Self-installation of SIM cards in Samsung Galaxy A5. Installing a SIM card on a Samsung Galaxy S7

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. Smartphones first appeared in mobile markets, and space for back cover details were simply not enough. 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 almost halved, 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 cellular communication 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 on this moment considered to be 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, 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. Following Instructions suitable for owners of the latest 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 different type: separate and two-storey. 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 dual-SIM mobile devices, management can be a little difficult for a beginner. 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.

Embed a sim that has mechanical damage, Not recommended.

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 for diagnostics to the master, 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.

Samsung decided to listen to the opinion of its fans and returned to the new flagship Galaxy devices S7 and Galaxy S7 Edge support memory cards. However, she did it with the help of a hybrid slot, as it has become fashionable lately. This means that the user must choose whether to use 2 SIM cards in the smartphone or one SIM card and a microSD card. 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 to organize the simultaneous operation of two SIM and microSD cards. And if you decide to become the owner of a new device (or have already), despite all its minor disadvantages, then this article is for you. We are publishing a translation of the 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 and for possible damage caused. There is a high probability of damaging the microchip of the SIM card, to a lesser extent - the card microSD memory. Also, when the smartphone is heated, there is a risk of this design peeling off and in which case problems may arise when removing the tray. It is possible that you will have to contact the service center to get it. In this case, the device is removed from the warranty.

So, if you have realized all the listed risks, then you will need the following devices to continue:

• Nano SIM card (because it's easier to cut and "take apart")
• microSD memory card
• Lighter
• Scissors, blade or any other sharp object
• Thin double-sided tape (preferred) or super glue
• Some free time, patience, head on shoulders and straight arms

To install two SIM cards and a memory card at the same time samsung galaxy S7 or Galaxy S7 Edge you need:

• Determine the correct position of the SIM card
  First you need to determine the correct position of the SIM card in the tray. Cards different operators may have different contact configurations. The author of the original instruction performed operations on SIM-cards of operators U Mobile and Maxis (Malaysia). Usually 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 pad from the base. As an auxiliary tool, it is recommended to use a sharp object (scissors, knife, blade, etc.). After that, the chip must be cleaned of adhesive or plastic residues.
  If everything went smoothly and you did not have to change the SIM card, then you can consider half the path passed.

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

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

• Place the finished structure in the tray
  Now it remains to place the geno-modified microSD card into the tray, and the tray itself into the smartphone.

Finally, you need to check the correctness of all actions. If everything is done correctly, then 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 tray. In particular, Meizu Pro 5 owners have a similar experience.

With new Samsung smartphone The Galaxy S7 has brought back the micro SD card slot.

Although Samsung has introduced "flexible storage technology" (it appeared in Android 6.0), it is now possible to move applications to the SD card.

If you decide to upgrade to the S7 device model from the previous model, then you already know that there is a twin tray inside any version of the Galaxy A7.

It allows you to initially install either one SIM card and microSD card, or two SIM cards in nano-SIM format. This is usually an inconvenience, as users often want to use two SIM cards at the same time and expand the memory.

In addition, difficulties often arise and you can often hear the following question: "How to insert a SIM card into the Samsung Galaxy A7."

"Craftsmen" drew attention to the fact that the contacts of the second SIM card and the card Micro memory The SDs are located in different places. This means that they can simply be combined if necessary. However, they work great at the same time.

Since for many it turns out to be an unexpected location for a flash drive and a SIM card, we decided to compile this instruction. From it you will learn how to put SIM cards in Samsung Galaxy S7.

Peculiarities

For example, for Moto X Pure Edition users, the process of inserting a SIM card is familiar, because the manufacturing company in the Galaxy S7 line has done the same. Namely, I combined the micro SD tray with the SIM card tray.

So what and where do you need to insert if you don’t understand this? Now you will know everything. To do this, simply follow the instructions below.

Instruction

1. Turn off your phone.
2. On the upper side of the smartphone, find the hole from which you need to remove the SIM card tray. It is located closer to the front if you turn the device towards you with the display. It is not difficult to notice it, it is quite large.
3. A special tool must be inserted into the hole to remove the tray. The tool is usually sold with the phone, it looks like a small key. Insert it and press lightly. If you do not have such a tool, you can replace it with a straightened paper clip.
4. After you press the tray, it will slightly pop out of the edges.
5. Pull out the tray completely.
6. Gently insert the SIM card into it. Do this carefully, because there is no latch in the tray. Important! You need nano SIM card. It must be put into a smaller slot.
7. Insert a micro SD into the larger slot. It doesn’t matter which side you put it in, since there is only one insertion option, so you simply won’t be able to insert it incorrectly.
8. Bring the tray close to the device. Do this carefully so that nothing moves out of its place.
9. Slide the tray back into place without much effort.
10. Turn on your smartphone. Ready.

This instruction also applies to the Galaxy S7 Edge. We hope you did it without difficulty and now you know how to insert a SIM card into Galaxy A7.

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

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

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, for mobile phones exists 4 different sizes kart:

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 of the middle 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 just like this is required.

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

If you just bought a new flagship from Samsung and used another phone before, 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 more. 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 at the same time like active phones with two SIM cards. 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.
