Cut the SIM card for a micro megaphone. How to cut a SIM card to Micro or Nano? Bringing a cropped SIM card to perfect condition

Currently, on many modern gadgets, you can only use a smaller version of a standard SIM card - micro sim. This is due to the attempts of manufacturers of technology to save internal space in the device in order to place other elements more compactly and make our phones and tablets smaller, thinner, lighter and ultimately cheaper to manufacture than their predecessors.

Having bought new phone or a tablet (for example, Samsung, HTC, iPhone or iPad), you may find that the standard SIM card does not fit it, and in order to continue using your usual SIM card after buying a new device, you can cut it off. The main chip remains in place, only the dimensions of the plastic base are reduced. Make micro sim out regular sim card at home it’s easy, all you need is sharp nail scissors, a sharpened pencil, a ruler, sandpaper (or a nail file) and a little patience.

An ordinary SIM card is a plastic rectangle with a chip, having parameters of 25x15 mm. The dimensions of the micro SIM card must be 15x12 mm. You can cut a regular SIM card to the desired size as follows:

If the SIM card after resizing is larger than necessary, it can always be corrected, if the size is significantly smaller, the SIM card will become unusable and you will have to change it to a new one.

If you are afraid of damaging your SIM card or just too lazy to mess around, you can replace the standard SIM card with a card of the right size at any Beeline office. Upon presentation of a passport, the subscriber will be issued a new SIM card, or trimmed to a micro sim format old sim card, an apparatus that looks like a stapler. It will take a minimum of time.

The reverse situation is also possible - the use of a micro SIM card in devices with standard slots. To do this, you will need a special adapter for micro SIM cards, which can be bought at any communication store. Thus, your micro sim card will become universal for most devices.

Modern smartphones and tablets are supposed to use smaller SIM cards, the so-called micro-sim. This is due to the fact that manufacturers are trying to reduce the thickness mobile devices. You can reduce the standard SIM card in the cabin by paying money for it. But you can cut a SIM card for a microsim at home using a special template.

The latest smartphones often use smaller micro-SIM cards. There are many ways to reduce a standard chip.

Order a card of the required size in the salon. This is a great solution to the problem, but you still need to get to the salon.
When buying a brand new smartphone, immediately ask the seller to cut the chip, but you need to remember that this is a paid service and its cost ranges from 200 rubles or more.
You can buy a tool for trimming sim cards yourself, but it can cost up to 1000 rubles. Trimming just one card is not worth it.

You can cut the card with your own hands, using improvised tools and materials. This must be done carefully so as not to damage the circuit itself.

The template is printed on A4 format, scaled 1:1. If the template is planned to be used more than once, then it is made of thick paper, cardboard or even a special film.

Required Tools

Before starting work, prepare necessary tools and materials.

Sharp scissors or clerical knife;
A ruler, preferably a metal one;
A simple pencil or pen, the pencil should be well sharpened;
A sheet of paper for making a template;
Sandpaper or nail file.

It is important to prepare sharp scissors, such as nail scissors. Scissors with thin blades chew plastic less.

Instead of a template for trimming, you can use a SIM card of the desired size. It is simply placed on a standard chip and circled. Then the excess plastic is cut off.

Trimming process

You need to cut the card with great care, trying not to damage the chip. Perform work in the following sequence:

They print out a template on the printer, take a regular SIM card, put it on a sheet so that the lines coincide with the future microsim. Carefully trace the map with a pencil.
The sheet is turned over and the SIM card is fixed on it with adhesive tape, combining with the indicated contours.
Turn the sheet back and carefully draw along the lines with a clerical knife along the ruler. It is important not to rush and work with a knife carefully. Instead of a ruler and a knife, you can use sharp scissors, the effect is the same.
After that, they remove the card from the sheet and trim the plastic around the edges with nail scissors.
The final step is polishing the card. To do this, use sandpaper or a nail file.

After that, the card is ready for use. If it does not fit well in the slot, then it is slightly trimmed with sandpaper.

It is worth remembering that if the chip is damaged, it will not work and will have to be replaced.

Cut the SIM with a special cutter

Cutting a SIM card with a special cutter is very simple. This device looks like a stapler, only slightly larger. This cutter is made of metal. Depending on the manufacturer, the design may differ slightly, but the principle of operation of the devices is the same. The standard chip is placed in the groove of the lower part of the device and pressed with the upper part.

When cutting with a cutter, the possibility of damage to the microcircuit is almost excluded. But we must not forget that too cheap devices do not cut cards well. At best, they have to be finished with sandpaper, and at worst, they have to be changed.

To cut a standard SIM card to a microsim standard on your own, you do not have to pay money. You can do this yourself with a clerical knife or scissors.

The creators of modern mobile devices are striving to make them smaller and thinner, introducing new features due to the development of technology. All this leads to a change in generally accepted standards. Phone owners are faced with these manifestations of progress all the time - with almost every new generation of phones, a new type charger, and in recent years, instead of standard SIM cards, which are available at any sales office of mobile operators, micro and even nano SIM cards began to appear.

A small SIM card saves usable space in mobile phone, and phone owners latest models, for example, Samsung and Apple are faced with the fact that a standard SIM card does not fit the device. At the same time, all the functionality of the card will be preserved, only its size changes: 12x15 mm for micro versus 15x25 mm for the standard one. In this article, we will tell you what to do if the SIM card does not fit into a modern phone.

How to cut a SIM card under Micro SIM?

Owners of new phones often face the problem of cutting a SIM card after purchasing a new product: not all sellers warn that a standard card is not suitable for certain models that require a micro-SIM card. In this case, you can trim the SIM card yourself.

In fact, it is not as difficult as it might seem. In order to make a micro sim from a regular sim card and cut off the excess yourself, you will need:

pencil
ruler
sharp scissors
sandpaper

To simplify the process, we recommend using the micro SIM card template - download and print it. After that, stick your SIM card with adhesive tape on a printed sheet of paper over the selected template. Then, using a ruler and a pencil or pen, draw the dimensions of the future micro-sim on the SIM card.

Carefully cut it out with sharp scissors or a utility knife and trim the edges with fine sandpaper. Additionally, you will need to slightly undermine the thickness of the card from the side of the logo with sandpaper. That's it, the Micro SIM card is ready, and it can be used for its intended purpose.

If, after cutting, you want to use your micro SIM card in a phone with a standard slot, you don’t have to change it, just purchase an adapter for micro SIM cards in an electronics store.

Or you can measure the desired dimensions with a ruler and manually cut off the excess plastic. When marking, put the SIM card with the chip up so that the beveled edge is at the top right. To the right and left of the edge of the SIM card, measure and cut off 1.5 mm, from the bottom - 2 mm and from the top - 8 mm.

Be careful not to damage the golden chip on your card. Now measure where to cut the beveled corner: from the right top corner 2 mm down and the same amount to the left, connect the resulting points with a ruler and a pencil, then carefully cut. Slightly round the edges of the SIM card with scissors.

Sometimes it's easier to change than to cut

All you need to do is gently squeeze the SIM card of the desired format out of the plastic frame. The only inconvenience when replacing a SIM card is that the numbers from it will need to be saved to the phone.

Also, there are special devices in communication stores that allow you to quickly and accurately cut any SIM card to the required slot size on a mobile device, both micro and nano. This service is provided free of charge, and the SIM card is cut to the required parameters in a couple of minutes.

Despite the fact that the idea of creating a mini-SIM appeared more than 20 years ago, the final version of the new card was approved only in 2003. Innovations have affected not only its size, but also functions. So, the creators managed not only to expand phone book, but also to achieve a significant improvement in authentication security. Today, such cards are massively used in small gadgets. But most people who are forced to change their phone are often unwilling to change their usual and well-known number. Therefore, many of them are interested, under the micro-sim.

What are the main parts of a SIM card?

In order to better understand how to properly cut a SIM card, you need to have at least a minimal idea of what it consists of. An ordinary SIM card consists of two parts - a SIM chip and a plastic plate. The first is a metal core on which all information is stored. For those who have a regular SIM card, it is very important not to damage this chip when cutting it. The second serves as a decorative frame for the chip and does not carry any functional load. It is she who is considered the very part that the mini-sim card does not need.

How to cut this unnecessary plastic and what is needed for this? First of all, you should make sure that everything you need is at hand. So, to cut a sim card, you will definitely need:

sandpaper;
stationery knife;
pencil;
precise ruler.

In case of absence, it can be replaced with sharp scissors.

Existing SIM card formats

To date, in addition to the standard SIM card, mini-, micro- and nano-SIMs are actively used. All of them are derived from the first SIM card, the dimensions of which were comparable to those of bank cards. One of the main reasons that prompted phone manufacturers to reduce the size of a SIM card is the saving of free space inside the device itself. Therefore, using the example of reducing the subscriber identifier module, one can get a clear idea of the stages of evolution of mobile devices. The use of micro- and nano-sim cards allows you to free up additional space for a more compact arrangement of elements.

Traditional mini-SIMs are suitable for most phones released before 2011. A micro-SIM card can be inserted into more modern models, while a nano-SIM is designed exclusively for the iPhone 5/5s.

Clear cut line definition

Before cutting a SIM card for a micro-sim, it is necessary to mark the cutting lines. This can be done with a straight line. A 15x12 mm rectangle is marked and drawn around the chip. In order not to accidentally damage the chip, a small area of plastic is left around it. Those who have a non-standard enlarged card will have to cut in close proximity to the edge of the metal plate. In this case, you must be extremely careful not to spoil the SIM card.

Removing the plastic cover

Before you cut a SIM for a micro-SIM, you should get nail scissors with sharp thin blades. They are ideal for trimming the plastic framing the chip. You need to act slowly and without making sudden movements. Otherwise, there is a risk of damaging the card. In the process of trimming the plastic casing, it is necessary to cut off a small corner on the same side as on the previous card. This is necessary so that the new SIM card can easily fit into the slot.

Fitting and necessary correction

After the successful completion of all the above manipulations, it is necessary to “try on” the received card. To do this, it must be placed in the slot of your phone. After making sure that the SIM is firmly in place, you can try to turn on the phone and wait until it catches the mobile operator's network.

If it turned out that the SIM card is somewhat too big and therefore does not fit in the slot, it can be slightly corrected with sandpaper. Attempts to cut off half a millimeter of excess plastic with scissors or a clerical knife can lead to the fact that the card will simply have to be thrown away, since it is unrealistic to rehabilitate a damaged SIM card.

Alternative methods for modifying an old map

For those who are interested in how to cut a SIM card for a micro-sim, but do not dare to do it on their own, we can offer another option. To do this, you just need to contact the operator providing services cellular communication asking for a replacement card.

To do this, you will need to drive to the office of the company and, presenting your passport, pick up new sim card in exchange for the old one. The new card is a standard mini-SIM, which, if necessary, can be adapted to micro. To do this, simply squeeze out a smaller card by pressing firmly on the perforation applied along the edges of the micro-SIM card.

In case of replacing the old SIM card with new map preserved not only tariff plan, but also all your subscriptions. The old card will be deactivated by the operator within 24 hours.

They bought a new phone or simply decided to change the gadget, and its SIM slot turned out to be of a different format. Now you need to cut the SIM card under microsim . This procedure is provided in any mobile phone salon. You can adjust the SIM card to the desired size yourself. Let's talk about the last option in more detail.

Instruction

The SIM card is assembled from two components. Contacts in the form of a chip are applied to the plastic base. Each pin is responsible for a specific function: power, information storage, data input / output, grounding. It is enough to damage any of them - and the card becomes inoperative. This risk is especially relevant for old-style SIM cards with a large chip.

Incorrect trimming of the plastic itself will immediately affect the performance of the SIM. After manipulations with it, the card may not fit in the slot or, conversely, hang freely in the slot and not fit snugly to the contacts, or move in the slot, and one contact on the chip will be connected to an inappropriate contact in the phone.

Decided to cut yourself? Then stock up on tools:

sandpaper or nail file from a manicure set;
stationery knife or sharp scissors;
ruler;
pen or pencil.

First step. Measure on the old sim card its future dimensions: 15 mm in width and 12 mm in length. Ideally, a narrow strip of plastic should remain between the chip and the cut line.

Second step - trimming the SIM along the marked lines. The main thing in this matter is accuracy so as not to damage the contacts. It is best to cut in one motion along the entire length, so there are no notches on the plastic. Don't forget to cut off the upper left corner if you look at the SIM card from the side of the chip.

Third step - Fitting the SIM card to the slot. This is where the saw will come into play. If the SIM card does not fit in the slot, instead of additional cuts, file it.

Remember! When failed attempt cut the SIM card yourself, you need to contact the salon to replace it mobile operator. The replacement service is free of charge, however you will be asked to top up your account. The amount depends on the operator.

Sample

To correctly cut the card (with less risk) under the micro-Sim , download a stencil template or make your own.

How to make a template at home :

Take a sheet of paper, attach your mini-SIM card to it and circle it so that the beveled corner is at the bottom right.
Step back from the left edge along the width of 2 (1.85) mm, from the right 11 mm, from the top and bottom edges along the length of 1.4 mm and draw lines. You will get a rectangle measuring 15 by 12 mm.
To form a beveled corner, step back from the original top line of 3.9 mm or from the new 2.5 mm, put a point. From the left initial edge, measure 14 mm and put a dot. Connect two points with a line.

The template is ready, cut it out, attach it to the SIM card, circle and cut the card.

Popular phones under microsim

Initially, all phones were produced with slots for mini-SIM cards. But time imposed tough conditions on devices, and engineers began to save space, including for SIM. The first phone that set the micro-SIM format was the iPhone 4/4s. Followed by by Apple on the new standard phones switched first Nokia Lumia, and then Samsung pulled up, starting with the Galaxy S III series and HTC in the One series.
