Guide: Nano SIM Cards
If you look at current models of smartphones in the online shop, you will see that all these models are being built ever narrower and more compact.
With this development it was inevitable that the Sim cards also had to shrink in size. In the past, credit card sizes were commonplace, but today more and more Nano Sim cards are being sold.
A mobile phone with Nano Sim is considered to be the current standard. Why new products are equipped with a Nano Sim card, you can read in the following lines. Exact results for the individual models of the manufacturers can be found below in the in-depth reports.
How is a Nano Sim card size defined?
If you want to buy a smartphone with Nano Sim, you will usually find very current models or novelties here. While in the past the Mini Sim cards or the Micro Sim cards were considered the measure of all things, Apple, Samsung, Huawei or Sony in particular now only use Nano Sim cards.
The Nano Sim cards are the smallest Sim card sizes that are currently available on the market according to some test report summaries.
The Sim card is very important because it is the heart of every smartphone. If you buy a smartphone without a contract and also operate it without a sim card, you will not be able to make phone calls or use other features of the smartphone optimally.
If you buy a model with a contract, then the tariffs will be designed in such a way that you can access the Internet on the go, for example. Experience shows that Nano Sim cards are also standard for prepaid tariffs.
Basically there are four different sizes of sim cards on the market. For a long time the full size sim cards were considered the measure. These sim cards were the first sim cards that were available for a smartphone. However, these models had decisive disadvantages.
They had the size of a cheque card, which cannot be used with today’s smartphones without the smartphone being too big. So over the years, the developers have continued to reduce the size of the smartphone. First came the Mini Sim cards, then the Micro Sim cards and now the Nano Sim cards are considered the ideal Sim card size.
The Nano Sim card is also called 4FF Sim card according to some recommendations and test report summaries. In general it is almost 40 percent smaller than the Micro Sim card. The Nano Sim card was first used by Apple in 2012.
|Name of the SIM Card||Size|
|Mini SIM||0.98 in X 0.59 in|
|Micro SIM||0.59 in X 0.47 in|
|Nano SIM||0.48 in X 0.35 in|
|Full Size SIM||3.37 in X 2.12 in|
Advantages of a Smartphone with Nano Sim Card

- Since the slot is very small, the devices normally always have an SD card slot
Disadvantages of a Smartphone with Nano Sim Card
- Old Smartphones need an Adpater
How to find the Best Smartphone with Nano Sim Card
If you look at our Best Smartphone with Nano Sim Ranking at the top, you will see a ‘Smartphones with Nano Sim’ comparison including the Winner, which is not the cheapest Phone, but the best in terms of Performance.
If you are looking for a cheaper alternative, take a look of our ‘Best Price’ Category winner in the Ranking, which has a much cheaper price with still great Performance.
Ranking First: Samsung Galaxy S20+ Plus 5G
- Best Performance
- Good acoustics and Radio characteristics
- Awesome camera with 3 focal lengths, Top photo quality and 8K videos
- Expensive, but Great Performance always costs
Design, workmanship and choice of materials are once again absolutely top class, just as you would expect from Samsung. The design is based on the Galaxy S20 Ultra, which means that the case is made of Gorilla Glass 6 at the back and front, which is held together by a painted aluminium frame.
In the US, 3 colours are offered, the classic black (“Cosmic Black”) and grey (“Cosmic Gray”) are joined by light blue (“Cloud Blue”) for a fresher look. In all variants the back is shiny and magically attracts fingerprints; a well-known problem that is easy to come to terms with.
Compared to the Ultra, the camera unit is smaller at the back and doesn’t stick out as far, which is immediately noticeable in your pocket. The comparison with other smartphones with Nano Sim Cards also shows: for a 6.7 incher, the Galaxy S20 Plus 5G is very light and compact.
It is a bit narrower than the average and thus lies very well in the hand. In addition, there is an optimally balanced weight distribution and a power button positioned exactly in the right place. This smartphone with Nano Sim Card is a pleasure to hold in your hand – in contrast to the S20 Ultra, which quickly becomes too heavy.
And in contrast to the larger and more expensive sister model, you hardly have to make any concessions with the display. The diagonal shrinks from 6.9 to 6.7 inches, which is still huge by smartphone with Nano Sim Card standards. As in the new Note series, the recess for the front camera is point-shaped and hardly disturbs the view of the display.
Samsung does without a curved display edge, which was previously a trademark of the S series. Nevertheless, the Koreans build close to the edge, with an edge that is only slightly curved.
The renouncement of an edge display not only minimizes wrong input with the ball of the thumb, it also allows Samsung to stick a display protection foil on ex works.
A treat for the eyes is the high refresh rate of 120 Hertz, which allows a noticeably softer scrolling while surfing and in apps. The factory setting is 60 hertz, and if you increase it to 120 hertz, the screen resolution is reduced from 3,200 x 1,440 pixels to 2,400 x 1,080 pixels in order to conserve the battery.
While reducing the resolution has no visible effect (you have to get very close with a magnifying glass to see anything), you notice the difference between 60 and 120 hertz immediately. We therefore recommend activating 120 Hertz, even if this reduces the battery life. More about the concrete effects later.
The display plays along with the front in terms of quality, and in comparison to an S20 Ultra, you don’t have to make any concessions.
The maximum brightness is low at 377 candelas, which is typical for Samsung, but in a bright environment the display regulates up to 1060 candelas (for a short time), which is a record-breaking brightness that ensures good readability even outdoors. The contrasts we determined at different ambient brightness levels are good, but not outstanding.
The RGB color space is greatly expanded, and Samsung covers a wider range here than other OLED smartphones with Nano Sim Card like the Pixel 4 or the iPhone 11 Pro. In return, however, they are somewhat more stable in terms of viewing angle and contrast.
The Galaxy S20+ 5G is offered with two processor combinations: With the in-house Exynos platform (Exynos 990 + Exynos modem 5123) and with the Qualcomm Snapdragon 865 + modem X55. Availability depends on the region: the Exynos variant is available in Europe and South Korea, the Snapdragon variant is sold in the USA.
Technically and in terms of performance, there are no major differences, with a dedicated artificial intelligence engine, a powerful GPU (Mali G77 / Adreno 650) and ultra-modern 7-nanometer EUV manufacturing technology, both offer the spearhead of what is technically possible.
However, both companies have not succeeded in integrating the modem on the SoC, so it is physically separated, which on the one hand increases space consumption and on the other hand lengthens the conductor paths, thus increasing energy consumption. The only company that can currently manufacture the SoC and 5G modem integrated is Huawei with the Kirin 990.
The test sample we had in front of us was equipped with the Exynos 990. It is clearly more powerful in benchmarks than the Exynos 980 (Galaxy S10), but doesn’t quite reach the performance of an Apple A12 (iPhone 11).
But that’s nitpicking in the end. One thing is clear: the Galaxy S20 Plus 5G is hard to push to a limit in terms of performance, which is also due in part to its generous 12 GB RAM.
In terms of sound, the Galaxy S20 Plus 5G is convincing all along the line, the stereo speakers deliver an excellent sound on the level of its predecessors, Dolby Atmos is supported. The internal memory of our test sample is almost inexhaustible with 512 GB, if you still need more, you can expand via micro-SD.
Alternatively, the slot holds a second SIM card, so the Galaxy S20 Plus 5G can handle dual SIM. Strong: An eSIM can be integrated via the settings menu as an alternative to the second physical SIM, and with the three S20 models, Samsung also supports the virtual SIM card for the first time.
The rest of the connectivity is also state-of-the-art with 5G, LTE Cat 20 (2 Gbps down and 150 Mbps upload), the latest ax-WLAN, Bluetooth 5.0, NFC and USB C 3.2 connection. Unfortunately, a jack socket is missing – it was still included in the predecessors.
The new version 2.1 of Samsung’s user interface One UI, which is based on the current Android version 10, pleases with a tidy design, which clearly presents the exuberant variety of features and extras. The differences in comparison with One UI 2.0 (Note-10 and S10 series) are manageable.
Right at the top is the new “Quick Share”-DeepL access in the status bar, which, like Apple AirDrop and Huawei Share, makes it extremely easy to share content with people nearby. The personalized news overview Bixby Home, which is located to the left of the home screen, is replaced by Samsung Daily, with minor layout changes.
There are also some cosmetic changes to some app icons, and the homescreen can be excluded from dark mode so that it doesn’t change its transparency or brightness when activated.
Very strong and always worth a mention: The desktop mode DeX, which turns the Galaxy S20 Plus 5G into a PC replacement. This requires a USB-C to HDMI adapter as an interface between the smartphone with Nano Sim Card and a monitor or TV set.
When all three are connected, DeX starts by itself and allows you to watch videos on a big screen or work like on a PC by connecting keyboard and mouse via Bluetooth.
In terms of acoustics and radio characteristics, the Galaxy S20 Plus 5G is very well-placed; other smartphones offer a higher volume during calls, but not the same voice quality, and the noise suppression works at a very good level.
The transmission and reception characteristics are in the good midfield in GSM, UMTS and LTE networks. We have not tested the new 5G standard.
The camera makes the biggest difference compared to the Galaxy S20 Ultra, the Galaxy S20 Plus 5G has to leave plenty of room for improvement, at least in terms of equipment. In terms of quality, the differences are much smaller than the technical data would initially suggest.
Samsung once again relies on a camera system with three lenses, which gives the photographer the greatest possible flexibility from ultra-wide angle to tele zoom.
However, the zoom factor is smaller on the Galaxy S20 Plus 5G (3x instead of 4x), and the main sensor is also weaker. Instead of the high-resolution Isocell Bright HM1 with 108 megapixels, a 12-megapixel sensor has to suffice.
But it doesn’t have to hide behind the S20 Ultra, as the pixel size (and thus light sensitivity) is more than decent at 1.8μm and our measurements show that the quality is at a level that is only slightly behind the S20 Ultra. This applies to both good lighting conditions and low light.
The zoom lens delivers a surprisingly good quality, although Samsung doesn’t realize the zoom optically over the focal length, but digitally, via cropping on the sensor, which offers enough reserves for this with the high resolution of 64 megapixels.
The photo quality of the zoom lens is better at three times magnification than on the Galaxy S20 Ultra with five times zoom. If you adjust the zoom levels (the S20 Plus 5G to 5x and S20 Ultra to 3x), the Galaxy S20 Plus 5G is clearly better. Conclusion: the Galaxy S20 Plus 5G has a greatzoom.
With the Galaxy S20 Plus 5G you also have the option of taking high-resolution photos with a resolution of 64 megapixels, Samsung uses the full resolution of the zoom lens at normal wide-angle focal length for this.
Our measurements show that you’re well on your way with it: in good light, the photographer gets more details out of the shots; the extra sharpness is a gain. In bad light, however, the noise level is so high that it’s better to switch back to the standard resolution of 12 megapixels.
It is also recommended to shift down a gear with the video camera. This is because the much advertised 8K video mode turns out to be of little use, just like the S20 Ultra. In contrast, the videos look really good at 4K and 60 fps.
All in all, the Galaxy S20 Plus 5G’s camera system leaves a very good impression. The focal length range extends from ultra-wide-angle to telephoto, the photo quality is very good, and the setting options are varied. The drop in quality in comparison to the Ultra is small and should hardly play a role in the everyday life of most users.
If you look at the entire S20 series, the Samsung Galaxy S20 Plus 5G is the best choice for many users. Technically, the last meter may be missing, but that only bothers you if you are technically adept and always have to have the latest.
In return, you get a 6.7 incher with a convincing display and a versatile camera, which is still reasonably handy despite the huge display. The battery life could be a bit better, but is still within a good range. A very recommendable smartphone, which is why it’s ranking First on the best Smartphones with Nano Sim Card.
Ranking Second: Huawei Mate 20 Pro
- Good NFC Smartphone Performance
- Best Price
- Very Good Battery life
- Wireless charging is not supported
The design is already a bull’s eye – this is what a smartphone that scratches the 1000 euro mark must look like. Huawei is not reinventing the world, on the contrary. The basic structure is already familiar from Samsung and Sony: two glass plates that are bent on the long sides are held together by a metal frame that tapers as it bends.
This design has many advantages, as the phone with Nano Sim Card lies comfortably in the hand with the curved back, while the curved display at the front makes the display appear rimless. The metal frame gives the phone a great feel and stability.
But Huawei goes beyond the well-known in two respects: on the one hand, the imposing (and only slightly protruding) camera unit at the back is an eye-catcher, on the other hand, the long 18:9 display format is once again stretched, as the display at the top also reaches to the edge and is interrupted by a trendy notch.
Huawei thus achieves an aspect ratio of 19.5:9 that is suitable for cinema – this makes an impression and looks ultramodern.
The Mate 20 has a more classic look. The case is wider and the bend on the back isn’t as pronounced, the display lies flat on the front. The 18:9 format also appeals to all those for whom the Pro is too stretched (the display is unusual at first).
The P20’s display looks more powerful because the diagonal is a bit longer (6.5 inches instead of 6.4 inches) and the notch at the top is drop-shaped and thus so tiny that it hardly takes up any display area. The workmanship is flawless on both phones with Nano Sim Card.
Compared to the highly acclaimed Leica system of the P20 Pro, not only the arrangement of the lenses has changed. For the first time, Huawei has dispensed with a black-and-white optic and justified this step by saying that a 40-megapixel RGB sensor provides sufficient image information.
The Mate 20 Pro takes this over from its sister model, as does the 8 megapixel zoom focal length. A wide-angle lens with 20 megapixels is a new addition. The Mate 20 Pro thus covers a KB-equivalent focal length range from 16 to 83 millimetres – a unique feature in the smartphone world.
Even if the identical arrangement of the lenses suggests similarity, the Mate 20 comes with a different camera. It operates in a smaller focal length range (17 to 52 millimetres), because instead of a triple, a double zoom is built in.
In contrast to the zoom, the slightly different wide-angle is not relevant in practice. More conspicuous in this setting is the drop in peripheral light, as well as the slight perspective distortions. Both occur with both phones with Nano Sim Card and are due to the short focal length.
One can even say that Huawei has got the associated problems well under control. The second important difference besides the focal length concerns the sensors: Instead of a 20/40/8 megapixel combo, the Mate 20 has to be 16/12/8 megapixels.
Our laboratory measurements certify that both smartphones with Nano Sim Card have great image quality. The fact that the Pro model performs comparatively poorly in low light should not be overestimated, it is rather due to the unique image signal processing of Huawei and Leica: In low light, four pixels are combined (“quad binning”).
This reduces the resolution from 40 to 10 megapixels, at the same time the pixel area quadruples and each pixel can capture more light. Since the standardized procedure used in our laboratory measurements always provides the highest available resolution, we photographed with 40 megapixels.
This means: Due to the poor lighting conditions, the camera software activated quad binning, took the photo with 10 megapixels and then upscaled it to 40 megapixels – which it does not do in standard mode. This is because fine structures are lost in the process.
In the end, this confirms a truism: In low-light conditions, higher resolution has no advantages. If you take pictures in automatic mode, you’ll be very happy with both phones, at all zoom levels.
But ambitious photographers will reach their limits with the Mate 20, because if they push the sensor resolution in good light conditions, it will fall behind the Pro. Even in professional mode with the RAW option activated, the Pro model plays out this advantage.
And because the 40 megapixel sensor including quad binning is an essential prerequisite for the outstanding night shots of the P20 Pro and Mate 20 Pro, the sister model also comes off worse here.
Stronger zoom, higher resolution, better night shots – in these three areas the Pro is ahead of the rest. The fact that the Mate 20’s camera nevertheless plays in the top league only underlines how far ahead the Mate 20 Pro is.
An important unique selling proposition of the current iPhone generation is the face unblocking via Face ID. Apple has developed a particularly secure procedure that involves much more than a camera that optically records the face.
This is because the optics are flanked by an entire phalanx of sensors, the core elements of which are an infrared and a depth sensor. This enables a three-dimensional scan of the face at any time of day. The level of security is comparable to a fingerprint, and Apple excludes any deception with masks or photos.
Huawei takes a similar approach with the Mate 20 Pro with the “Face Scan”. According to the Chinese, they record about 30,000 points on the face. In contrast to Apple, however, face recognition is combined with a fingerprint sensor that is directly embedded in the touchscreen.
Scanning the fingerprint for the first time takes longer than we are used to from Huawei, but the recognition rate in our test was on the same high level as a classic sensor field. However, the fingerprint is only needed as an alternative in case the “Face Scan” fails, which was almost never the case in our test.
The procedure works without any problems in any light situation and also at an oblique angle and is just as comfortable as we know it from the iPhone X. The Huawei solution gains its special charm by combining two methods that are very convenient in themselves.
Even if you wear a scarf in front of your mouth in winter, or if the phone with Nano Sim Card is held in the direction of other people (to show photos, for example), you don’t have to enter a PIN with the Mate 20 Pro. The PIN is almost only required as part of the obligatory three-day security check – which is also useful, because otherwise there is a risk of forgetting the sequence of numbers
In line with the new biometric methods, Huawei implements a password manager in EMUI 9 that stores all usernames and passwords entered on the phone – a feature that not only iOS but also Samsung’s Android interface Experience UI has always been able to score against Huawei.
The password manager is supplemented by the extras that are already known and appreciated by Huawei: The owner can define apps that can only be opened by him via app lock, access is via PIN, face scan or fingerprint. The same applies to the “file safe”, which encrypts photos, videos and other files, and to the “private space”, a separate Android interface that can only be accessed with a fingerprint that has been specially stored for this purpose.
The Mate 20 comes with the same software functions, but carries the finger sensor on its back in the classic way, and the face unlocking is only done with the camera sensor.
The data transmission is also record-breaking: At its peak, 1.4 Gbit/s can be transferred, which corresponds to LTE Cat 21. The three-tier cluster design ensures the right balance of performance and energy efficiency: two high-performance cores with up to 2.6 GHz are flanked by two medium-performance cores (1.9 GHz) and four weaker ones (1.6 GHz).
In addition, the second generation of the Neural Processing Unit (NPU), optimized for AI applications, has significantly improved its performance. Huawei states that the image recognition rate has doubled to 4500 frames per second. This enables new applications, especially for the camera.
For example, during video shooting, a black-and-white filter can be placed over the background in real time while the person in the foreground remains in color. These and other filters don’t work perfectly yet, but they show the Kirin 980’s potential, and the fact that it has access to 6 GB of RAM on the Pro model and only 4 GB on the Mate 20 doesn’t affect everyday use.
The measured battery life is also absolutely top class: The Pro model achieves an outstanding 10:50 hours, the Mate 20 even a record-breaking 13:18 hours. So both phones with Nano Sim Card can easily be used for two days. In addition to this, there are good radio characteristics and good acoustics, so that it is difficult to find any points of criticism at all with these phones.
To answer the question asked at the beginning: In view of the large number of technical innovations and the excellent product quality in every respect, Huawei’s pricing is justified. The second place of the Mate 20 Pro in the best Smartphones with Nano SIM Cards speak for itself.
The Mate 20 Pro also won our ‘Best Price’ Category, due to its low price. So if you are searching for cheap but great performing Smartphone with Nano Sim Card, this model is your best Choice.
Ranking Third: ASUS ROG Phone 2
- High class Graphics unit for perfect Gaming performance
- Extravagant design
- Dual Camera with very good photo quality
- High Price Tag
The smartphone with Nano Sim Card is the Americans’ favourite gaming platform. According to a study by the market research institute GfK, 65.2 million Americans play on their mobile devices – 4.7 million more than in 2020. Last year, global income from mobile games amounted to almost 70 billion Dollars.
The virtual worlds are becoming increasingly complex. Apart from Candy Crush, there are now a number of performance-hungry top games that require powerful hardware to reach their full potential.
Asus has recognized the trend of Mobile Gaming 2020 and has launched its first gaming smartphone with the ROG Phone. The second generation we tested picks up where the first one left off.
The new ROG device is also trimmed for maximum performance, and the Taiwanese have put a lot of effort into making the phone perfectly suited for gaming.
Already the exterior is a real eye-catcher. Asus focuses on a martial design with matt black glass and many edges. Shimmering lines permeate the back, whose patterns are reminiscent of circuits.
The ROG logo in the middle of the case, which glows in gaming mode, and the outlet on the right side are also special. It is intended to allow warm air to escape and provide cooling during heavy use.
Like a brick, it still doesn’t lie in the hand, but is actually quite well balanced. The center of gravity has been chosen so that it can be used well, especially in landscape format during gaming.
Asus has built two pressure-sensitive keys into the metal frame to suit this. The phone with Nano Sim Card becomes a kind of gamepad because you can freely assign functions to them for each game. Two vibration motors provide a decent haptic feedback.
Meanwhile, the sweeping 6.6-inch OLED Display including fingerprint sensor is responsible for the visually impressive gaming experience. Thanks to the high refresh rate of 120 Hz and the short reaction time of one millisecond, games can also be fast-paced.
You’ll look in vain for streaks caused by too fast action. As high refresh rates like to put a strain on the battery, you can also reduce them to 60 or 90 Hz. The latter is a good middle ground and very pleasant for surfing, as the picture is then much clearer.
Moreover, the difference between 90 and 120 Hz is hardly noticeable with the naked eye and thus doesn’t justify the higher power consumption in everyday life.
Asus sets a resolution of 1080 x 2340 pixels, which is still sufficient for the display size. Content is displayed sharply and the colors look strong, but a bit cooler than usual. An HDR-10 support also provides greater color depth.
All in all, a good OLED is in sight, but its quality cannot keep up with similarly expensive phones with Nano Sim Card like Google Pixel 4 or Apple’s iPhone 11. The much cheaper Xiaomi Mi Note 10 also offers a better display.
Inside the ROG phone is a highly engineered heart, consisting of the overclocked top chipset Snapdragon 855 Plus with a clock rate of 2.96 GHz. The Taiwanese have also drilled out the graphics unit, which is supposed to offer 15 percent more performance than the standard configuration.
Together with the ample 12 GB RAM, the ROG Phone 2 achieves fantastic values in the benchmarks. The system performance of the phone is the best we have ever measured.
With this device you are prepared for any performance hungry game – also in the future. Full performance is also available in terms of connectivity: you can transfer data via USB 3.1 and write them to the 489 GB internal memory with USF 3.0.
If you spend 100 Euro more, the ROG Phone 2 is also available with 1 TB of storage, so it can also be used as an external hard drive if required.
For a delay-free gaming experience, the Taiwanese have also equipped the phone with four WLAN antennas – if you ever need to cover one of them with your hand. It almost goes without saying that Bluetooth 5, NFC and a jack socket are also on board.
If you want to use the stereo loudspeakers on the front, you can do so without hesitation for once. They support the DTS:X Ultra surround sound format and are really powerful – if necessary, they can even provide sound for a party.
In addition to the USB port on the bottom, there are two connectors on the long side. This allows you to either conveniently charge the device while playing in landscape format or connect various accessories such as an external fan.
For the normal smartphone with Nano Sim Card everyday life the ROG Phone 2 offers a dual camera, in which besides the normal optics (48 megapixels) there is also an ultra wide angle unit (13.2 megapixels).
The image quality is very good in both bright and dark environments, and the camera app also offers some features like RAW recording.
On top of that, the thick 6000 mAh battery ensures extended gaming sessions: In the runtime test the ROG Phone 2 reached an outstanding 11:20 hours. But once the battery is drained, the device is quickly ready for use again with the included 30-watt power supply.
The phone with Nano Sim Card doesn’t show any weaknesses in the reception characteristics and performs well throughout. Only the acoustics still need a bit of optimization.
All in all, the ROG Phone 2 can come out of the test with a “good” and misses the “very good” just by the devaluation in the handiness. Nevertheless, Asus has presented a very successful device with a refreshingly clear focus, which is why the ROG Phone 2 is ranking third on the Best Smartphones with Nano SIM card.
