Where is the micro SIM card inserted into the Samsung 19100? Installing a SIM card on the Samsung Galaxy S7

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 to be held 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.

In the video you can see what to do with modern models whose lids cannot be removed:

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, the controls 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 need to 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, since 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.

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.

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.

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

This guide will tell you: what size is used, 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 identification module), which can be obtained from any telecom operator (MegaFon, MTS, Beeline, Tele2, etc.).

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

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 in the market and no Android phone has used this size.
2. Mini-SIM (2FF). In some countries it is usually referred to as a "large", "normal" or "standard" SIM card. Most carriers and phone manufacturers phased them out several 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 smartphones. Most flagship smartphones require this.

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

If you just purchased a new flagship from Samsung, and previously used another phone, then you may already have 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+) too.

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

What is slot 2 in the SIM card tray?

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

Slot 1 is always for 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 SIM card into Galaxy S8 and S8+, you need to follow the following 5 steps as shown in the image below.

Step 0: Turn off your phone.

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

Step 2: Carefully pull out the tray.

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

Step 4: Secure it.

Step 5: Reinsert the tray.

Step 5/1: Turn on your phone.

How to remove or replace the SIM card?

You can remove or replace the SIM card, similar to 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.
• Technically they have dual standby modes rather than two active modes. 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 operator's network.

In the dual-SIM version, control 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.

Samsung Galaxy S7 and Galaxy S7 Edge mobile phones work with Nano SIM cards. Therefore, if you bought this device to replace an outdated mobile phone, you will most likely need to change the SIM card at a customer service point or independently format the card into the desired format. Many users choose the second option, since contacting a service center may be associated with certain difficulties. Let's look at how to cut and install a SIM in a Samsung Galaxy S7.

Procedure for cutting SIM cards for Galaxy S7

NanoSIM is a relatively new format for SIM cards. It first appeared in the iPhone 5 and is still used in all Apple devices. A little later, smartphones from the Samsung Galaxy line began to be equipped with Nano-type card holders. This approach has made it possible to reduce the size of mobile devices and make them more convenient to use.

If your previous gadget worked on a Mini- or Micro-SIM, then before inserting such a SIM card into the Samsung Galaxy S7, it must be cut correctly. To perform the upcoming work, prepare the following tools and materials:

• cutting template (you can download it from the Internet and print it on a printer);
• thin scissors or stationery knife;
• scotch;
• thick rags or fine-grained sandpaper.

The procedure for cutting a SIM card to Nano format is as follows:

The NanoSIM card is ready for further use.

Installing a SIM card in Samsung Galaxy S7

Installing a SIM card in the Galaxy S7 is done in the following sequence:

If you cut a SIM card yourself, there is a small chance of damage to its microcircuit. Therefore, if your smartphone does not want to accept the card, replace it with a new one at your operator’s subscriber service center.

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 stationery 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. It is also worth paying special attention 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.
