How to make a micro sim card from a regular sim card. How to cut a SIM card under Nano-SIM

All tips

Modern gadgets use SIM cards of different sizes. The change first came with the advent of smartphones, where the slot was designed for micro sim, but today the most advanced models of tablets and phones use an even more cropped version. You can cut a SIM card for a new phone yourself, although some mobile operators initially sell SIM cards for special gadgets or the package comes with plastic with divisions, from which you can easily squeeze out a micro or nano version of the card without additional devices.

Cut the sim card with a special device in the cabin

The easiest and most convenient way to cut off any format is to contact a mobile phone salon. Employees can replace the standard plastic with a smaller copy or even make it smaller themselves. Replacement of a SIM card is free of charge, but if you need to cut a SIM card for micro or nano, then most likely you will have to pay extra. At the office, they can show you how to cut a SIM card to a micro or nano size.

Employees of communication salons do not need instructions on how to make a small SIM card out of a large one, as they use a special device that looks like a stapler. The advantage of how to make a mini from a regular model is that you do not need to use a cutting template.

SIM card cutter

As a result, the client receives not only the application from the microsim, but also the adapter for the microsim card from which it was squeezed out.

Thanks to the presence of such an adapter, the card can later be inserted into other models of phones or tablets, because some still use the usual SIM format. If desired, a mobile user can purchase a similar unit for cutting plastic in a mobile phone store. It is worth noting only one shortcoming. If the initial thickness of the sim was more than the standard, you will have to cut off the layer additionally.

How to cut a sim card yourself

You can learn how to make a nano SIM card from a microsim or a regular one with your own hands. But on the first samples, it is advisable to use a few unnecessary old ones so as not to spoil the working SIM. It is easy to convert a microsim to an application, since you need to cut out virtually the entire part, except for the chip. However, if you use only this setting, you can cut too much, so it's better to use the instructions on how to make an application from microsims:

Sizes of SIM card formats

Print out a template to cut out a smaller version from a regular SIM card. In fact, in the photo it looks like a rectangle with sides of 12.3x8.8 mm. If it is not possible to print a full-scale model, use a ruler with small divisions and mark up directly on the plastic. Ultimately, nano-sim should have 0.5 and 1 mm on both sides around the chip, the remaining two sides will be back to back. Don't forget to trim the corner.
Use a sharp cutter or scissors to cut. Cutting plastic is very easy: it is slightly more difficult to cut than cardboard.
Try to insert the cut out SIM card into the gadget. For some devices, this version will be enough.
If the nanocard is too thick and does not fit into the slot (usually this happens if you make a nanosim from a regular SIM card), use a nail file or sandpaper and cut off some plastic from the back side of the chip. The chip must not be touched! The thickness of the SIM card should be 0.67 mm. If you get carried away with sawing and there is too little thickness left, attach a piece of paper to the back for a more secure fit in the slot.

After cutting the nano SIM card, make sure that the SIM card is valid and has not been damaged during the cut. If you know how to cut yourself from nano-sim micro-sim, and use a cutter, you can save the adapter for the transition.

Video review: how to cut a SIM card yourself

At the moment, there are few gadgets left in the modern world that support standard variants of sim cards, micro sim cards have taken their place. For example, in the iPhone 4 and 4S, a micro sim is installed, which appeared in 2003. And in the iPhone 5, 5S, 5C, 6, 6 PLUS, 6S, 6S PLUS, SE, 7, 7 PLUS, there is already a smaller format of sim cards - nano-sim. Therefore, in our article we will raise the question: how to cut it yourself.

The SIM card can be reduced at home, or you can entrust this matter to specialists. You can cut the card yourself at home using improvised means: scissors or a clerical knife, a manicure file or sandpaper and a caliper or a simple ruler. After cutting, the SIM card can still be inserted into a regular phone.

A cropped SIM card can be put into a regular phone, but for this you need to return it to its previous form. To do this, you should contact a specialized online store or the nearest communication salon, they will explain how to insert it, they will offer an adapter for such SIM cards. The best option would be to purchase a whole set, as it includes a set of stickers that will firmly connect the adapter to the antenna so that it does not fall out in any way. If you have not found such stickers anywhere, ordinary adhesive tape will help you.

In addition, the adapter can be ordered from the online store, it includes the adapter itself and a pin that allows you to remove the SIM card tray for iPhone. You can also order adapters for the required format of your SIM card, thanks to it, cards can be installed even in a regular phone. One has only to put the SIM card in the adapter and install it in the mobile device.

How to shorten without damaging the chip

Unlike micro-sim, where the length of the indentation plays an important role, nano-sim is much easier to reduce, since it has practically no plastic edges. Therefore, the chance of damage to the chip is small. But, if you accidentally damaged the chip, and your mobile device does not catch the network, do not panic, contact your operator and they will provide you with a duplicate SIM card of the right size.

What SIM card is in your iPhone?

If you decide to change the card in your phone, make sure that it will be the right size, and if the size does not fit, then learn how to properly cut a micro sim for the iPhone, because the new iPhone models that have been released now only support this type of SIM card like macro-sim as well as nano-sim. Therefore, the owners of such phones will need to either bite off a SIM card in standard formats to the size of a micro-SIM, or under a nano-SIM, or change it to a suitable size, since it is impossible to insert a regular one.

How to cut the SIM yourself

The SIM in a conventional phone is a plastic rectangle with a chip, 25x15 mm in size. Micro sim dimensions are 15x12x0.76mm and nano sim dimensions are 12.3x8.8x0.67mm.

How to safely shrink your SIM at home

In the process of cutting, irreparable things can happen, namely, scissors can come off, you will not cut it off, everything will not go according to plan.

Attention! You must be sure that you know exactly all the nuances of how to trim a sim at home and how to do it yourself. Therefore, in order not to damage your sim, you should practice on old unnecessary sim cards, and only then do this fraud with your main one.

How to properly fit the micro format

Let's figure out how to do it:

First you need to draw a 15x12 mm marking around the chip, along which the card will be cut. After that, take really sharp scissors to keep everything going smoothly, small manicure ones are best for this. On the drawn lines, you need to cut out the excess plastic, after which it remains only to carefully cut off a small corner of the card.

Finally, you need to check the size of the card with the slot in the mobile device. If the card is still large, you need to remove the rest of the unnecessary plastic with a nail file or sandpaper.

We make from a standard sim

The process of converting a standard SIM card to nano is as follows:

You need to cut the SIM card, cut off the lower and upper parts of the SIM card, but before that, remember where the corner is located in order to restore it after. At the end of trimming, the length of the SIM card should be 12.3 mm.
The SIM card will be 8.8 mm wide, for which you need to cut off the excess plastic on the sides.
What and how to do if your SIM card is not included in the slot, does not fit in thickness and which SIM card is suitable? - You will need sandpaper. The maximum thickness of the nano-sim is 0.70 mm, you will need to take a small piece of sandpaper and erase, of course, the operator graphics layer. Erasing plastic does not affect the performance of SIM cards in any way, but before you start doing this, protect your airways with a medical mask or gauze, as dust irritates the mucous membranes and has a pungent odor.

Now let's figure out how to properly make nano-sim from micro-sim. This process is almost the same as reworking from a regular SIM card. Not only is the micro-sim larger than the nano-sim, it also dominates in thickness. The thickness of the microsim card is 0.10-0.15 mm more. Therefore, you will also need sandpaper and a little time.

There is an even easier way to properly crop for nano sim. There is a special tool in communication stores, thanks to which you can easily cut a standard card for micro or nano SIM or for a small fee or even free of charge to the size you need. After that, they will additionally help you insert a SIM card into the slot of your mobile device.

For the first time, scientists thought about creating a miniature SIM card about 20 years ago. But it wasn't until 2003 that the final format of the new map was adopted. The innovation was not only the size, the creators have achieved an expansion of the phone book and improved security of card authentication. Initially, such a tiny SIM card was considered for use in small gadgets, but after the release of the fourth generation iPhone, all SIM card manufacturers began to mass-produce the microsim version.

If you do not want to change your usual and familiar phone number by buying a new starter pack, you can cut the SIM card at home. Of course, you can go to any mobile phone salon or mobile phone repair center, and in a couple of seconds your old regular SIM card will be adjusted to new standards. But it always takes time and money. Do not rush to spend money if you can cut the SIM card yourself without the use of special equipment and experience.

In order to properly cut a SIM card at home, you will need:

Precise ruler;
Well sharpened pencil;
Sharp scissors or clerical knife;
Sandpaper.

What is a sim card made of?

A regular sim card consists of two parts:

SIM chip. This is the metal core of the sim card. This small area is responsible for storing information (call log, phone book, incoming and outgoing messages). Therefore, when cutting a card at home, in no case should the chip be damaged.
plastic plate. It does not perform any function other than framing the chip. She just filled the slot for the old-style sim card. It is this now unnecessary plastic that you will need to cut.

The process of transforming an old sim card

Clearly define cutting lines

Using a fine ruler, mark the cut lines. If the size of the old SIM card is 25x15x0.76 mm, then the smaller version (microsim) will have a size of 15x12x0.76 mm. Around the chip itself, you need to measure and draw a rectangle measuring 15 mm by 12 mm. The chip should remain intact, leaving some plastic around it. There are cards with a chip of a non-standard, increased size. In such cases, it will be necessary to cut almost along the edges of the metal plate. If you do everything very carefully, then you will not damage the SIM card.

Cutting the plastic cover

For such delicate and jewelry work, nail scissors are perfect, as they have sharper and thinner blades. You should carefully cut off all excess plastic around the chip. Take your time, do not make sudden movements. If at least something goes wrong, the micro sim card can be thrown away. It will either stop working at all, or it will “depart” all the time, and the connection will either appear or disappear. A utility knife is sharper and can make cut edges smoother, but it's more dangerous to work with. You also need to cut off a small corner on the same side as on the old SIM card so that it fits into the slot without difficulty.

Fitting

After the operation is successfully completed, you need to try "trying on" the newly made card. To do this, place it in the SIM card slot in your mobile phone. If it fits well and tightly, then try turning on the phone and wait until the phone finds the network of your mobile operator. If everything works, then congratulations.

Necessary correction

If the Simka turned out to be very large, then it's not scary. This is where sandpaper comes in handy. Remove excess plastic with it, because if you try to remove half a millimeter with scissors, you will definitely cut off the excess. And in this case, it will be almost impossible to rehabilitate the SIM card.

As you can see, making a micro sim card at home is real. No need to spend money on this service in the salon. Moreover, you have all the necessary materials for this at home. Remember the safety measures when working with scissors or a clerical knife, and also do not forget the old Russian proverb: measure seven times, cut once.

On older, non-touchscreen phones, and on many touchscreen devices, there was a large SIM card slot. But in modern mobile devices, the slot has become much smaller, and a regular card is no longer suitable.

When changing an old mobile device for a brand new gadget, there is no desire to purchase a new SIM card at all. You can visit the sales office of your operator and change the old SIM card for a new one, while retaining all available funds, tariff and connected options on it. But some users prefer to do everything themselves at home. Therefore, we present step-by-step instructions on how to make a Micro-SIM from a regular SIM card.

From the article you will learn

Why was the standard of SIM cards reduced?

What are the manufacturers of mobile devices proud of in the first place? Of course, its compactness and relative lightness. And to perform these tasks, you need to reduce the allocated spaces, including for the SIM card slot.

A lot of space was used for the old standard of SIM cards, and if the size of the card is significantly reduced, then the space for the slot will be allocated an order of magnitude less, many manufacturers agreed with this. And now, in order for the new device to work from the selected telecom operator, you either need to purchase a new SIM card size, or cut the existing one to the desired slot size.

What standards are used in the latest gadgets?

In addition to the usual size, familiar to many owners of old phones, manufacturers use Mini, Micro and Nano-sim slots.

Micro SIM card size is required for 4/4s generation Apple devices, Nokia Lumia, Sony, Samsung and other manufacturers. But the nano size will be needed for the iPhone 5/5s series and newer, as well as on new devices from different manufacturers running the popular Android OS.

We cut the SIM card under Micro-SIM

When buying a device, not all sellers warn about the need to install a Micro-SIM card in a new mobile gadget. And this sometimes discourages the user when he tries to insert an old SIM card into a slot that is completely inappropriate for it. Or it's just a pity to part with your tariff and the list of available services that are directly related to an existing card.

The standard card size is 25mm x 15mm x 0.75mm. It is a durable plastic with a chip applied, it is he who is the main component.

If the chip is even slightly damaged, then it will be impossible to use the mobile operator's communications. It is this condition that should be the main one when fitting a standard SIM card to Micro-Sim forms. Pruning must be done very carefully.

Required Tools

So that at home you can independently adjust the SIM card to the desired parameters, stock up on the following set of tools:

Manicure sharp scissors;
Sharpened pencil or ballpoint pen;
A ruler marked in millimeters.

The size we need will be 15 mm. X 12 mm. X 0.75 mm.

Trimming process

We put the card on a flat surface so that the chip is outside;
We turn it with the cut side up, so that the corner looks to the left;
From the side of 15 mm (on the right), set aside 1.5 mm towards the center, cut off the excess;
On the underside, 25 mm long, set aside 1 mm also towards the center, draw a line and cut along it;
We need the right side of the card to be 12mm long. To do this, draw a line from the top side to the center of 2 mm. Since we have already cut off earlier, we will get exactly 12 mm, that is, the desired parameter. But at the same time, the corner will be cut off. There is no need to worry about this, since it will be restored later;
Now we need to align the desired length, that is, 15 mm: starting from the right side, we measure the indicated distance, remove the excess with scissors. This is not yet a SIM card, but only its preparation;
Now you need to round off all the corners a little, because that's what the old Sim looked like;
The final touch is cutting the corner. It is necessarily present on all cards - we need to draw an equilateral triangle with sides of 2 mm. Attach a ruler, measure 2 mm down and to the right, and then you can cut.

Trying to insert the resulting sample

If everything is done correctly, then the SIM card should exactly enter the slot installed for it. If it is a bit too big, then cut off the side that is larger.

The network should be found, and if it is, then try calling someone. In case of failure or damage to the chip, you will have to contact the operator to restore your SIM card.

We independently reduce the SIM card to the desired size

So the time has passed for everyone's favorite "bricks" and sliders. Their mesmerizing games and ringtones have remained only in our hearts.

The time has come for new innovations and cell phones have acquired completely different functions and, of course, appearance. Nowadays, in many gadgets, it is possible to use only micro-SIM (a reduced standard SIM card) or nano-SIM cards.

Many are perplexed due to the fact that their old SIM card from a shabby and small phone is completely unsuitable for a modern gadget.

Many people try to squeeze their favorite SIM card into the wrong slot, call their advanced children or friends with the same question - I bought a new phone, I was very pleased, but my SIM card does not fit it at all!

He is given advice to immediately change the SIM card, but do not rush to do this, because today we will talk about the micro-SIM card. Namely: how to make it from a regular SIM card and what to do if nothing comes of it.

Of course, first you need to realize that nothing will happen to our SIM card and it will serve you faithfully for a long time if you follow written instructions. So, finally, we start learning how to turn an old SIM card with standard sizes into a micro SIM card with our own hands.

Let's start with the fact that the dimensions of the micro-SIM card must be within 15x12 mm. You can cut a regular SIM card to such sizes as follows.

What do we need for this difficult and risky business? And we will need:

sharp manicure scissors;
well-sharpened pencil;
ruler;
Of course, patience - here, probably, this will be the most important thing.

Now let's go directly to the so-called "fitting" a standard SIM card for micro.

So, put our sim card top with a chip on a flat and dry surface table. After this action, we need the most common ruler (take the one on which all the millimeter markings are clearly visible, because in this case we will need them).

We carry out "from above"(we will consider the top as the place where there is no cut corner) SIM card line, 12 mm long, stepping back from the edge of about 1.4 mm. (try to keep the millimeter exactly). Now, from the edge of the resulting line, we measure down (to the place where we have a cut corner) a similar line, only 15 mm long. (at the same time, stepping back from the edge of 1.8 mm).

We connect the resulting dashes into a rectangle - in the end, we should get it with dimensions of 15mm. horizontally and 12 mm. vertically. (it is necessary to strictly ensure that the chip is not affected. If this still happens, then in no case do not touch it when performing the circumcision, it is better to step aside a little).

Then gently cut out this rectangle. scissors. It remains only to cut off the unnecessary corner (you can attach the unnecessary cut off part to the new micro-sim and cut off the unnecessary part along it, drawing a line).

Now we need to check if our new SIM card is included in the smartphone. If some of its parts protrude and do not allow it to lie flat in the slot, then we will use sandpaper or an ordinary nail file, grinding off the interfering sections of the micro-SIM card.

You can also use a simpler method, but for this we need a reliable friend with an already existing micro-sim card! In this case, it is only necessary to extract the already existing micro-SIM and “impose” it on our standard SIM card.

Then, with a sharpened pencil, we trace the outline of the micro-SIM and, having removed it, we cut the SIM card just as carefully with the help of sharp scissors or a clerical knife. By the way, cut neatly, for the "unnecessary part" can be used in the future (by simply "inserting" the micro-sim card into its "old shell").

It is also necessary to remember that if the size of our SIM card is a little larger than necessary, then this can always be corrected.

If the micro-SIM card is made smaller, then it is simply will be spoiled and you can only throw it away (therefore, it is better to cut a standard SIM card for micro with a margin, which, in case of uselessness, you can always either cut or grind off with the same sandpaper or nail file).

If you still failed to turn a regular SIM card into a micro-SIM, or you just don’t really want to bother with it, don’t be discouraged! You can always replace a regular SIM card with a micro-SIM at any office of your operator by presenting your passport or ask the salon staff to cut out the necessary one from the old SIM card.

And there are times when we need, on the contrary, from a micro-sim card make a standard. For such situations, there is a special adapter for a micro-SIM card, which can be bought at any communication store. Then your SIM card will become universal and will fit any device!

We hope that our advice helped you dispel your doubts that it is impossible to make a micro SIM card from a standard SIM card! Follow the algorithm exactly, try to observe all sizes and you will certainly succeed!
