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.

  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.

Replacing the SIM card of Samsung Galaxy S4 is a task that seems difficult and overwhelming considering new standard MicroSIM used in phones of this model. Users who are accustomed 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 S4 SIM card at home.

Instructions

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

Step 1: Pry off the left edge of the back cover of the Samsung S4 with your fingernail or a spatula. A special connector for this is located at the level of the main camera and the power button.

Step 2: Insert a plastic spatula into the gap that has now formed and slide it from left to right, unlocking the latches sequentially (these latches are located along the entire perimeter of the inside of the telephone case). At the moment when the back cover has completely come 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 the special slot located directly under the main camera of the device:

  • Lightly press the edge of the memory card until you hear a characteristic click.
  • Remove the spatula or finger from the card - a click precedes the automatic ejection of the memory card with its retaining tray.
  • Once this happens, remove the memory card and carefully place it in a place where it will not get lost.
  • When assembling the Samsung S4, insert it following the steps in reverse order.

Step 4: Pry up the phone battery, remove it and set it aside.

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

  1. You need to press carefully until you hear the familiar click.
  2. When you hear a click, release the holder so that it can automatically pull the tray out of its slot.
  3. When the SIM card tray appears 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 use than the most ordinary SIM card - 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 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 on mobile markets smartphones appeared, and places for back cover the details were simply lacking. 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 is their peculiarity, and how to insert a sim:

  • Full-size (which many people didn’t even know was available) is 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 manufactured from the 2000s to the early 2010s, supports 2G and 3G.
  • Micro-SIM - appeared in 2003, but on this moment considered the most used generation of communication modules. Supported by all manufacturers 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's 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 are 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.

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 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 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.
  • Crashes in 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.
