While most users can get by with a single SIM handset, there’s something to be said about the flexibility that a dual-SIM device can offer. A dual-SIM setup lets you have two different phone numbers while also using one SIM for data and another for calls and texts. Here are our picks for the best dual-SIM Android phones you can buy, but make sure you don’t accidentally grab a single SIM version instead!

The best dual-SIM Android phones:
Editor’s note: We will be updating this list as more dual-SIM devices hit the market.
1. Samsung Galaxy S21 series
David Imel / Android Authority
It’s a new year, and that means a new slate of powerful Samsung Galaxy devices. The Galaxy S21 family currently includes three devices, each of which supports dual-SIM functionality. It remains to be seen whether all Galaxy S21 devices are dual-SIM enabled or only devices outside the US.

All three Galaxy S21 models offer 120Hz AMOLED displays, Snapdragon 888 (or Exynos 2100) processors, 8GB or 12GB of RAM, and up to 512GB of storage. The premium S20 Ultra even offers 16GB of RAM, although that’s certainly overkill for anything you’d want to do on the phone. Samsung’s new Galaxy S21 family isn’t cheap by any means, but it’s more approachable than in previous years. The only downside is global editions feature the slightly less powerful Exynos 2100. Also, while you’re here, Samsung’s S10 line of smartphones was all dual-SIM in the same global-unlocked configuration only.

Eric Zeman / Android Authority
Samsung’s Galaxy Note smartphones have always been among the most ultra-premium phones on the market, so it should come as no surprise that the latest Galaxy Note 20 Ultra is one of the best phones available full stop. Just note only the Ultra has dual-SIM in a hybrid SIM, not the vanilla model.
Next: Samsung Galaxy Note 20 vs Galaxy S20 series
If money is no object, the Galaxy Note 20 Ultra has it all. It sports a huge 6.9-inch AMOLED display with a 120Hz refresh rate and 12GB of RAM. The cameras on this model are also top of the line, with a triple camera setup led by a wide-angle 108MP sensor. The Ultra has the latest Snapdragon 865 Plus processors (or Exynos 990, but you should avoid this model if possible) and, of course, the ever-popular S Pen accessory. You also get all of the standard premium trappings like an IP68 rating and wireless charging.

3. OnePlus 9 and 9 Pro
Robert Triggs / Android Authority
The latest OnePlus flagships are here, and we recommend both if you want dual-SIM capabilities. Both devices pack plenty of the same features, though the OnePlus 9 Pro has finally ticked into the true flagship price range.
They hit many flagship highlights — high-end processing packages, impressive 120Hz displays, beautiful designs, solid build quality, and excellent battery life. Even better, both phones now come with speedy wireless charging straight out of the box. You still won’t find an IP68 rating on the unlocked OnePlus 9, though the T-Mobile version comes with one, suggesting that both models are waterproof.
Here: OnePlus 9, OnePlus 9 Pro, and OnePlus 9R buyer’s guide
OnePlus’ latest version of fast charging lets you fully charge its large battery in just 39 minutes and could provide a day’s worth of use with just a 15-minute charge. A full battery in less than 40 minutes is no small feat either; both phones pack 4,500mAh cells.

4. Xiaomi MI Mi 11
Eric Zeman / Android Authority
The first dual-SIM device on our list is also the winner of the Snapdragon 888 race. Xiaomi MI’s Mi 11 launched first in China, packing Qualcomm’s latest chip and a massive 6.81-inch display. You can also choose from either 8GB or 12GB of RAM to power your new device.
Xiaomi MI chose a triple rear camera setup to lead the way on its Mi 11, highlighted by a 108MP main shooter. You’ll have a macro sensor and an ultra-wide lens to work with as well. In addition to your dual-SIM flexibility, you can also take advantage of all-day power with the solid 4,600mAh battery.
If there’s one potential drawback with the Mi 11, it has to be the software. You might like Xiaomi MI’s MIUI skin, but it often leaves a bit to be desired. On the bright side, you can always change the look and feel with a launcher.

5. Sony Xperia 1 III and Xperia 5 III
Robert Triggs / Android Authority
The latest Sony flagships have arrived, or at least they’re available for preorder. That means you can finally look forward to bringing the new and wildly expensive Xperia 1 III into your home. If you want a slightly more affordable experience, the Xperia 5 III is just around the corner, too.
Sony’s slightly more affordable flagship, the Xperia 5 III, packs a Snapdragon 888 Plus chip under the hood along with 8GB of RAM. However, if you opt for the Xperia 1 III, you can jump to 12GB instead. You’ll find three 12MP cameras at the back of both the Xperia 1 III and 5 III, as well as a ToF sensor on the Xperia 1 III that should help with portrait mode images. The SIM tray accommodates a dual-SIM offering hybrid, dual standby.

Like most other Xperia phones, the weirdly named pair features side-mounted fingerprint scanners. They also come with 21:9 displays that make the phones quite lanky. You also get wireless charging on the Xperia 1 III, an IP68 rating, and even a headphone jack. All these things combined make it one of the best dual-SIM phones you can get.

6. Oppo Reno 6 Pro 5G
Dhruv Bhutani / Android Authority
The Oppo Reno 6 Pro 5G is a beast of a dual-SIM phone. It finally ditches the glossy finish and packs plenty of solid 2021 midrange features, including a MediaTek Dimensity 1200 processor, a 90Hz AMOLED screen, up to 12GB of RAM, and a 4,500mAh battery with blazing-fast 65W charging. And dual sim dual standby, even with 5G.

The Reno 6 Pro’s camera credentials are nearly unchanged from the Reno 5 Pro, delivering a 64MP camera backed by an 8MP unit and a pair of 2MP lenses. Just don’t expect 8K video recording, though 4K video should be fine for most users.
This mid-range powerhouse doesn’t come with an IP rating or any mention of splash resistance, but it’s built from Gorilla Glass 5 and can handle two SIM cards at once. It’s a big device sporting a 6.55-inch display.

7. Hãng Asus Zenfone 8 and 8 Flip
Eric Zeman / Android Authority
The Hãng Asus Zenfone 8 is a powerful little flagship with premium specs that can handle two SIM cards at once. The Zenfone 8 Flip carries on the successes of one of the best all-around camera phones in the Hãng Asus Zenfone 7 Pro thanks to its unique camera mechanism, which flips the rear cameras around to point them towards the front. It’s now a 64MP IMX686 main shooter, with an ultra-wide lens as well and 3x telephoto to cap it off.

Both devices pack Qualcomm’s latest Snapdragon 888 chipset and crisp Full HD+ displays, but the spec sheets diverge from there. The Zenfone 8 has just a 5.9-inch Gorilla Glass Victus display, while the 8 Flip goes larger with a 6.67-inch option. However, it swaps down to Gorilla Glass 6 and trades a 120Hz refresh rate for a 90Hz version.
Even the battery size differs between the two, with the Zenfone 8 adding a 4,000mAh cell to its dual-SIM setup while the larger phone opts for a 5,000mAh cell.

8. Hãng Asus ROG Phone 5
Ryan-Thomas Shaw / Android Authority
The Hãng Asus ROG Phone 5 is a worthy successor to last year’s ROG Phone 3. It’s the current gaming-themed champion of Android smartphones with the highest-end specs, plus some extras. It has a Qualcomm Snapdragon 888 processor, a 6.78-inch display with a 144Hz refresh rate screen, up to 512GB of storage, and up to 18GB of RAM. The ROG Phone 5 also has one of the largest batteries on the market at a whopping 6,000mAh, plus an impressive 64MP IMX686 main rear camera. There are some great stereo front-firing speakers on the phone and a Quad DAC-powered headphone port. Like its predecessors, it has two capacitive Air Triggers for gaming along with dual-SIM / dual-standby support.

This phone has two variants, both of which have small rear screens in the back. The Hãng Asus ROG 5 Pro has a color PMOLED display on the back, while the ROG Phone 5 Ultimate model has a monochromatic version of the same small display. Both are used to show off animated icons and GIFs, but that’s it. The Pro and Ultimate models also have two touch sensors on the back. You can buy first-party accessories for the phone, including the Kunai 3 left and right gamepad modules that can be mix and matched.

9. Poco F3
C. Scott Brown / Android Authority
The Poco F3 is also known as the Redmi K40 Pro in some markets. It’s a phone with premium hardware, dual-SIM standby, and has the specs to match most phones in this list, but at a lower cost. It drops wireless charging and IP rating to save on price, and it has a great package overall.
The battery is said to go from zero to 100 percent in 52 minutes.
This Snapdragon 870 phone sports a 6.67-inch Full HD+ display, up to 8GB of RAM, and a 4,520mAh battery with 33-watt charging. The company claims you can get the battery from zero to 100% in 52 minutes.
The F3 also moved to the punch hole selfie lens, three rear cameras, and ditched the headphone jack. Overall, the hardware makes the Poco F3 one of the best dual-SIM phones to get, even if the software lets it down a bit.

10. Oppo Find X3 Pro
Adam Molina / Android Authority
This is the best Oppo phone you can currently get, and yes, it can handle two SIMs at once. The Find X3 Pro is an impressive early 2021 device with a Snapdragon 888 chipset, IP68 rating, and futuristic styling that would look right at home in a Star Wars flick.
Oppo’s Find X3 Pro blends high-end speed with Star Wars style.
Oppo’s camera bump is one of the most unique we’ve seen in a while, and it seems to melt into the device itself. It stars a pair of 50MP shooters along with a 13MP telephoto lens and a 3MP macro to give you some extra flexibility. You’ll have some problems with fingerprints due to the high-gloss finish, so be ready to clean often.

These are our picks for the best dual-SIM options Android has to offer at the moment. We’ll add more as new dual-SIM phones come to market.
We do get one frequently asked question that’s worth addressing here, too. Many people are looking for dual-SIM phones, but some are looking for Dual Active SIM phones instead of Dual Standby. Dual Standby is much, much more common, and every phone listed here is that type.
Dual Active SIM phones are almost completely extinct because carriers support new phone options to conduct multiple connections. The move has been made over to VoLTE by most carriers in most locations. That allows you to two calls at once over data, which essentially was a key reason for having older Dual Active options, where it was more necessary to establish the connections.
