Replace SIM samsung galaxy S4 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 guide 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:
- You need to press it gently and until a click is familiar to us.
- When you hear a click, release the holder so that it can automatically pull the tray out of the slot.
- When the SIM card tray has appeared completely, it's time to remove the SIM card from it.
- Now you can insert another card into the slot and put the phone back together.

And if earlier it was enough just to remove the cover of the smartphone and insert the SIM card into a special recess, now you can break your head well before finding the desired compartment and placing the card there.

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 on mobile markets smartphones appeared, 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 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 located, as the manufacturers reserve the right to place them anywhere, according to their design concept. Sometimes a sticker with step-by-step instructions is glued on new phones, you can also find it in the User 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:
- Check if your phone is turned off.
- Detach the back panel.
- Find a small indentation between the case and the battery.
- Remove battery.
- 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.
- Insert the battery carefully back. Make sure it fits snugly.
