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

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.

Who should buy the OnePlus 13?

Users who prioritise battery life over everything else, and super fast charging to go along with it.

The cameras are still bested by the Galaxy S25 Ultra, and arguably even by the cheaper Xiaomi 14T.

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.

Who should buy the Xiaomi 15 Ultra?

Anyone who wants next-level cameras above any other feature – it’s like having a DSLR in your pocket.

Xiaomi’s take on Android still falls behind the experience you’ll find on Samsung, Nothing and OnePlus phones.

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 15 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.

Who should buy the Oppo Find X8 Pro?

Consumers who don’t mind spending a bit more to get an amazing across the board experience that leaves you wanting for nothing.

It’s a small gripe but the selfie camera doesn’t have autofocus, which isn’t great for content creators who rely on the front-facing sensor.

With each generation, Samsung’s book-style foldable phones have seen a handful of iterative updates but it’s in the Z Fold 7 that it feels as if the concept has finally hit its stride. 

If you’ve ever held one of the earlier Z Folds before then you’ll notice right away just how far Samsung’s engineering has come in terms of making its foldables as slim as possible. Being just 4.2mm thick when unfolded, the Z Fold 7 is very lightweight in the hand, and it no longer feels uncomfortable when stored away in a pocket.

Despite having a slimmer frame, Samsung has improved the durability of the phone via the new Advanced Armor Aluminium casing which allows the device to take more knocks and drops without issue. This also pairs with the tougher Gorilla Glass Ceramic 2 which coats the display, keeping scratches at bay.

All of this runs on the super fast Snapdragon 8 Elite for Galaxy chipset which handles everything from everyday tasks to high-end gaming. You still get a great visual experience regardless of which display you use, with a 120Hz AMOLED panel in both the interior and exterior screens.

Who should buy the Samsung Galaxy Z Fold 7?

Those who want a productivity powerhouse from their smartphone with tons of work-friendly functionality.

The price is astronomical, with even the Galaxy S25 Ultra being much cheaper, plus the US-model does not have dual-SIM capability.

The Xiaomi 14T is one of those wild phones that’s hard to believe actually exists. The reason why this is the case is that in spite of its relatively affordable £549 price tag, the phone boasts a user experience that is far more akin with what you’d find on phones much closer to £1000.

The design is incredibly sleek, in fact it almost looks a tad like the super premium Samsung Galaxy S25 Edge to a degree, and it’s IP68 rated so you won’t have to worry about dust or water ruining the device as you go about your day.

In classic Xiaomi fashion, it’s the cameras that shine above all other features, largely thanks to its enduring partnership with Leica. We were so impressed with the daytime shots the Xiaomi 14T was able to capture that in some instances, it most certainly outperformed the iPhone 16 Pro, and given how great that phone’s cameras are, that’s saying something.

What ties the whole thing together is the performance of the MediaTek Dimensity 8300 Ultra chipset. Working alongside 12GB RAM, the processor is more than capable of letting you jump quickly from one app to the next. There’s also speedy 67W charging that can nab you just over 50% of the battery back from a 15-minute top-up.

Who should buy the Xiaomi 14T?

Anyone who’s tied to a fairly strict budget and wants to get the most bang for their buck.

The lack of wireless charging can be an issue if you need to regularly top up your phone throughout the day.

Over the last few years, Honor has continued to show why it’s a force to be reckoned with in the premium handset space, and the Magic 7 Pro is an impressive culmination of everything the company has learned so far, alongside a handful of new AI-driven features.

For starters, if you’re ever worried about damaging your phone as you go about your day, then the Honor Magic 7 Pro can most definitely help to alleviate that anxiety. With a joint IP68 and IP69 certification, the phone is powerful enough to withstand high-pressure water jets firing at up to 80°C.

The Qualcomm Snapdragon 8 Elite chipset sits under the hood and paves the way for buttery smooth performance. It’s the type of leap in power that you’ll notice the moment you pick the phone up and start using it – everything just loads at a much faster pace, and it’s bolstered by the massive 512GB storage allowance.

Of course, as with any dual-SIM phone, you can’t really have the handset out of action for too long whilst it’s charging, and thankfully the Magic 7 Pro’s charging speeds can have you sorted in next to no time. Whether that be the 100W wired charging or the 80W wireless charging, you have the ability to get from 0% to 100% in as little as 33 minutes.

Who should buy the Honor Magic 7 Pro?

Folks who prioritise having tons of storage and super fast charging options in one device.

If you want a phone for the long-haul, you’ll get a greater period of software updates from the likes of Samsung and Google.

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.

Who should buy the Nothing Phone (3a)?

Budget-conscious buyers who want a great user experience that doesn’t break the bank.

The ultra-wide camera isn’t great, and unlike most budget/mid-range phones there’s no charger included.

Nothing sub-brand CMF’s second phone might adopt the ‘Pro’ name, but it’s still very much a budget phone. And with a starting price of just £219/$279 (more storage in the US), you won’t find a better handset for the money. The fact it supports dual SIM cards is the icing on the cake.

What makes the Phone 2 Pro so special? Essentially, it takes everything that made the CMF Phone 1 so good and makes it significantly better, in exchange for only a small price increase.

We’re talking two brand-new camera sensors, with the main lens also getting significantly better. For the price, you can expect some of the best photos around.

Add that to a brighter, more accurate display, a nice performance boost and the all-important NFC that was missing from the original (enabling contactless payments), and the Phone 2 Pro has a lot going for it.

The standout, customisable design remains, as does Nothing’s user-friendly take on Android 15. The three years of OS updates are a little underwhelming, while you don’t get full water or dust resistance, but the CMF Phone 2 Pro undoubtedly has a lot going for it.

Who should buy the CMF Phone 2 Pro?

Anyone who isn’t able to spend more than £300 on a phone – this handset goes above and beyond its budget price tag.

With only an IP54 rating, the phone isn’t quite as well suited to being used in the great outdoors.

Even though Samsung was the first big brand to really bring foldable phones to consumers on a global scale, in the last few years the company lost a fair amount of ground to the likes of Motorola and Oppo, but that’s finally been rectified in the excellent Samsung Galaxy Z Flip 7.

Just by looking at the phone, you can tell right away that this is a big upgrade over the Galaxy Z Flip 6 as it features a much larger outer screen than before. The exterior display now covers almost the entire surface area of the phone’s lid, making for a more immersive experience that doesn’t feel compromised.

The internal display has also been upgraded to a slightly larger 6.9-inch panel, making it great for productivity apps, such as typing up an article in Google Docs or re-arranging your to-do list in Notion.

Arguably the biggest allure from a consumer perspective is the promise of seven years of updates from the time of launch. If you are looking to go all in on one handset, it’s nice to know that the one you buy will be supported for quite some time to come, so you don’t have to worry about upgrading in the near future.

Who should buy the Galaxy Z Flip 7?

Anyone who wants a phone with a large screen but a smaller footprint, making it easier to carry around.

The phone is easily bested by other picks in this list when it comes to battery life and charging, and there’s no dual-SIM version in the US.
