, and most people wouldn’t consider this a weak point for the phone. Having expandable storage is also great, but many users will struggle to wave goodbye to the dual-SIM functionality to be able to use it.

2. Apple iPhone 11 Pro Max

Apple was the first company in the world to reach a market value of $1 trillion, and this is largely thanks to the success of its iPhone lineup. Once viewed as the expensive option to many, iPhones are more competitively priced than ever before, often making them the same price as other flagship devices.

The iPhone 11 Pro Max is Apple’s most recent flagship device. With a 6.5 inch Super Retina XDR OLED display alongside a Hexa-core processor and GPU that Apple designed for themselves. You can choose to have the phone in 64GB, 256GB, or 512GB, but each version comes with 4GB of RAM. These phones use NVMe storage, making it some of the fastest on the market.

The 11 Pro Max comes with a triple rear camera array, including 3 12MP sensors with a wide, ultra-wide, and telephoto lens, and a front-facing selfie camera that is also 12MP. The true power behind these cameras comes in the form of Apple’s image processing software. Well-known as some of the best in the world, you simply can’t find it on other phones.

The biggest downside that comes with Apple devices will be a benefit to those that already own a Mac. There is a tight eco-system surrounding these products, with apple working extremely hard to push people towards using their devices for everything. iTunes has always run incredibly poorly on Windows machines, for example, and this can be a major deal-breaker for a lot of smartphone users.

3. ASUS ROG Phone 2 (ZS660KL) Smartphone

Asus is probably best known for their PC components than their smartphones. This brand has been breaking into the phone market for years, though, with their ROG (Republic of Gamers) phones being marketing towards those who love mobile gaming. This PC-building heritage can be seen in their modern smartphones.

The ROG Phone 2 comes with a Qualcomm SM8150 Snapdragon 855+ and an Adreno 640 to power the games you want to play. This phone is available in 128GB 8GB RAM, 256GB 12GB RAM, 512GB 12GB RAM, and 1TB 12GB RAM storage configurations, giving users loads of choice and making it easy to change the storage size in the phone you want to use. With a pair of DTS:X stereo speakers, few phones are able to provide the audio experience that comes with this device.

This Asus phone has a dual-rear camera, with 12MP ultra-wide and 48MP wide lens, along with a 24MP selfie camera. Many of the main features on this phone are game-oriented. Like the controllers you’d get with a games console, this phone has shoulder buttons that can be used as extra inputs for games. Its USB charging port is located on its side to enable better landscape use, while the port itself has been redesigned to allow attachments to be added to the phone.

These attachments include game controllers, additional cooling fans, and even an extra screen that can be used with certain games. Of course, all of these features sound nice, but you have to spend a small fortune in addition to the phone if you want them. For many people, the availability of cheap aftermarket attachments for other phones will make this feature unimportant.

While this entry is impressive, Asus has a long way to go before they are able to dominate the phone market. Like many of their products, it’s easy to tell that this device has been designed for gamers based on its appearance, and this isn’t very good for professionals that would like to try it out. Alongside this, some versions come without any warranty whatsoever.

4. OnePlus 8 Pro Ultramarine

Child company of cell phone giant Oppo, OnePlus first debuted in the West back in 2014. Starting as a “flagship killer” device, this company has since fallen into step with brands like Samsung and Apple, providing phones with top-specs that are accompanied by top prices. This phone uses OnePlus’ Oxygen Android skin.

This phone matches its competitors in power, with an Octa-core CPU powered by a Qualcomm SM8250 Snapdragon 865 chipset. Alongside this, the phone has an Adreno 650 GPU. You can choose to have this phone with either 128GB of storage and 8GB of RAM or 256GB of storage and 12GB of RAM. This makes this device a powerful contender in the modern market.

This phone has one of the more unique camera setups on today’s shelves. With a regular triple-camera array, including 4MP ultra-wide and wide cameras and an 8MP telephoto camera, you wouldn’t think much of it. This phone also features a 5MP color-filter camera, though. The selfie camera is a single 16MP wide-angle lens. Like many modern smartphones, this device comes with wireless charging.

The OnePlus 8 Pro has met quite a bit of controversy since its release. The Color-filter camera was quickly discovered by users, and it was found that certain materials (including some clothing) appeared invisible with this camera. OnePlus has since had to turn this feature off, effectively wasting their customer’s money and preventing them from using their phone properly.

5. Sony Xperia 1 Unlocked

Sony is one of the oldest players in the smartphone market, has been making phones when the original iPhone hit the market. Unlike other companies, though, Sony avoids many of the market trends seen amongst devices, choosing to go down their own route. This has resulted in a range of phones that are excellent for content production and consumption, with great cameras, screens, and no annoying notches or cutouts to get in the way of it all.

While they may not follow many of the features used by other manufacturers, the Xperia 1 can easily compete when performance is concerned. With an Octa-core CPU and Adreno 640 GPU, 64GB or 128GB of storage, and 6GB of RAM, this phone is just as powerful as many of the other phones you’ll find on the market.

Camera technology has long been one of Sony’s strong suits, with their Alpha range of mirrorless cameras being regarded as some of the best in the world. This heritage has spread over to their smartphones, with a triple camera setup on the rear, and a single 8MP camera on the front of the device. These phones have faster autofocus than many other devices; a great feature for those that like to take photos of sports or wildlife.

While their no-nonsense approach appeals to some users, many phone enthusiasts are put off by the form of this device. Rather than using notches or button-hole cameras, the Xperia 1 still has large bezels at the top and bottom of the display. The screen is 4k and HDR10 compatible, and this may tip the balance for some users.

6. OnePlus 7T PRO HD1910

Going back to OnePlus, it’s time to take a look at one of their slightly older phones. While the OnePlus 7T Pro was launched over a year ago, this device is still a hot contender for many shoppers. Like the OnePlus 8, this phone came after OnePlus’ transition from making budget phones to luxury ones.

With an Octa-core CPU powered by a Qualcomm SM8150 Snapdragon 855+ chipset, users won’t notice the age of this device when it comes to performance. The Adreno 640 GPU is on par with many modern devices and is even overclocked to squeeze more power out of it. The device only comes with 256GB of memory, but you can choose between 8GB and 12GB of RAM.

The selfie camera is one of the show-stopping features on this phone. Rather than notches or holes, OnePlus used a mechanism to raise the selfie camera from the body of the device, leaving the screen almost entirely bezel-free. This camera is 16MP, while the array on the back features a 48MP, 16MP, and 8MP camera, giving you access to wide and telephoto options.

The biggest downside to a phone like this is its age. While this doesn’t mean that it will lack any performance shortcomings, some users will be disappointed when support for the device stops. Alongside this, the flashy front camera may look cool, but mechanisms like this are notoriously unreliable and incredibly expensive to replace.

7. Samsung Galaxy Note 10+ N975F/DS

Samsung has long had more than one range of phones, with their Note series being aimed at the “phablet” market. With a 4K 6.8 inch AMOLED display, many users are blown away by the screens on phones like this. Alongside the screen, though, this phone packs a huge range of features that users will struggle to ignore when they are shopping for their next phone.

The Samsung Galaxy Note 10+ is extremely powerful, with an Octa-core CPU that is powered by a Qualcomm SM8150 Snapdragon 855 chipset. It has an Adreno 640 GPU, 256GB of storage, and 8GB of RAM, making this phone capable of running just about any app or game you can throw at it.

The rear camera array on the Note 10+ includes 2 12MP cameras and a 16MP camera, giving you the full range of focal lengths. The front camera is a 10MP wide-angle option, making it perfect for professional video calls. A blast from the past for many, this phone comes with its own digital stylus. This can be used for drawing, writing, or even controlling the phone, making those who are less tech-savvy feel comfortable with the phone. When paired with a cell phone booster the Note10+ makes for a great all-around platform for remote locations.

It’s hard to think of the downsides that come with a phone like this, though many will see its biggest selling point as a negative; the size. 6.8-inches is a massive screen, making it hard for those with smaller hands to handle the device, let alone use it. Alongside this, the stylus that comes with the phone is easy to lose and expensive to replace.

8. LG G8X ThinQ

The LG G8X is possibly the strangest phone on this list. Following the recent trend of giving phones more screen real estate, this device comes with a removable second screen that can be used for gaming, productivity, and a huge range of other tasks. This enables you to make use of a huge amount of screen without having to compromise on portability.

While many phones with similar features tend to lack the performance of more expensive devices, the G8X has a powerful Octa-core CPU and Qualcomm SM8150 Snapdragon 855 chipset, along with an Adreno 640 GPU. The phone comes with 128GB of internal storage and 6GB of RAM, but you can also add your own microSDXC card if you don’t mind sacrificing one of your SIM slots.

Despite the opportunity to add more camera hardware to the dual-screen case that comes with this device, LG opted to stick with the cameras found on the phone itself. This includes a dual 12MP and 13MP rear array, along with a single 32MP selfie camera. This camera balance shows that this phone is designed more for video calls than taking stunning photos, though this is unlikely to be an issue for many users.

Having a feature like dual-screens on a modern phone is great for a lot of users, but it can end up being a bit of a gimmick for others. Without adding additional cooling, cameras, or other features that smartphone users love, this attempt from LG is a good one but could do with some improvement to make it more valuable to many users.

9. Realme X2 Pro

The Realme X2 Pro may share its name with the recent Oppo line, but this doesn’t mean that these phones are the same. The X2 Pro was designed as an affordable phone that packs many of the features found on flagships in a similar fashion to the devices that OnePlus used to produce. This means that users of the X2 Pro will benefit from blazing speeds and excellent cameras, but will suffer when it comes to other common features.

This device is no slouch, with a Qualcomm SM8150 Snapdragon 855+ powered Octa-core CPU and an overclocked Adreno 640 under the hood. The X2 Pro comes with the option for 64GB of storage and 6GB of RAM, 128GB of storage and 8GB of RAM, 256GB of storage and 8GB of RAM, or 256GB of storage and 12GB of RAM, though it’s worth keeping in mind that the low capacity option has slower storage, too.

It has a quad-camera array, with the standard wide, ultra-wide, and telephoto lenses (64MP, 8MP, 13MP), along with a 2MP camera that is designed to capture depth (and beautiful bokeh). The phone has a single 16MP camera on the front for selfies. This set of cameras will give photographers a unique experience that can’t be found on other phones.

Being a brand that almost no one has heard of presents challenges for a phone like this. Realme has worked extremely hard to create a phone that looks and feels great, but it can be very hard to find accessories like cases for this device. This will change over time but is a consideration any shopper should keep in mind.

10. Nokia 7.2

It’s impossible to ignore it when Nokia releases a new phone. Having risen, fallen, and risen again over the last decade or so, this company has had to fight for its current position in the market. Nokia’s modern phones are known for being hit and miss, though the 7.2 looks far more promising.

With a Qualcomm SDM660 Snapdragon 660 powering an Octa-core CPU and an Adreno 512, this phone doesn’t have quite the same punch as other flagships. You can choose between 64GB of storage and 4GB of RAM or 64GB/128GB of storage and 6GB of RAM, but the phone also comes with a dedicated microSDXC slot that doesn’t force you to sacrifice any other features to use.

As usual, the camera is the main selling point on this Nokia phone. The triple-camera array includes a huge 48MP wide sensor and a smaller 8MP ultra-wide sensor, along with a 5MP camera that is used to generate depth in photos. The lenses themselves are made by Zeiss; one of the most popular optics manufacturers in the world.

Nokia has worked hard for decades to produce phones that meet their tight standards. Unfortunately, though, they’ve been working to provide features that many users simply don’t need in modern times. A 48MP camera, for example, sounds great on paper, but it becomes clear that this isn’t going to be very impactful when you realize that many of the world’s best mirrorless cameras sitting in the 20MP to 30MP range.

11. Google Pixel 4a

Google has been producing its Pixel line for many years, having bought companies like Motorola and LG’s phone division. These phones are designed to set the standard for other Android devices, with many manufacturers following suit when Google decides to include weird and wonderful features. Google was one of the first Android phone makers to ditch headphone jacks, for example.

The specs that come with the Pixel 4A are modest but capable, with a Qualcomm SDM730 Snapdragon 730G powering an Octa-core CPU and an Adreno 618 GPU to go alongside it. There is no option for additional storage, and the phone is only available with 128GB of storage and 6GB of RAM. This storage is using the slower UFS 2.1 standard.

Unlike many other smartphones, the Pixel 4A only has a single rear camera. A 12.2MP wide-angle sensor should be more than enough for most people, but it does limit your ability to zoom in and out or create unique shots. The selfie option on this phone is an 8MP wide-angle camera. There is no option for wireless charging available, but this device does come with an Always-On Display.

The biggest issue with the Google Pixel 4A is only visible when you compare it with the other phones on this list; power. Up against the likes of the iPhone 11 Pro Max or the OnePlus 8 Pro, this offering from Google simply doesn’t stand a chance. Comparing the prices of these devices can give you a good idea as to why this is.

12. Moto G8+ Plus

Motorola has been Google’s budget wing ever since they bought the company almost a decade ago. This means that many of the phones that have the Moto name aren’t comparable to the more expensive devices on the market, and it’s well worth doing your research before choosing one of these phones. That said, the Moto G8+ offers incredible value when compared to other phones within its bracket.

When it comes to specs, this phone will probably surprise you. Despite the budget category it falls into, this phone comes with an Octa-core CPU that is powered by the venerable Qualcomm SDM665 Snapdragon 665. This is coupled with an Adreno 610 GPU to provide smooth response times and excellent price-to-performance value. The phone comes with 64GB of storage and 4GB of RAM as standard, but you can also add a microSDXC card if you don’t mind sacrificing a SIM slot.

At the back of the device, you will find a triple camera array with a 48MP wide lens and a 12MP ultra-wide lens, along with a small 5MP sensor that is used for depth. The G8+ comes with a respectable 25MP front selfie camera, making the device ideal for video calls. This device lacks many of the features found on pricier phones, but it makes up for it where it matters.

Any budget device is going to come with some downsides, and it’s impossible to ignore the construction of a phone like this. Made with a fully-plastic case and glass screen, this device won’t feel anywhere near as premium as the other options in this review. Alongside this, power users will probably want a phone with a little more meat to it, with certain tasks being slow and hard to perform on a phone like this.
