To deal with this issue, you need to understand that now modern smartphones use special so-called microsim cards. Therefore, many owners, having brought the phone home and trying to insert a regular standard SIM card into it, do not understand why the phone does not work and are tormented by the question of how to insert a SIM card into the Samsung galaxy s3. To solve this problem, you absolutely do not need to have any special technical knowledge, you just need to be patient, with a small instruction and a sharp clerical knife. Before starting work, it is necessary to determine the old or new sample of the electronic chip on the SIM card, since if the SIM card of the owner of the phone has an old chip, then the manipulation described below will not help.

It is very easy to determine this, if the SIM card was purchased after 2010, then it is quite possible to make a microsimcard out of it. Before you start cutting off unnecessary edges of the map, you should turn to the Internet. To do this, you need to study how the micro SIM card should look - but usually it is just 1 millimeter larger than the chip on each side. Using a pencil and a ruler on the SIM card, you need to step back from the chip about 1 millimeter and draw a kind of rectangle, with one corner cut off. After the card has been lined, you need to take scissors or a clerical knife and cut off the upper part of the future microsim card, this must be done very carefully so as not to accidentally damage the chip on the card. Also, special attention should be paid to the fact that the cut line should be perfectly even.

Since any negligence can lead to damage to the SIM card. Then, you need to cut off the right side of the card, usually it is the largest and the card number is located on it. All cut lines must be parallel to the internal chip located on the SIM card. Then the left part of the sim card is cut off - this is the thinnest part of the segment, so it is better to use a clerical knife here, and not scissors. By the way, in no case should you use nail scissors with rounded edges for work, as this will lead to the fact that the cut lines will not be even, and as a result, the SIM card will not work. The very last step is to cut off the bottom line under the chip and make a cut on it.

First you need to cut off the bottom of the sim card - the result should be a rectangle smaller than the sim card once was. Now you need to cut off the lower right corner, for this it is best to use a protractor and mark an angle of approximately 45 degrees with a pencil, and then cut it off with a clerical knife and a ruler. In principle, all work is completed. Now it remains only to insert the SIM card into the phone, for this you just need to remove back panel cover at Samsung smartphone galaxy siii and carefully insert the resulting sim card into the hole for microsim cards. Then you need to turn on the phone.

This method does not give a full guarantee that after the manipulations the purchased phone will work, besides, no one can give a 100% guarantee that cutting the SIM card will not break the phone. So, how to insert a sim card in Samsung galaxy s3? So that this does not lead to a breakdown of the device? To do this, just go to any salon cellular communication, where for a nominal fee they will cut your existing SIM card to the desired size. It is best to do this immediately when buying a phone - in this case, any malfunction in the phone. Caused by trimming the SIM card can be attributed to the fault of the seller

But, the best thing is not to suffer and not to spend extra money, but completely free in the salon mobile operator, whose SIM card is used by the lucky owner of a Samsung galaxy s3 smartphone, order a duplicate SIM card in micro size. This procedure is completely free and does not require any additional and time costs. All that is necessary for the owner of the phone is to write a statement in which it is necessary to indicate that a micro sim card is needed. And also when buying a new card, for example, if the phone was bought as a gift, you can immediately order a set of cards, which will include a micro sim and a sim of a standard size for ordinary phones.

When developing samsung galaxy S6, the Korean manufacturer decided to abandon the metal and leather look plastic in favor of an aluminum frame and a glass back panel. As a result, the smartphone turned out to be quite attractive and began to really look like a flagship device, and not like a cheap Chinese something. Since the body of the phone turned out to be monolithic, the engineers had to move some elements that could be accessed in previous flagships simply by removing the cover. So, the SIM card slot moved to the side panel under the power button and got a tray. Unfortunately, not everyone who wants to buy the Samsung Galaxy S6 knows about this move. Therefore, we devoted this short article to the question: how to insert a SIM card into the Samsung Galaxy S6.

How to insert a SIM card into a device

The SIM holder can be found on the right side of the mobile device through a small hole. To insert a SIM into it, you must do the following:

1. Find an ejector, commonly referred to as a paper clip. It is usually included as standard with a smartphone.
2. Insert it into the hole and slightly push it inward.

   Inserting the ejector into the hole of the SIM holder: try to do it as evenly as possible

3. Carefully pry up and remove the holder.
4. Place a nanoSIM SIM card in it. It is advisable to use a card issued by the operator, and not cut off on your own, so that there are no conflicts between it and the smartphone in the process.

   Correct placement of nanoSIM in the holder

5. Place the holder in the compartment so that the hole in the "ear" of the tray is near the power button.

How to remove the SIM card from the device

1. Insert the ejector into the hole in the tray and push it inward.
2. Carefully remove the tray with the SIM card and take it out.

You will need a suitable SIM card for the Galaxy S8 and S8+ and use it correctly.

This guide will tell you what size is applicable, how to insert and change the SIM card, and how to use two SIM cards in Dual SIM versions.

What is the correct SIM card size?

To make phone calls or use mobile data, you will need a SIM card (Subscriber Identity Module), which can be obtained from any telecom operator (MegaFon, MTS, Beeline, Tele2, etc.).

Technically, for mobile phones There are 4 different card sizes:

1. Full size SIM card. Often referred to as 1FF (1st form factor). This is a "giant" size: 85.60 mm × 53.98 mm × 0.76 mm. You probably won't be able to find it on the market, and no Android phone has used this size.
2. Mini-SIM (2FF). Commonly referred to as a "large", "normal" or "standard" SIM in some countries. Most carriers and phone manufacturers phased out their production a few years ago.
3. Micro-SIM (3FF). Still the most popular size for smartphones. Most mid-range and budget smartphones use this card. In some regions, it is called a "small" SIM card.
4. Nano-SIM (4FF). This is the "smallest » map available today for smartphone. For most flagship smartphones, this is required.

The Galaxy S8 and Galaxy S8+ use a Nano-SIM card.

If you just bought a new flagship from Samsung, and before that you used another phone, then you may have already used a nano SIM card in it.

For example, some popular phones using nano-SIM: Galaxy S7 (edge), Galaxy Note 5 and 7, Galaxy S6 (edge, edge +), iPhone 7 (7+), iPhone 6S (6S+), iPhone 6 (6+ ), iPhone 5, Moto X (including all generations) and many others. If you had/have any of these phones, the SIM card will work for the Galaxy S8 (S8+) as well.

You can always get a Nano-SIM from your carrier (preferably), but you can cut the Micro-SIM card yourself to the desired size, for example, using a special cutter or a clerical knife.

What is slot 2 in the SIM tray?

As shown in the figure below, the tray has two slots, regardless of the region.

Slot 1 is always dedicated to the SIM card.

However, slot 2, which is larger, may be used differently depending on your region and model.

Slot 2 is used for Micro SD memory cards and only in the Dual SIM version (model availability depends on your region) you can insert a second nano-SIM card into it.

How to insert a SIM card?

To insert a SIM card into Galaxy S8 and S8+, you need to follow the next 5 steps as shown in the picture below.

Step 0: Turn off your phone.

Step 1: Insert the special tool (supplied) into the hole on the tray and push it all the way down to loosen the tray.

Step 2: Pull out the tray carefully.

Step 3: Place the SIM card in slot 1 with the metal parts facing down.

Step 4: Fasten it.

Step 5: Insert the tray back.

Step 5/1: Turn on your phone.

How to remove or replace a SIM card?

You can remove or replace the SIM card, by analogy with the instructions discussed above.

How to use two SIM cards in the Dual SIM version?

For the dual SIM version of the Galaxy S8 or S8+, you are allowed to use 2 SIM cards at once.

Please note that there are some restrictions:

• This only works in Dual SIM version.
• You cannot use a micro SD card when using two SIM cards at the same time.
• They technically have dual standby, not two active. But in some mobile networks where 2G is being phased out, both SIMs can connect to 3G/4G networks and both can work simultaneously as active dual SIM phones. Whether it can work like this depends on your carrier's network.

In the dual-sim version, management is carried out in the "Settings - SIM-card manager" menu. You must specify which SIM is for mobile data (although both can connect to 3G / 4G networks) and which will be the default for calls and messages. These settings can be changed at any time.

Replacing the Samsung Galaxy S4 SIM card is a task that seems difficult and overwhelming, given the new MicroSIM standard used in phones of this model. Users who are used to solving communication problems by rearranging the SIM card, as well as retrogrades who change the operator or phone number by purchasing a completely different card, are confused when faced with this problem. We will teach you how to remove and insert a Samsung C4 SIM card at home.

Instruction

This instruction consists of five steps. You will need a special plastic spatula, long nails or some kind of comfortable and soft thin object with which you can pry some details.

Step 1: Pry off the left edge of the Samsung C4 back cover with your fingernail or spatula. A special connector for this is located at the level of the main camera and the power control button.

Step 2: Insert a plastic spatula into the gap that has now formed and move it from left to right, opening the latches in sequence (these latches are located around the entire perimeter of the inside of the phone case). At the moment when the back cover has completely moved away from the case, remove it and set it aside.

Step 3: After removing the back cover, be sure to remove the memory card from a special slot located directly under the main camera of the device:

• Gently press down on the edge of the memory card until you hear a click.
• Remove the spatula or finger from the card - a click preceded the automatic ejection of the memory card with its locking tray.
• Once this has happened, remove the memory card and carefully place it in a place where it will not get lost.
• When assembling the Samsung S4, insert it in reverse order.

Step 4: Pry off the phone's battery, remove it and set it aside.

Step 5: To remove the Samsung Galaxy S4 SIM card, push it inward, as you did with a memory card:

1. You need to press it gently and until a click is familiar to us.
2. When you hear a click, release the holder so that it can automatically pull the tray out of the slot.
3. When the SIM card tray has appeared completely, it's time to remove the SIM card from it.
4. Now you can insert another card into the slot and put the phone back together.

As you can see, MicroSIM is no more difficult to handle than the most ordinary SIM - there was nothing to be afraid of!

In this article, we will tell you how to correctly insert a SIM card into your phone yourself. New modern models come out with convenient slots into which cards of the right size are inserted without problems.

Yes, and all popular mobile operators produce original constructors - SIM cards of three popular sizes: nano, micro and standard.

SIM cards are the identification module of the subscriber of the telecom operator. Several decades have passed since their launch and before the start of mass sales, and during this time their shape and size have improved. This process was forced. First, smartphones appeared on mobile markets, and there was simply not enough space under the back cover for details. Technology has improved, user demands have increased, batteries are getting bigger, phones are thinner, and there is less space.

This evolution of cards has allowed them to be reduced by almost half, and modern retractable slots have noticeably freed up space for other details.

Let's look at what types of sims are, what is their peculiarity, and how to insert a sim:

• Full-size (the presence of which many did not even know) - the largest in the line, along the perimeter as bank card. Appeared in 1991 with the first wave of popularity of cellular communications among ordinary residents. It is not used in modern phones, sometimes you can find cars with similar "innovations" a la the 90s.
• Mini-SIM - still used for devices released from the period of the 2000s to the early 2010s, supports 2G and 3G.
• Micro-SIM - appeared in 2003, but is currently considered the most used generation of communication modules. Supported by all manufacturers of modern gadgets with 3G and LTE.
• The smallest is the Nano-SIM, which looks just like its predecessor, minus the plastic edges. Appeared five years ago, and is used in all models of the Apple brand and some other premium segment manufacturers.

All types of SIM cards are inserted in the same way - into the designated slots in a smartphone or tablet. It is impossible to say exactly where the stand is located, as the manufacturers reserve the right to place them anywhere, according to their design concept. Sometimes on new phones they stick a sticker with step by step instructions, it can also be found in the User's Guide.

SIM card installation

Traditionally, manufacturers place card holders on the right side of the case (if the cover is not removable), or directly under the battery if it is removed. The following instructions are suitable for owners of the latter type of gadgets:

1. Check if your phone is turned off.
2. Detach the back panel.
3. Find a small indentation between the case and the battery.
4. Remove battery.
5. There you will see slots for SIM cards. They are of different types: separate and two-story. The side to be held up when inserting will be displayed next to the holder. As a rule, it is inserted with gold contacts down.
6. Insert the battery carefully back. Make sure it fits snugly.
7. Return the cover to the characteristic clicks. They will mean that the lid has fallen into place.

In the video you can see how to deal with modern models that do not have a cover removed:

And here is another video with a useful life hack:

Settings

Modern smartphones and SIM cards do not need manual connection. When first launched on a new device from mobile operator the package will come free settings for all types of cellular services.

For two-term mobile devices, management can give a beginner a little difficulty. You can select a SIM for certain actions by default, or choose your own for every call and message.

Will a regular sim card fit in a micro sim slot?

You can cut the card of normal sizes to micro-sim dimensions if the card is old. However, it is much easier and safer to contact service center, where you will be given a new sim in the form of a transformer - all popular sizes.

If the module urgently needs to be replaced with a smaller one, you can cut it manually with ordinary sharp scissors.

What to do with an unsuccessfully cut sim card

However, such experiments do not always end successfully. If the SIM was incorrectly cut and damaged, you must contact the customer service points of your mobile operator. Replacing the card with another sim while maintaining the balance, tariff plan and, directly, the numbers do not take long.

It is not recommended to insert a sim that has mechanical damage.

SIM card malfunctions

Users guess about their malfunction when the OS does not see the module and does not designate it with the corresponding icon. The reasons may be:

• The SIM has expired and is not intended for further use.
• It has mechanical damage - scratches, chips and breaks.
• Unsuccessful pruning. We mentioned it above.
• The firmware of the phone is tailored for a specific buyer.
• Slot problems.
• Crashes in operating system and software.
• Contacts were damaged during installation.
• Dirt got on the card holder.

In most cases, the card needs to be replaced, or the phone needs to be sent to the master for diagnostics, as these can be both hardware and system problems.

Conclusion

Mobile communication and the Internet, throughout the day, are available thanks to smartphones and small card modules produced by cellular communication providers. That is why they need to be treated with care, monitor their condition and serviceability. The more gadgets come out, the easier it becomes to use SIM - their size is reduced, and the possibilities are growing. We hope you found this article useful and provided you with easy-to-follow instructions on how to handle them in different situations.
