High technologies are developing rapidly. At the same time, progress often affects even the most familiar and unnoticed things that we use every day. For example, a few years ago, telephone SIM cards were of a standard size, but today they differ, and when purchasing a new mobile gadget, this parameter must be taken into account. Today we’ll talk about nano-sim, what is it, and how does it differ from traditional sim?

Nano sim and micro sim are the names of the dimensional parameters of SIM cards used in any device. The dimensions of the first are much smaller compared to micro and are only 12.3 * 8.8 millimeters (for micro 15 * 12 mm). Must be taken into account this moment when selecting a device, because a micro SIM may not fit into a port created for a different size, and vice versa.

This refers to the size of the plastic field with the chip. It itself has standard proportions - the same as those on traditional SIM cards.

Let's talk about dimensions

It should be remembered that SIM cards differ both in size and in the width of the sides. For example, in the micro format the lower distance from the chip is greater compared to the upper one, but in the nano format it is in the opposite order (so that you can make a cut corner).

SIZE (WHEN THE CARD IS POSITIONED VERTICALLY, CUT CORNER AT TOP, RIGHT)	MICRO	NANO
Left offset from chip	0.5 mm	Up to 0.3 mm
Chip offset to the right	2 mm	Up to 0.3 mm
Distance from the chip below	1 mm	0.5 mm
Chip distance from top	1.5 mm	0.5 mm
Maximum total card length	15 mm	12.3 mm
Maximum total map width	12 mm	8.8 mm

These are approximate figures, because providers appearance maps sometimes differ slightly, but this does not affect the operation in any way.

Historical information

Microsims appeared about seven years ago - exactly at that time this type gained widespread popularity, mainly among devices of Asian origin, but after some time European manufacturers began to use this development. Although it did not have enough time to spread widely, because a couple of years later the Apple corporation created a nano-sim, they went along with the new iPhones and iPads.

Asian manufacturers liked the innovation, and after a while, European developers began to attract the nano format. The difference between nano sim and microsim is not very noticeable, but quite noticeable, and the smallest format has not left the market for a long time, filling it more and more. This is the minimum acceptable parameter, because further compression will require a reduction in the width and length of the working chip, so the new SIM cannot be used in all models of gadgets known today. All mobile devices now work with a standard chip size.

Nano-SIM card, what is it and why did they change the size?

As noted, reduced nano dimensions were introduced about 7 years ago. This is due to the fact that smartphones quickly became more complex and were produced with more voluminous “filling”, while the scale of the device could no longer be increased. Well, this format allows you to save quite a lot of space.

For us, this difference is insignificant, but if we talk about microelectronics, it is almost prohibitive. In addition, it became possible to seriously reduce the port parameters for the card.

How to trim?

As you already understand, even if you change the size of the SIM card, the dimensions of the working chip do not change; this is not the difference between a nano SIM and a micro SIM. In fact, we are reducing the plastic field that surrounds it.

Many find it inconvenient to use a tiny nano card, because it is easy to lose, it is difficult to install, although it takes up little space under the cover.

Communication service providers sell ordinary SIM cards, but there are a couple of rows of markings in the plastic field. So you can extrude your format. The lines were cut according to the “matryoshka” type - sim standard, micro (first row of notches), nano (2nd row).

What should those who have an old large SIM card do, and after purchasing a new device it does not fit? The easiest option is to ask for help from your provider’s communication center. Many operators this service free. If for some reason the office does not make such replacements, we can say that the SIM card is lost and you want to restore it. After the replacement procedure, you should be given a new “plastic” with your phone, but with notches for all sizes. If your number is registered to someone else or you don’t have your passport with you, you can try cutting the card to fit a nano.

Many repair services that deal with mobile devices can offer SIM card cutting. You shouldn’t immediately think that this service is meaningless; as practice shows, there are people who use unofficial sims, or their card was registered in a different name (the office refuses the user in such cases).

What do we have to do?

Depending on the experience of the service where you go for trimming to a nano SIM, the cost of the service usually varies. There are specialists who charge up to a thousand rubles for this special service. if you have necessary tools, attentiveness, accuracy and ten minutes of free time, then you can handle it yourself.

If you are not sure that everything will work out for you, or you do not do it carefully enough, contact a specialist. Otherwise, the sim may stop working.

For trimming you need sharp scissors, a pencil and a ruler. The steps are very simple:

• measure with a ruler, draw with a pencil on the SIM card the sides that will be eliminated (there is a convenient template for this).

The cut corner remains, otherwise the card will not fit correctly into the cell.

• We cut off the margins, you don’t need to cut right along the line. It is better to approach her carefully (this way your Sim will not break during the procedure);
• We install the card in the device to check its functionality.

Some users say that even if you cut off a lot (without touching the chip), the SIM card will remain working. You just need to move it in place. If you cut and installed everything correctly, the smartphone will recognize the card.

You can simply stick the chip on thick paper of the desired size.

WITH technical point This option can help if something goes wrong. It can be difficult to stick it straight on your own, so it’s better to turn to the experts.

Now you know everything about the nano SIM card, what it is and how to cut it. We hope this material It will be useful for you, if you have any questions, ask in the comments.

As it became known from the presentation, iPhone 5 owners will need to change their SIM cards from micro SIM to cards of a new type - . But this is not always convenient; you have to go to the operator, bring your passport, and stand in line. Is it possible to have another, more easy way? To answer this question, let's first delve into history.

The development of nano SIM was carried out not only by Apple, but also by many other giant companies, such as Nokia, Motorola, RIM, etc.

Apple proposed this nano SIM card format, a standard arrangement of contact pads, but smaller in size:

To which Nokia developers proposed another option. In their opinion, such a card should be inserted into the phone like a memory card - on the side and without a SIM slot, and for these purposes the card was equipped with side protrusions:

But Apple said that SIM card too long and may get stuck in the classic micro-SIM connector...

Motorola and RIM decided to combine everything best qualities two proposals and created a card that contained standard pads, as Apple offered, and spare pads in the center. Also, the new card received contact pads in the center and a side protrusion on the side, as Nokia proposed:

In principle, everyone is happy with the solution from Motorola and RIM, the card is not long, the contact pads are in place, even with a protrusion! But Apple engineers used their own version in their devices no matter what...

It follows that this is, roughly speaking, a smaller copy of a micro SIM. But by how much is it reduced? Is it possible to cut it, as is the case with SIM->micro SIM?

To do this, let's look at the dimensions of the card and compare it with micro SIM.

• nano-SIM – 12.3x8.8 and thickness 0.67;
• micro-SIM – 15 x 2.5 and thickness 0.81;

It turns out that you need to cut off all the plastic from the micro-SIM and leave only the chip. After that, file the chip with sandpaper so that the card becomes thinner and we get a nano-SIM.

Of course, this is not easy, but sometimes it’s easier than changing, for example, if the number is registered to a company. If you need to adapt a card, contact our service, we will help!

Once upon a time, when you had to use push-button mobile phones, there was only one SIM card format. Therefore, the SIM card could be easily moved from one phone to another - I quickly moved it and immediately started using it. In the era of smartphones, three types of SIM cards appeared at once. Let's talk about them in more detail.

Mini-SIM

Standard Mini-SIM is exactly the SIM card that was used in push-button mobile phones and early smartphones. Today it is much less common, because most modern smartphones This type of SIM card simply does not support. The dimensions are:

• Length: 25mm

• Width: 15 mm

Micro-SIM

Guess which company created micro SIM cards? That's right - it's Apple. The card is much smaller in size. They are as follows:

• Length: 15 mm

• Width: 12 mm

Nano-SIM

After some time, a nano format SIM card was shown. Who became the innovator? Again Apple company. Most modern smartphones support Nano-SIM.

And here are the dimensions of the SIM card:

• Length: 12.3mm

• Width: 8.8 mm

And this is a comparison of SIM cards of three formats:

eSIM

Do you think the decline in SIM cards will continue? It’s unlikely, since eSIM was invented some time ago - this is a special chip that is already built into the smartphone. The user chooses which operator to connect to, and there is no need to go to the office - this is done using the application. If he does not like the tariffs of one operator, he can connect to it through the application of another operator. Convenient, but eSIM is supported in a small number of countries.

Are different sizes bad?

You can say so, since new smartphones mostly support the Nano format. If you have a Mini SIM card, you can either cut it or replace it with the desired size at a communication store - not very convenient.

What if you have Nano-SIM and your smartphone supports Mini-SIM? There are convenient adapters that are sold even in supermarkets. Like these ones:

Today, SIM cards are distributed in the form of a universal SIM card, when the user can choose which SIM card format to use.

What is the difference between a nano SIM card and a micro SIM card?

In fact, only in dimensions - Nano-SIM is somewhat smaller. In addition, formally Nano-SIM should be a little thinner - 0.67 mm versus 0.76 mm for Micro-SIM, however, as far as we know, both formats may have the same thickness. When used, this usually does not cause any problems.

Nano SIM-the card came into use in 2012 with the advent of the first iPhones 5S and iPad tablets 4 mini with Retina, without which the operation of these devices is impossible. It was not so easy to get it back then, and even now such a SIM costs money. Below we will look at ways to turn a regular phone card into a nano SIM card using tools that many people have at home.

A standard SIM card is not much different from a nano SIM card. The chip itself, on which the information is stored, has not changed, which is the most important thing. We will turn a regular SIM into a nano using the following tools:

• caliper (regular or digital) - a device for accurately measuring values, will be needed to measure the difference between cards and mark the marks along which we will cut;
• if you don’t have a caliper, use a ruler, a sheet of paper and a pencil;
• sandpaper or file - for grinding the edges of the cut SIM card in order to reduce the thickness of the original card;
• very sharp scissors.

SIM card sizes:

• nano SIM card: width – 12.3 mm, height – 8.8 mm, thickness – 0.67 mm;
• micro SIMs: width – 14.9 mm, height – 12.03 mm, thickness – 0.81 mm.

Comparing these values, it is clear that the difference in parameters is small, and it is quite possible to eliminate it with the help of scissors.

We take a caliper and set the parameters of the nano SIM card on it one by one: width and length. And we transfer it to a regular SIM card, noting the lines along which we will cut with a pencil, and also do not forget to measure and notice the cut.

If you don’t have a caliper, proceed as follows:

• take a sheet of paper, a ruler, a pencil;
• using a ruler as a measuring device, draw a nano SIM card template on paper;
• cut out this template;
• Place it on top of the micro SIM card and carefully trace the outline of the template with a pencil.

Before cutting the main SIM card, it is recommended to practice on old micro SIM cards, since one careless move can cost you a hopelessly damaged SIM card. When cutting off excess edges, try to touch the chip and contacts as little as possible. Your goal is maximum accuracy in resizing the micro SIM.

If you are not sure that you can cut the card, then Chinese manufacturers have foreseen the need to adapt a micro SIM card into a nano SIM card and have invented a special cutter for removing excess from a regular SIM card, this is what it looks like.

Now the most difficult thing remains: eliminating the difference in the thickness of SIM cards, which is 0.16 mm. Before starting the nano SIM thinning procedure, we recommend wearing a medical mask, since the dust generated during grinding has a rather unpleasant odor and texture. Take sandpaper or a file and carefully, slowly, sand the card on the back of the contacts (where the picture is). If you overdid it in reducing the thickness of the micro SIM card, place a sheet of plain paper under the adapted nano SIM card. Before changing the micro SIM size, it is recommended to watch training videos on the topic of adaptation regular card in nano format. Also, before starting work, it is necessary to keep in mind that the variable micro SIM card

, as well as all the information that is on it, can be lost forever.

Win32.malware.gen - what is it?

Win32.malware.gen is a malicious computer infection. Essentially, a virus is a Trojan horse. It has some similar characteristics to other infections, so it can easily be classified as a Trojan horse. A typical feature that unites all “Trojans” is that it can cause troubles that are associated at the same time with both the operation of a PC or laptop and the personal information of the computer user. What is also very dangerous about Trojan horses is that their presence often goes unnoticed by the user if he does not constantly scan with an antivirus program. And, acting unnoticed, it can cause harm to the computer, disrupt the entire system, merge files, and in every possible way harm the computer and you.

What are Trojan horses?

Trojan horses are a common name for a variety of viruses that enter your computer undetected through some other program or through other routes. The infection got this name because in order to penetrate your computer, they use dishonest and malicious techniques. Often this is the use weaknesses and so-called gaps in the armor of your security program on your computer or through a weak point in operating system generally.

In order to better understand the topic of computer viruses, we advise you to read our article on how viruses become infected. This will help you avoid many problems with your computer in the future.

Generally, vulnerabilities occur when a user does not go through the process of updating programs to protect the computer or uses pirated versions antivirus programs that are a priori weaker than regular ones.

In addition to the fact that Trojan horses use gaps to penetrate the system, they also often penetrate the computer along with programs and applications that you download on the Internet unofficially - from chat rooms, torrents and other unreliable resources. However, even if you don’t download anything and update your licensed protection system on time, the infection can penetrate your computer in the form automatic download a link on an unreliable site that is activated when you visit it. Also, a link to download a malicious program is often sent by mail in the form of spam, and many users unknowingly click on it and download it to their PC or laptop dangerous virus. Also, a friend may simply bring it to you on a flash drive, without even knowing it. That's why you should always run an antivirus scan on any unfamiliar recording device before opening it.

Attackers are very inventive in how they can “slip” you malware, therefore, in order not to download Win32.malware.gen to your computer and not accidentally transfer it to another person.

Why is the infection harmful?

The peculiarity of the malicious work of Trojan horses is that they do not begin to act immediately after downloading. Therefore, the user may not be aware of a virus infection for a very long time if he does not conduct a thorough and timely scan of all computer systems using an antivirus program.

Immediately after the Trojan horse has been downloaded to your computer, it sends a signal via the Internet remote server and receives instructions from him about what information he needs to collect at that moment. In addition, it seems to open the door for other viruses and infections on your computer, so most often the Trojan horse, when checked, turns out to be not the only virus. With him they find about five more people whom he “let” into the system.

It is very dangerous that Win32.malware.gen can bring with it viruses that are not yet familiar to your security system and which it cannot get rid of.

What problems does Win32.malware.gen create?

Despite the fact that the user may not even know that his computer is infected with a dangerous computer virus, a Trojan horse can work unnoticed by the user and in the background greatly harm the normal operation of the computer. This secretive method of operation was invented specifically so that hackers could obtain information from an infected computer and use credit card and payment data, collect personal information from documents, find out passwords for websites and email, as well as confidential information.

In addition, if you store online currency on your computer, such a virus can steal it from you and transfer it to attackers. Sometimes hackers can use infections to monitor everything the user does on the computer using programs such as Keylogger. Criminals thus obtain all information and any data. Even those that you try to protect especially carefully. A Trojan virus can even turn your computer into one of the devices with which hackers carry out their criminal plans.

Additionally, if you have Win32.malware.gen on your computer, then certain information from your computer may already have been stolen or altered. So, you can determine that there are viruses on your computer based on indirect signs. These include:

1. If you notice that there are changes to entries in the computer's registry.
2. If you notice constant problems in the operation of the device, but at the same time everything is fine with the hardware itself.
3. If you can't run some programs or open files. This is especially true for licensed programs.
4. If the programs you use most often suddenly stop responding, constantly crash, and the entries you made there disappear from the program memory.
5. If your antivirus program does not work, it stops normally analyzing the state of the computer.
6. If you cannot access the Internet or the Internet connection is no longer stable and fast. Even if you have a good package, you will not be able to download something due to low speed or upload a video on the hosting.
7. A virus may prevent you from accessing some websites.

If your computer is already infected with this virus, it will greatly ruin your life and can cause real harm. Even if the hacker does not steal your card data or collect personal information, a Trojan horse can still lead to serious disruptions in work, even lead to the death of the computer, or simply erase from the computer all the information that was contained there. Even from drive D.

How to remove Win32.malware.gen?

If, using an antivirus scan, you discover that you have a virus on your computer and it is Win32.malware.gen, then it must be removed correctly and quickly enough in order to minimize the damage it causes. A truly malicious computer attacker.

If you just suspect that you have a Trojan horse on your computer that is corrupting your files and preventing you from working, then check with an antivirus. There are many free, licensed programs that can help you detect malicious files. So if you haven’t installed an antivirus program for yourself, do it as soon as possible.

Most The best way delete a malicious file - do this through the antivirus program with which you found it. The program often offers to disinfect an infected file, but we advise you not to do this, as the treatment may be ineffective. As a result of this, the antivirus program will think that everything is fine on your computer and the file has been disinfected, but in fact there will be a Trojan operating there. So it is better to delete all files that the program has identified as infected.

Remember that if it is a Trojan horse, then there may be a lot of infected files, so delete everything without regret - this the only way completely protect yourself from the virus and minimize the damage.

If you still don't have a good and reliable antivirus program, we advise you to install it as soon as possible. Our article entitled “The best antivirus for Windows 10” will help you decide what to install on your computer, where this topic is discussed in detail.

In the future, you should avoid downloading files from unfamiliar sites. Also, do not click on unfamiliar or suspicious links that are sent to you by mail or email. in social networks. In addition, you need to install a good and reliable licensed antivirus program. And be responsible for carrying out constant checks and promptly treating or deleting files that, in your opinion, antivirus program, are malicious or dangerous.

conclusions

As it became clear from this article, Win32.malware.gen is a very dangerous Trojan horse that can not only harm the operation of your computer, but also harm you, because the virus can leak personal photos and folders, payment data, and mailbox passwords into the hands of ill-wishers and credit cards, your hospital card and so on. Therefore, we advise you to do everything to prevent the virus from entering your computer: install a good, reliable antivirus program and scan for viruses once a week or at least every two weeks. Also, the usual rules of “network hygiene” will not hurt - do not click on suspicious links that are sent to you by mail or on social networks, do not download programs from unverified resources, use torrents less and do not look for dubious information.

If you do encounter such a problem, then, hopefully, thanks to our advice, you quickly deleted the harmful file and your computer did not have time to suffer much from the actions of the Trojan horse.
