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

The Galaxy S24 Ultra is the best phone you can buy, and the good news is that it supports two SIM cards.

It’s arguably the ultimate smartphone, packing almost every premium feature you can expect into one huge device. However, the gorgeous 6.8-inch display and built-in S Pen stylus are certainly worth it.

Other highlights include sublime performance from an overclocked version of the flagship Snapdragon 8 Gen 3 chipset and strong battery life from the 5000mAh cell. The cameras might not be the best on any smartphone, but they’re not far off, offering impressive versatility across four lenses.

Samsung’s One UI software is intuitive and relatively easy to use, and the company’s new AI features are genuinely useful. Throw in a class-leading seven years of updates and you’ve got yourself a superb phone.

Aside from the imposing design and relatively slow charging, the price tag is the main thing that counts against the S24 Ultra. But if you can afford it, you won’t be disappointed.

Xiaomi’s camera-focused flagship is the best phone around for photos, especially when combined with the flexibility of two physical SIM cards.

Let’s talk about those cameras, then. Alongside the Photography Kit accessory (sold separately), they transform the phone into a genuine DSLR replacement for many people. The image quality and versatility across all four 50Mp rear lenses and the 32Mp selfie camera is simply superb.

There’s lots more to like too, including a gorgeous display, stunning premium design and great performance. Battery life is strong, and you get a 90W fast charger in the box. From a hardware perspective, it’s hard to fault.

Aside from the price, the main reason you might not want to buy it is Xiaomi’s HyperOS software, which still contains a lot of bloatware and can get frustrating. But if you can look beyond this, the 14 Ultra will give you an unrivalled photography experience.

Looking for something more affordable? The regular Xiaomi 14 is a great alternative which also supports dual SIM.

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. The fact it

Both the Find X8 and Find X8 Pro are excellent phones, but the latter has a 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.

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.

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, 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.

The OnePlus 12 is significantly more expensive than the OnePlus 11, which was a great handset for the money. But this extra expense is justified – a stunning design, significant performance upgrade and the introduction of wireless charging make a real difference.

Its Snapdragon 8 Gen 3 chipset speeds through tasks with ease (including gaming), then combines with a 5400mAh battery for superb battery life. When you do run low, you can choose between 100W wired and 50W wireless charging, though the 80W charger in the box will be plenty fast enough for most people.

The 120Hz AMOLED screen is among the largest on any phone at 6.82-inches, but also one of the best. The slick software experience is also a joy to use, even if the four OS updates and five years of security updates are a small step down from the best around.

Rear cameras, a weakness of earlier OnePlus phones, are very good on the whole. But the ultrawide and selfie lenses aren’t the best, and the IP65 rating means it’s not protected against submersion in water.

Nonetheless, the OnePlus 12 still undercuts most flagships on price while offering a compelling experience. And with dual-SIM support, it’s impressively versatile.

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.

The middle phone in Samsung’s Galaxy S24 range isn’t quite the all-singing, all-dancing S24 Ultra, but it’s arguably a better phone for some people.

You still get most of the fundamentals of Samsung’s ultra-flagship, including a gorgeous large display, superb battery life, useful AI features and dual-SIM support. Samsung’s slick, AI-infused software also combines with a class-leading seven-year update commitment.

US buyers will still get the overclocked Snapdragon 8 Gen 3 chipset, but even the Exynos 2400 in the UK delivers strong performance.

If you can do without a stylus or loads of storage but still want a dual-SIM Samsung flagship, the S24+ is the phone to get.

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.

In 2023, the regular Galaxy A14 was a slightly better buy than the A14 5G. But this year, the A15 5G’s better performance and 5G connectivity give it the edge, and there’s no competition in the US – the cheaper A15 (4G) isn’t sold there.

Essentially, what you’re getting here is a cheap device that nails the fundamentals of a great smartphone. It has a well-designed, premium build that could easily pass for a much more expensive device. Battery life is excellent, stretching to two full days with light usage. And the 90Hz display is a joy to use.

The A15 5G might not have the AI features or seven years of updates from the flagship Galaxy S24 series, but One UI remains the best software you’ll find on a cheap phone. And Samsung’s commitment to four OS updates and five years of security patches is still better than any budget rival.

If you can put up with unremarkable performance, no official water resistance rating and mediocre charging speeds, the Galaxy A15 5G is easy to recommend. Adding dual-SIM support makes it even better.
