Instructions for correctly installing a SIM card in any phone. Installing a SIM card on a Samsung Galaxy S7 How to insert a SIM card into an old Samsung

To understand this issue, you need to understand that modern smartphones now 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 don’t need to have any special technical knowledge at all, you just need to be patient, a little instructions and a sharp utility knife. Before starting work, it is necessary to determine the old or new type of 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.

This is very easy to determine; if the SIM card was purchased after 2010, then it is quite possible to make a microsimcard from it. Before you start cutting off unnecessary edges of the card, you should turn to the Internet. To do this, you need to study what a micro SIM card should look like - 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 about 1 millimeter from the chip and draw a kind of rectangle, with one corner cut off. After the card has been lined, you need to take scissors or a stationery knife and cut off the top 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 straight.

Since any carelessness 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 cutting lines must be parallel to the internal chip located on the SIM card. Then the left side of the SIM card is cut off - this is the thinnest part of the cut, so here it is better to use a stationery knife rather than scissors. By the way, in no case should you use nail scissors with rounded edges for work, as this will lead to the cutting lines being uneven 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 bevel on it.

First you need to cut off the bottom part 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 use a utility knife and a ruler to cut it off. In principle, all work is completed. Now all that remains is to insert the SIM card into the phone; to do this, you just need to remove the back panel cover of the Samsung galaxy sIII smartphone 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 provide a complete guarantee that after the manipulations performed, the purchased phone will work; moreover, no one can give a 100% guarantee that cutting the SIM card will not lead to a breakdown of the phone. So, how to insert a SIM card into Samsung galaxy s3? So that this does not lead to damage to the device? To do this, just contact any mobile phone store, where they will cut your existing SIM card to the required size for a nominal fee. It is best to do this immediately when purchasing a phone - in this case, any malfunction in the phone. Any damage caused by SIM card cutting can be attributed to the seller's fault.

But, the best thing is not to suffer and not spend extra money, but to order a duplicate SIM card in micro size completely free of charge in the salon of a mobile operator whose SIM card is used by the lucky owner of a Samsung galaxy s3 smartphone. This procedure is completely free and does not require any additional or time-consuming costs. All the phone owner needs to do is write a statement in which they must indicate that they need a micro SIM card. And also when purchasing a new card, for example, if the phone was purchased as a gift, you can immediately order a set of cards, which will include a micro sim and a standard sized sim for regular phones.

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

And all popular mobile operators produce unique constructors - SIM cards in three popular sizes: nano, micro and standard.

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

This evolution of cards allowed them to be reduced by almost half, and modern retractable slots significantly freed up space for other parts.

Let's look at what types of sim there are, what their features are, and how to insert a sim:

• The full-size one (which many people didn’t even know was available) is the largest in the line, with the perimeter like a bank card. It 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 manufactured from 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 like its predecessor, but without the plastic edges. It 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 the same way - into the designated slots in a smartphone or tablet. It is impossible to say exactly where the stand is located, since manufacturers reserve the right to place them anywhere, according to their design concept. Sometimes new phones have a sticker with step-by-step instructions; it can also be found in the User Guide.

Installing a SIM card

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 removable. The following instructions are suitable for owners of the latest type of gadgets:

1. Check if your phone is turned off.
2. Detach the back panel.
3. Locate the small indentation between the case and the battery.
4. Remove the battery.
5. There you will see SIM card slots. They come in different types: separate and two-story. The side you want to hold up when inserting will be shown next to the holder. As a rule, it is inserted with the gold contacts facing down.
6. Carefully insert the battery back. Check that it fits snugly.
7. Return the lid until you hear a characteristic click. They will mean that the lid is in place.

Settings

Modern smartphones and SIM cards do not require manual connection. When you first launch it on a new device, you will receive a package of free settings from your mobile operator for all types of cellular services.

For dual-SIM mobile devices, control can be a little difficult for a beginner. You can choose a SIM for certain actions by default, or choose it yourself for every call and message.

Will a regular SIM card fit into the micro-sim slot?

You can cut a regular size card to micro-sim dimensions if the card is old. However, it is much easier and safer to contact a service center, where they will give you 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 a poorly cut SIM card

However, such experiments do not always end successfully. If the SIM card was cut incorrectly and was damaged in the process, 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 number does 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 indicate 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.
• Failed trimming. We mentioned it above.
• The phone's firmware is tailored for a specific buyer.
• Problems with the slot.
• Failures in the operating system and software.
• The 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 a technician for diagnostics, as these can be either hardware or system problems.

Conclusion

Mobile communications and the Internet are available throughout the day thanks to smartphones and small card modules issued by cellular providers. That is why they need to be treated with care, monitored for their condition and serviceability. The more gadgets come out, the easier it becomes to use SIMs - their sizes decrease, and their capabilities increase. We hope you found this article helpful and provided easy-to-understand instructions on how to handle them in different situations.

Inserting a SIM card into a smartphone seems to be a fairly simple action that does not require special skills, but not everyone can immediately figure out where the connector is, what format of card can be used and which side to insert it in. In this short article you can find answers to these questions that probably torment some owners of the Samsung Galaxy A3.

Each modification of this model has a special holder for SIM cards, which can be removed using the ejector (clip) that comes with the smartphone. The Samsung Galaxy A3 2015 has two trays, and they are both located on the right side panel, where, in fact, the power button is located. The bottom one is intended exclusively for the main SIM card, and the top one can be used for a second SIM card, or for a microSD card. Modifications 2016 and 2017 are equipped with one holder. In the first it is located in the same place as in the A3 2015, and in the second it is on the frame at the top. It can accommodate either two SIM cards, or a SIM card and a memory card. All three variants of the model are “tailored” to work with nanoSIM. It is best to use a SIM card of this format, issued by the operator, and not cut yourself.

How to insert a SIM card into Samsung Galaxy A3

1. Carefully insert the ejector into the hole in the holder and press lightly. If everything is done correctly, the tray should come out of the compartment.
2. Grasp the holder with your fingers and remove it completely.
3. Place a nanoSIM SIM card into it and insert it into the compartment. Be careful not to mix up the sides, otherwise you may damage the compartment or holder.
4. Place the holder back into the compartment.

1. Insert the supplied paperclip into the hole in the tray and press lightly.
2. Carefully remove it from the compartment. This is best done with your fingers.

   

Samsung decided to listen to the opinions of its fans and returned memory card support to the new flagship devices Galaxy S7 and Galaxy S7 Edge. However, she did this using a hybrid slot, as has become fashionable recently. This means that the user must choose whether to use 2 SIM cards or one SIM card and a microSD card in the smartphone. Fortunately, there were craftsmen who discovered that the contacts of the second SIM and the contacts of the memory card are in different places and managed to combine business with pleasure and organize the simultaneous operation of two SIM and microSD cards. And if you have decided to become the owner of a new device (or have already become the owner), despite all its minor disadvantages, then this article is for you. We are publishing a translation of instructions with detailed comments on installing two SIM cards and a memory card in the Galaxy S7 and Galaxy S7 Edge.

Denial of responsibility: You do all the manipulations listed below only at your own peril and risk. Neither the author nor anyone else is responsible for your actions or for any damage caused. There is a high probability of damaging the SIM card microchip, and to a lesser extent, the microSD memory card. Also, when the smartphone heats up, there is a danger of this structure coming off, and in this case problems may arise when removing the tray. It is quite possible that you will have to contact a service center to get it. In this case, the device is removed from warranty.

So, if you are aware of all the risks listed, then to continue you will need the following devices:

• SIM card in Nano format (because it is easier to cut and “disassemble”)
• microSD memory card
• Lighter
• Scissors, blade or any other sharp object
• Thin double-sided tape (preferred) or super glue
• A little free time, patience, a head on your shoulders and straight arms

To install two SIM cards and a memory card at the same time in a Samsung Galaxy S7 or Galaxy S7 Edge, you need to:

• Determine the correct position of the SIM card
  First, you will need to determine the correct position of the SIM card in the tray. Cards from different operators may have different contact configurations. The author of the original instructions carried out operations on SIM cards of U Mobile and Maxis operators (Malaysia). Typically, all SIM cards have a special key on one side (cut corner).

• Detach the SIM card chip from the base
  Any SIM card consists of a plastic base and a microchip with a contact pad glued to it. Gently heat the SIM card from the opposite side (where the plastic is). This may take from 30 seconds to 1 minute. Then carefully separate the chip with the contact pad from the base. It is recommended to use a sharp object (scissors, knife, blade, etc.) as an auxiliary tool. After this, the chip must be cleaned of any remaining glue or plastic.
  If everything went smoothly and you did not have to change the SIM card, then you can consider half the journey completed.

• Trim SIM card microchip
  Now you need to carefully cut the contact pad of the SIM card to fit on the memory card. Usually you need to shorten it by 1-2 mm on each side (as in the photo).

• Secure SIM card to microSD
  This can be done using double-sided tape (in which case the memory card can be easily (more or less) “freed”) or super glue (this option is less preferable, since if you damage the SIM card chip, then separate it from the memory card will be quite difficult or even impossible). The first step was provided for correct placement. In addition, make sure that the corner of the SIM card microchip is aligned as shown in the image (circled in red).

• Place the finished structure in the tray
  Now all that remains is to place the genetically modified microSD card into the tray, and the tray itself into the smartphone.

Finally, you need to check that all actions have been performed correctly. If everything is done correctly, the Galaxy S7 will “see” two SIM cards and a microSD memory card. It will look something like this:

It is also worth noting that the method described above is suitable for all smartphones with the same hybrid SIM card tray. In particular, Meizu Pro 5 owners have a similar experience.

It would seem that placing a SIM card in the Samsung Galaxy S7 is not so difficult. However, it is not surprising that new smartphone owners who have switched to this model from other, earlier ones have a similar question. The fact is that, starting with the Galaxy S6 line models, Samsung decided to combine a slot for SIM cards and microSD cards. As a result, the phone body became monolithic, and the cards acquired a new location. And if previously it was enough to simply remove the cover of the smartphone and insert the SIM card into a special recess, now you can rack your brains quite a bit before finding the right compartment and placing the card there.

How to insert a SIM card into Samsung Galaxy S7

If your device is in active mode, we advise you to first turn off the device. This will prevent the possibility of various errors appearing in the operation of the gadget in the future.

How to remove a SIM card from the slot

In order to perform the reverse operation, that is, remove the SIM card from the device, you need to perform the following steps:

1. To avoid data loss or incorrect phone operation, first turn off your device.
2. Take the key that came with your Samsung Galaxy S7, or a regular paperclip. Don't forget to straighten it first. Insert a key or paper clip into the special hole in the SIM card tray cover. Apply light pressure and when the tray comes out a little from the body, pull it towards you.
3. Once you have the card slot in your hands, remove the memory card or second SIM card (if installed) from it.
4. Then you can pull out the desired SIM card. When performing these steps, be careful, because rough handling of the equipment can damage the contacts and lead to improper operation of the device.
5. Once you have removed the SIM card, carefully place the card tray back into the phone. To do this, you just need to insert it with the correct side into the slot and press down a little so that the tray is fixed in the body.

In the end, it turned out that inserting a SIM card into the Samsung Galaxy S7 is actually not that difficult. It is enough to know where the card slot is located, as well as be a little patient and careful during installation.
