If earlier, in order to install a SIM card in a smartphone, it was necessary to remove the back cover and remove the battery, now everything is a little different - phones are becoming thinner, and manufacturers are trying to make their cases (conditionally) not collapsible. How to insert a SIM card into Samsung and start fully using your mobile device?
Instructions
At the moment, in almost all modern smartphones, the installation of SIM cards and memory cards is very similar to each other.
Features of Samsung phones A 30 and A 20
The Samsung Galaxy A20 smartphone is a high-quality device with a frameless display, rounded edges and a shiny back cover. It has a large screen diagonal of 6.4 inches and has two cameras for creating high-quality images. The device has an 8-core CPU, 3 GB of RAM and 32 GB of internal memory. NFC, Bluetooth 5.0 and other features are provided.
The Samsung Galaxy A30 is very similar to its brother. It also features an edge-to-edge display, curved edges, and dual cameras. The screen has a diagonal of 6.4 inches, which has a high level of contrast and picture clarity. On board there is a dual-core eight-core processor, 3 GB of RAM and 32 GB of its memory. There is also a version with 4 GB and 64 GB respectively.
A special feature of both Samsung devices is the ability to install two SIM cards at the same time and an additional memory card. Each element has its own connector. If your task is to insert a SIM card into your phone, consider the following features:
- The trays where you need to insert a SIM card into the Samsung A30 and A20 are located at the top left (on the end of the smartphone). This is the standard arrangement for many phones from the South Korean manufacturer.
- SIM card size is Nano.
- The card holder has three individual connectors. You can install SIM cards in two of them, and an SD card (micro) in another.
- To remove the tray, you need to use a special product in the form of a thin pin curved at the end.
Knowing where to insert the SIM card into the Samsung A20 and A30, you can easily do this job. The main thing is to follow the step-by-step instructions below.

Video review
I would like to dwell on the latter in more detail. The basic version will cost about 360 dollars, and for the top version they ask for 430. Agree, quite expensive. The price is also due to additional options that competitors do not provide. In any case, it will be suitable for fans of the brand, and I would recommend switching from the A51 to a more recent solution. Fans of Chinese companies should look for something else.
Most recently, Samsung released 3 new A-series smartphones. These are Galaxy A 32, Galaxy A 52, Galaxy A 72. Smartphones are aimed at the popular mid-price segment, which ranges from 7 to 15 thousand UAH. As you know, it is difficult for Samsung to compete in this price range compared to the Chinese, but perhaps this time they will succeed.
As I said above, the company presented 3 smartphones in total, and we decided to start the review with the Samsung A52. In my opinion, this device represents, so to speak, the middle of the middle. That is, of all three, this device has good value for money, and it should sell more and better than its brothers. But only time will tell, but now we’ll go through the smartphone itself and see what the company has rethought over the past year.
How to insert a SIM card into Samsung A30 and A20: algorithm of actions
The manufacturer has done everything possible to simplify the process of installing a SIM into the phone. Samsung has moved away from the outdated method, which requires removing the back cover, removing the battery and then replacing it. Now a special slot is provided at the end and is completely independent from other elements of the smartphone.
Let's look at how to insert a SIM card into the Samsung A30 and A20. Let us immediately note that the installation instructions are the same for both devices, so it makes no sense to separate them.
The algorithm of actions is as follows:
- Find the slot where you need to insert the SIM card. As already noted, it is located at the top left side when looking at the smartphone screen.
- Disconnect the device completely to avoid software failures when replacing the SIM card.
- Find the special tray removal tool. It should be in the box with the Samsung phone. If the device was bought secondhand, you can use any thin metal object. The optimal solution is a paper clip.
- Insert the tool into the thin hole at the bottom of the card holder and press down. The correctness of the actions is confirmed by a quiet click and the opening of the tray.
- Remove it from the connector. There will be three holes - two for SIM and one for SD card (Micro).
- Install one or two SIM cards at once, if necessary. First look at how to insert a SIM card into Samsung to avoid mistakes.
- Return the tray with the SIM card installed in it to its place. Make sure you insert it the right way. Sim cards should be face down.
- Bring the card holder until it clicks and make sure it is locked in the Samsung smartphone.
That's all. If you managed to insert a SIM card into the A30 or A20, turn on the phone and make sure that it is detected in normal mode. Try calling, sending SMS and going online.
Camera
Now let's move on to the camera block. There are 3 of them on the back panel. The first camera is 64 megapixels with optical stabilization, f/1.8 aperture and autofocus. The second, already familiar to everyone, is an ultra-wide-angle 12-megapixel camera with an f/2.2 aperture and electronic stabilization.
The third, which I think no one needs, is a 5-megapixel camera with an f/2.4 aperture and a 5-megapixel auxiliary module for determining the depth of the scene. Oh yes, I almost forgot, the front camera here is 32 megapixels with an f/2.2 aperture. Now that we're done with the camera's characteristics, let's move on to the tests.
This year, optical stabilization was added to the Samsung A52. I would like to note that its presence has significantly raised the quality of images to a decent level compared to last year. During daytime shooting, the device performs well, just like most smartphones. Detailing is at a good level.
Thanks to the vaunted stabilization, it is extremely difficult to get a blurry photo. The photos come out in Samsung style - more saturated and vibrant than those of competitors. Just something to post on Instagram.
Samsung Galaxy A52 camera test: assessing photo quality
Night shots on the A52 come out good. I will say even more, he takes better photographs than his competitors. There is minimal noise in the photo, detail in dark areas is at a decent level.
It is worth noting that by default the phone shoots at 16 megapixels; in the camera settings you can switch to 64 megapixels. In fact, you won't notice any major changes, except that when you zoom in on the image, more details will be visible.
There is also 2x zoom and 10x software zoom. I don’t know how often you use this feature, but I don’t pay much attention to it. There is no need to talk long about “shirik”. A 123-degree viewing angle helps you capture everything that matters in the frame. There is no blurring around the edges of the photo, the dynamic range is normal. In general, it will do.
Portrait mode is also nice. Not to say that the additional module solves the problem, for me it’s self-indulgence. The object in the frame is determined correctly, due to which there is no noticeable blur in unnecessary places. Well, it’s hard to find fault with the quality of the photo itself.
Macro photography just exists. You still need to try to take a really high-quality photo. Perhaps my hands were shaking too much and the pictures were blurry. Only after 5 times it was possible to look at them.
The front camera is a bit disappointing. The pictures come out not to say very bad, but for me, the sharpness is too high. Also, color rendition is poor. The photos are not entirely natural, perhaps you need to tweak them in the settings.
Based on the video, Samsung A52 can be praised. It shoots in 4K at a frame rate of 30 per second. If you lower the resolution to Full HD, the smartphone will be able to shoot up to 60 frames per second. There is enhanced stabilization, which helps a lot when shooting. The sound quality is recorded at an average level.
Recommendations for installing a SIM card
To correctly insert a SIM card into the Samsung A30 and A20, it is important to take into account a number of rules. Let's highlight the main ones:
- Always turn off your phone during the replacement process. This precaution allows you to avoid malfunctions of the device. It is possible to install a SIM card even when the device is turned on, but then difficulties may arise with identifying the new card. It is better to avoid this mode.
- If the size of the SIM card does not match the dimensions of the slots in the tray, the SIM card must be cut to Nano size. An alternative option is to get a new card from the operator. Please note that if you cut it, there is a high probability of damage to the microcircuit and failure of the SIM card.
- Avoid using excessive force when removing and installing the tray. Removing or inserting the card holder does not require much force. If you overdo it, there is a high risk of damaging the slot.
There is one more important point. If you don’t have a special tool, try to use products with blunt ends to avoid damaging the internal elements of the smartphone.
Iron
And so we gradually come to the point that Samsung knows how to draw conclusions and learn from its mistakes. Finally, in the mid-price segment, they replaced their proprietary Exynos processors with Snapdragon and Mediatek.
True, this cannot yet be noticed in all the company’s smartphones, but they are already taking the first steps for the better. Although, on the other hand, some kind of competition is lost, which is also sad. But that’s not about that now.
So, on board is not the latest, but still far from old, Snapdragon 720G paired with Adreno 618 (500MHz) graphics. Processor frequency 2.3 + 1.8 GHz. It is made using 8-nanometer technology. In practice and in feel with this processor, the performance of the Samsung A52 has increased compared to last year's A51.
The phone works quite quickly. I didn’t notice any microfreezes or “lags”. On top of the operating system is the proprietary One Ui 3.1 shell. This is still the same One Ui that you all know very well, with its pros and cons.
According to the tests, the smartphone made me quite happy. When checking for throttling, which lasted 30 minutes, the processor produced an average of 97% for up to 20 minutes. Afterwards I dropped the power to only 87%. Agree, this is a very good indicator.
At the same time, the smartphone was slightly warm. It is not known what vat of potion Samsung put this device in, but it bore fruit. It must be a cooling issue. But this can only be known after opening it. Let's leave this for other bloggers. As I already wrote (or said?) earlier, in simple tasks such as messenger or non-resource-intensive processes, the smartphone works normally and without microfreezes. But what about games?
Everything here is at an average level, and you shouldn’t expect anything more. For example, in the game ShadowGun Legends at high graphics settings, the smartphone showed 36 FPS. Which, you see, is a good indicator for this smartphone. Of course, if you compare it with its competitors, its FPS is higher and the game is more stable.
At the same time, as with the throttling test, the smartphone was only warm and did not evoke the desire to put it in cold water. In general, it’s good compared to its competitors, but in general everything is at a confident average level. Samsung can give itself a small plus for this in the fight against Chinese brands.
Installation problems
Let's say you managed to insert a SIM card into a special slot on the Samsung A30 or A20. But for some reason the phone does not recognize the SIM. There could be several explanations for this:
- installation error;
- SIM card blocked by operator due to long-term non-use;
- damage to the tray or SIM card;
- Incorrect settings in the Samsung SIM cards section.
If such difficulties arise, try restarting the device, inserting the SIM card into another phone, or moving it to the second slot. In most cases, the problem can be resolved by the steps discussed above.
Another situation is the inability to insert a card slot into the connector. The reason may be incorrect installation of the SIM card or the presence of burrs after cutting it. Check again that nothing is interfering with the SIM installation and that it is installed correctly.
Conclusion
To avoid problems, handle trays and card modules with care. Do not allow dirt to get inside the phone, carefully trim the edges. If you can’t do something, contact a specialist. The gadget will be useful to you, don’t break it.
