Best Dual-SIM Phone 2025: One Phone, Two SIM Cards

The Galaxy S25 Ultra is the best phone you can buy, and the good news is that it supports two SIM cards in almost all markets. The bad news? That doesn’t include the US, which allows for two eSIM profiles alongside one physical SIM slot.

However, that doesn’t stop the S25 Ultra from being a stellar phone. There are now even fewer weaknesses than before, with even more processing power, small but noticeable camera improvements and a new anti-reflective screen that puts the 6.9-inch, 120Hz OLED panel in a league of its own. The newly rounded corners make it easier to hold.

You also get the best software experience we’ve ever seen on a Samsung phone (and maybe an Android phone full stop), with an extensive suite of genuinely useful AI features and class-leading seven-year update support.

However, it’s by no means perfect. It’s a shame to see the built-in S Pen downgraded to be without Bluetooth, while such a heavy, bulky phone won’t be for everyone. It’s also still very expensive.

But if you want the best of the best when it comes to smartphones right now, the S25 Ultra is the device to get.

The OnePlus 13 takes what made the OnePlus 12 so great and makes it even better. This is the best phone OnePlus has ever made, and up there with the finest around right now. It also supports dual physical SIM cards in all markets where it’s available – including the UK and US.

What makes it so good? It’s a brilliant combination of top-class hardware, slick software and extensive support, meaning the phone could be your main phone for many years to come.

Highlights include the stellar Snapdragon 8 Elite performance, a gorgeous 6.82-inch OLED screen and incredible battery life with 100W charging support. Those factors alone are enough to make it worth considering.

But the OnePlus 13 is equally impressive on the software side, with Oxygen OS one of the best Android skins around and lots of useful AI features. Four years of OS updates and six years of security updates isn’t class-leading, but plenty good enough for most people.

With all that in mind, and a price tag that significantly undercuts many rivals, why wouldn’t you buy it? Unfortunately, while good enough for most people, the cameras are a clear step down from the best around, which will be a dealbreaker for many.

If you can look beyond that and the fact a case is required for MagSafe-style magnetic charging accessories, the OnePlus 13 will serve you very well.

If photography is your top priority, there’s no better phone than the Xiaomi 15 Ultra right now. When it comes to stills, the handset is in a league of its own.

Alongside a trio of 50Mp lenses (main, ultrawide and 3x telephoto), you also now get a 200Mp periscope with 4.3x optical zoom. That enables some of the best zoom shots you’ll find on any phone, though the loss of variable aperture on main lens makes it slightly less flexible when the subject is closer.

Still, with the optional Photography Kit accessory, it comes closer to replacing a DSLR than any other handset. A very capable 32Mp selfie camera is the icing on the cake.

However, you won’t be taking photos all the time, so it’s good to know that the Xiaomi 15 Ultra boasts top-tier performance, a gorgeous display and strong battery life (plus 90W fast charging), all with a durable yet chunky design.

Its main drawback is on the software side, where Xiaomi’s HyperOS 2 skin doesn’t feel particularly intuitive and AI features aren’t always flawless.

Given the high price tag, there are better options out there if you’re happy with photos that are just ‘very good’. But if you want the absolute best photography experience out there, the Xiaomi 15 Ultra is the phone for you.

However, it’s also worth considering the regular Xiaomi 15, which is more compact and affordable but retains dual-SIM support. Neither are available in the US, though.

After Oppo decided not to release its Find X6 and Find X7 series flagships outside China, the Find X8 series marks a triumphant return to Europe. Sadly, its launch hasn’t been extended to include the US.

Both the Find X8 and Find X8 Pro are excellent phones, but the latter has the slight upper hand. It’s powerful, good-looking, offers amazing battery life and has plenty of software perks.

But it’s the cameras that set it apart from rivals, and turn a great phone into a superb one. For pure image quality, it’s probably only the Xiaomi 14 Ultra that can rival it right now for UK buyers.

The phone isn’t without its compromises – there are a couple of small camera downgrades compared to the Find X7 Ultra, while the software takes some getting used to – but there’s no doubt that the Find X8 Pro is up there with the very best phones right now.

The inclusion of support for two physical SIM cards only sweetens the deal.

With a starting price of just £329/$379, the Nothing Phone (3a) is one of the most affordable mid-range phones out there. But for most people, there’s no need to spend more, especially when it supports dual physical SIM cards in all markets where it’s sold.

The Phone (3a) offers an impressive combination of premium, unique design, rapid performance and great battery life. The display is a slick 120Hz OLED and Nothing’s take on Android 15 is a compelling one, especially with up to seven years of updates.

The main compromise is the cameras, but the 50Mp main, 50Mp telephoto and 32Mp selfie lenses still outshine many rivals at this price. The 8Mp ultrawide is the big disappointment, but that won’t be solved by paying more for the (3a) Pro.

Overall, the Phone (3a) is an impressively well-rounded phone at a fraction of the price of flagships. Unless you really care about photography, AI features or the absolute best performance, the phone will serve you well.

When you think of flip phones released in 2024, Samsung’s Galaxy Z Flip 6 is probably the first one that comes to mind. However, the Razr 50 Ultra (or Razr+ (2024), depending on where you’re based, is a better choice for most people.

While both devices support dual SIM outside the US (but not in it), the Razr has the upper hand in some other key areas.

The 4-inch, 165Hz outer screen is the big one. Not only is it significantly larger than rivals, but you can run any app you like on it without any complicated workarounds. The 6.9-inch, 165Hz internal display is just as impressive, with a crease that’s barely noticeable.

While not quite as good as the best camera phones, the Razr 50 Ultra’s rear cameras can take great shots in a range of environments. However, Motorola has gone for a 2x telephoto rather than an ultrawide lens, while the internal selfie camera isn’t very good.

But with slick software (despite some cover screen bugs), solid battery life and decent charging speeds, Motorola is onto a winner. The Z Flip 6 is better in some areas, including long software support, but the Razr is the better all-around pick for most people.

If you’re looking for something more affordable, consider the regular Razr 50 instead, which also supports dual SIM outside the US.

The OnePlus Nord 4 is the best mid-range phone you can buy right now. It’s a better choice than the Pixel 8a for most people, and has the added benefit of supporting dual-SIM cards.

That starts with superb build quality, with one piece of sturdy aluminium extending across the back and sides of the phone. At the front is a gorgeous 120Hz OLED screen, supplemented by strong performance and all-day battery life.

Provided you’re a fan of the design, the compromises here are concentrated around the cameras. There’s no telephoto lens, meaning zoom shots are disappointing, while the ultrawide OnePlus has opted for instead flatters to deceive.

However, if you primarily use the main lens anyway, you won’t be disappointed. And with six years of security updates, the Nord 4’s longevity is one of its key strengths.

Overall, it’s the leading choice if you’re in the market for a mid-range Android phone, whether you need dual-SIM support or not.

CMF, Nothing’s sub-brand, has previously focused on wearables and audio products.

But its first attempt at a smartphone is an undoubted success, combining a fun look with solid core features and an impressively low price tag – just £209/$199.

Its design is the clear highlight, with a back panel that can easily be swapped out and an attachment for a lanyard, kickstand, or card wallet, all of which CMF sells as optional extras. However, even if you don’t care about any of that stuff, the Phone 1 has strong performance and an attractive display, both of which are must-haves on a modern smartphone.

Battery life is decent, while Nothing’s unique take on Android combines a unique look with no bloatware.

The lack of NFC (and so no support for contactless payments) is the biggest potential dealbreaker, while the cameras and water resistance could do with work. Samsung’s Galaxy A15 5G or A15 4G are the cheap phones to get if you value long software support, too.

But as a complete package, the CMF Phone 1 is the best all-rounder in the budget smartphone market right now. If you want a cheap, reliable phone that retains dual-SIM support, this is the device for you.

If you want a mid-range dual-SIM phone that could easily pass as a flagship, the Xiaomi 14T is for you.

It looks and performs a lot like the regular Xiaomi 14, yet starts at just £549 in the UK. Sadly, it’s not available in the US.

And there’s a lot to slick here, including a premium design complete with a stunning large OLED display. The cameras are surprisingly great, despite being a clear step down from Xiaomi’s class-leading 14 Ultra.

Solid battery life is supported by impressive 67W fast charging, even if the necessary charger isn’t in the box and there’s no wireless charging.

This is a phone with almost no hardware weaknesses, though the software is still underwhelming at times. Google’s Circle to Search feature is genuinely useful, but Xiaomi’s own AI attempts aren’t always successful.

Xiaomi’s commitment to four major OS updates and five years of security patches is solid, though. And as an all-rounder, you’ll struggle to find anything better at this price point. You could step up to the 14T Pro, but the extra £150 (it starts at £699) simply isn’t worth it for most people.

The Galaxy A16 5G is an unremarkable budget phone, but it’s also very easy to recommend. It’s an affordable dual-SIM phone that looks the part and offers a great display and strong main camera.

Software is another key strength, with Samsung’s slick One UI skin and a full six years of updates. Performance is the main area of compromise, though we’ve only tested the version that uses Samsung’s own Exynos 1330 chipset. If you live in a market where it uses the MediaTek Dimensity 6300, your experience may be different.

The secondary cameras also aren’t great, while battery life is actually worse than the previous Galaxy A15 5G. Though neither should be dealbreakers, especially when you’re paying so little and getting so much elsewhere.
