The best dual SIM phones (Updated July 2021)

The best dual SIM phones (Updated July 2021)
What is the best dual SIM phone in 2021? Phones that can maintain two carrier network connections at once have been around for a while, lurking on the outskirts of mass adoption anywhere but in emerging markets, where those are very, very popular. If you want to take advantage of two good carrier plans at once, or use one number for the family and friends and another for work, you need a modern dual SIM phone.

Below we've rounded up best dual SIM phones money can buy right now, for the times when one Subscriber Identity Module just won't cut it. We now also include Android phones and Apple's iPhones that sport eSIM modules, which allow you to switch between providers and can be counted as multi-SIM phones.

Best flagship dual SIM phones


Samsung Galaxy S21, S21+ and S21 Ultra

Samsung Galaxy S21 Ultra
9.1

Samsung Galaxy S21 Ultra


The Good

  • The longest, cleanest zoom on a phone, and most versatile camera set
  • The best battery life in its class
  • Brightest display with the most granular adaptive refresh rate
  • Stylish Contour Cut design and richer variety of colors
  • Unique 12-bit color RAW capture at 108MP
  • S Pen stylus support
  • Next-gen Wi-fi 6E standard support

The Bad

  • Still big and bulky to carry and use, especially with an S Pen case on
  • $1200 gets you just 128GB, no charger, earbuds, or memory card slot
  • The new ultrasonic finger scanner is still comparatively slow
  • Softness in the main camera sample edges

Samsung's latest S-series flagships all support eSIM, come with 5G support, and in some regions have dual SIM also. They're all sporting super-smooth 120Hz displays, pack impressive cameras and the Galaxy S21 Ultra even has S Pen stylus support, which was once limited to the Note series.

The Galaxy S21 phones are not only among the best dual SIM / eSIM phones out there, but arguably among the overall best Android smartphones to pick up right now. If you'd like to learn more about the Galaxy S21 series and their many other features, check out our Galaxy S21 review, Galaxy S21+ review or Galaxy S21 Ultra review.

Samsung Galaxy Note 20 and Note 20 Ultra

Samsung Galaxy Note 20 Ultra
9.3

Samsung Galaxy Note 20 Ultra


The Good

  • Beautiful styling, luxurious feel
  • Super smooth and snappy performance
  • Excellent camera quality for both photos and videos (auto-focus issue is fixed)
  • The biggest improvement to the S Pen so far
  • Outstanding 6.9” AMOLED screen
  • Cool features like Wireless DeX

The Bad

  • $1,300 starting price is a bit too much
  • Gigantic size might be a turn off for some, no smaller model available
  • Battery life is just okay, 120Hz takes a toll
  • No headphones in the box

Like the S series, Samsung's Note series support either eSIM or dual SIM depending on your country and carrier. So either variants can easily be used as dual SIM phones. What makes the Note series special is their dedicated stylus and productivity features. Both the Note 20 and Note 20 Ultra come with a slot-in S Pen stylus, meaning it's easily stored inside the phone itself and can be quickly popped out when needed.

Android power users will also be happy to know that the Note series also come with DeX support, a feature that can change your phone's interface to one that resembles a computer, with multi windows and a taskbar, as soon as you connect the phone to a larger screen. The Note 20 Ultra has a smooth 120Hz display like the S series, although the Note 20 only refreshes at the more standard 60Hz.

If you're interested in getting to know these two phones better, feel free to check out our Galaxy Note 20 review and Galaxy Note 20 Ultra review, where we've shared our experiences using these phones and have camera samples, benchmarks and more to show you.

Apple iPhone 12 Pro Max


The Good

  • Largest, toughest display on an iPhone
  • The best camera set on an iPhone
  • Double the base storage of its predecessor
  • Futureproof 5G support with bands record
  • Best water-resistance on a general purpose phone

The Bad

  • Static 60Hz display refresh on a $1099 phone
  • Blocky and heavy compared to its peers
  • Expensive $599 body repair if you crack the rear
  • No power adapter in the box, slow charging

While we're waiting for the iPhone 13 to be announced, we can recommend Apple's current iPhone 12 series, as all four phones have dual SIM support with nano-SIM and eSIM. You can also use 5G with dual SIM on all of them easily. Of course, as with the other eSIM choices on this list, you'll need a carrier that actually supports eSIM, so make sure to check with your chosen one.

In the US, the carriers that support eSIM are AT&T, T-Mobile USA, Truphone, Ubigi, Verizon Wireless and Visible. In the UK those are EE, O2, Truphone and Ubigi. If you're in another country, you can check for eSIM support for your iPhone at Apple's eSIM service page.

And as for the iPhone 12 series, if you'd like to learn more about a particular phone in the bunch, please see our iPhone 12 review, iPhone 12 mini review, iPhone 12 Pro review or iPhone 12 Pro Max review.

The Bad

  • Grossly overpriced
  • Overheats easily
  • Battery life is just average
  • Photo and video quality is disappointing

Sony's flagship Xperia 1 III supports dual Nano SIM cards. We also found it to be quite the enthusiast dream phone, with its 4K display, expandable storage, manual camera controls, headphone jack – all features we don't often see in 2021 flagships.

However, even though this beast of a smartphone is definitely one of the best dual SIM Android phones to get right now, it's also very expensive. Thus, you may want to check out our Sony Xperia 1 III review to make sure this is the right phone for you, and what it delivers is satisfactory, before committing to purchasing it.

The Asus ROG Phone 5 and its flagship variant – the ROG Phone 5 Ultimate are some of the most powerful enthusiast Android phones to pick up in 2021. Add to that – some of the best dual SIM phones too, as both have slots for two SIM cards.

In our ROG Phone 5 and ROG Phone 5 Ultimate reviews, we were particularly impressed with their speakers, which are possibly the best on an Android phone to date. On top of that, the ROG Phone 5 series deliver great performance, have super-smooth OLED displays, long battery life, and of course, as they're gaming-oriented – plenty of gamer features. Those include a stylish design with a light-up logo on the back, AirTriggers and support for gaming accessories, such as gamepads.

In our Google Pixel 5 review we found Google's flagship to be very light and clean in design, with strong battery life, a bright display and of course – excellent camera performance. And since this is a Google phone, you can expect to be one of the first to get the latest Android updates, such as the upcoming Android 12

During our Asus Zenfone 8 review, we were happy to point out that it has a headphone jack, fantastic performance and a very comfortable design. It's also water and dust resistant, plus its dual cameras aren't too shabby. Considering its price, this is a well-rounded flagship with dual SIM support.

The Bad

  • Camera was a bit of a letdown

And as we pointed out in our OnePlus 9 review, its camera performance should please most users.
