    2. Using adhesive tape, in other words, PVA glue, attach an existing SIM card to the template. The zero point, which is why it is necessary to navigate when fixing a SIM card, is a cut corner. With all this, if the initial card has the size of Micro-SIM, the MicroSIM to NanoSIM template is suitable for you. In this case, there is a real SIM on hand, use the MiniSIM to NanoSIM template.
    3. With thin scissors, in other words, with a clerical knife, cut the protruding plastic along the lines drawn. It is necessary to work very carefully so as not to accidentally destroy the microcircuit.
    4. Take a walk around the cut edges with fine sandpaper without too much interest. This will allow us to remove what remains to our client to do with burrs, which, if necessary, may interfere with the normal insertion of the card into the corresponding slot.

If this does not work, try to remove and re-insert the card additionally.

    What you need to know about the SIM-card slot in the Samsung Galaxy S8

    To correctly install the SIM card in Galaxy S8 or Galaxy S8 Plus, you should deal with some features of the SIM card slot in solving this issue with the device, but directly:

    The designated connector is located on the upper end of the phone in the left corner. It is rubberized, which prevents dust and water from getting inside the accessory.

    The tray is issued in 2 standards: European and Asian. First, you can put one Nano-SIM and a microSD card in it, and in the second. two SIM cards in a different combination of Sim external memory.

  • The product is revealed by means of a special key-clip that comes with the device. If the passage of its absence, an ordinary clip is used, for having previously unbent one of the ends, or a needle.
  • Removing and installing mobile cards is carried out only when the power is off. In another way, sometimes a software malfunction occurs on the phone in another way.
  • External slot, with blanking plate and without drawer

    This is a transitional option. here, to get to the slot, you no longer need to remove the panel that covers it, but the SIM card tray is not yet included in the design.

    How to insert a SIM card into a Samsung tablet or into another device of a similar design:

    • We are looking at the housing and moving aside the slot cover of the slot. Depending on the brand and model of the tablet, it can be located on its right or left edge, or on the upper end.
    • We insert the SIM card into the slot, after expanding it according to the picture / print on the plug.
    • We heat the card into the device case. you can help a little with a fingernail or a thin flat object.
    • We return the cap to the place.

    By the way, some Lenovo tablet models do not have a regular slot under the plug, but with a pull-out tray. Its side is slightly convex and it is easy to grab onto it. The chip in this tray on the Prestigio is placed as shown on the plug.

    How to remove a SIM card from such a slot

    Perhaps the above instruction on how to insert a SIM card into a tablet seemed familiar to you, and you had a hunch in your head how to remove a card.

    Yes, the same principle really works here, which is used for SD cards in cameras and laptops:

    1. We remove the plug. As you can see, the SIM card “sits” deep in the slot and grabbing it to pull it does not work.
    2. Press with something flat and firm on the visible edge of the card. Lightly so that the plate goes a little further into the case. And immediately release.
    3. The edge of the chip extends a couple of millimeters outside the body. We take our fingers over this edge and pull the card out.

    SIM Card Size

    A smart watch is a small gadget, so there is not much space inside for a SIM card. Telecommunications operators today release SIM cards in three sizes:

    • Mini-SIM. 2G, 3G
    • Micro-SIM. 3G, 4G
    • Nano-SIM. 3G, 4G

    Of all the sizes that exist today, with a greater degree of probability, you will use the last two formats. micro and nano. Which SIM card to choose will depend on the model of the watch.

    When buying a new SIM card, choosing the right size is easy. On a standard plastic card, they are presented at once in three types. The user can only select the desired one and squeeze the template.

    In the case that there is an old-style SIM, then you have three options for how to proceed:

    1. Buying a new card is the easiest and most expedient, in addition, you can choose any phone number in this case
    2. Writing a statement at the office of a mobile operator to replace and issue a copy of a new sample is the longest way
    3. Trimming your old SIM card with a pattern is the most risky way

    When a working SIM card of the right size is prepared, you can begin to configure and activate it.

    Types of SIM Cards

    SIM cards are an identification module of a subscriber of a telecom operator. From the moment of their launch to the beginning of mass sales, several decades passed, and during this time their shape and size improved. This process was forced. First, smartphones appeared on the mobile markets, and there was simply not enough space under the back cover for the details. Technologies have improved, user requests have increased, batteries are getting bigger, phones are thinner, and there is less space.

    This evolution of cards allowed them to be reduced by almost half, and modern retractable slots noticeably freed up space for the rest of the details.

    Let’s look at what kinds of sim are, what is their feature, and how to insert a sim:

    • Full-size (the presence of which many did not even guess) is the largest in the lineup, along the perimeter like a bank card. It appeared in 1991 with the first wave of the popularity of cellular communications among ordinary residents. It is not used in modern phones, sometimes you can come across cars with similar “innovations” a la 90s.
    • Mini-SIM. is still used for devices released from the period of the 2000s to the beginning of the 2010s, supports 2G and 3G.
    • Micro-SIM. appeared in 2003, but is currently considered the most used generation of communication modules. It is supported by all manufacturers of modern gadgets with 3G and LTE.
    • The smallest is Nano-SIM, which looks like its predecessor, only without plastic edges. It appeared five years ago, and is used in all models of the Apple brand and some other manufacturers of the premium segment.

    All kinds of SIM cards are inserted the same way. in the designated slots on a smartphone or tablet. It is impossible to say exactly where the stand is located, as manufacturers reserve the right to place them anywhere, according to their design concept. Sometimes a sticker with a step-by-step instruction is glued on new phones; it can also be found in the User Guide.

    How to insert a SIM card into a tablet

    With the fact that there are different SIM cards, we figured it out. So now move on to the next one. Let’s talk about how to insert a SIM card into a tablet:

    Turn off the device first. Then lay it on a flat surface with the display facing down. You can lay a towel or some fabric so as not to scratch the front of the gadget.
    Most tablet models have a SIM card slot on the side (sometimes on the back cover). It can be covered with a special shutter, which must be moved or pulled out by prying with a finger, fingernail or other thin object. On some devices, you can get to the SIM card slot only by pushing an i-clip into a special hole. There are also models where you just need to press the lid and release. Then the SIM tray protrudes out of the slot
    If you cannot pull out the tray, you can use a needle or tweezers

    Just be careful not to damage the device.
    When you get to the tray, you need to install a SIM card in it. This is done quite simply.

    over, the holder itself has the shape of a SIM card with a beveled angle. You can confuse only the side. Therefore, be guided by the fact that the contact part of the SIM card is turned up and directed toward the rear panel, and not towards the display. Sometimes there is a hint on the tray itself on how to position the SIM card correctly.

    Next, insert the SIM tray into a special slot. Most often, a small pressure on it is required in order for it to lock securely. In this case, great effort is not required, otherwise you can break the mounts or the holder itself.
    We are trying to turn on the tablet. If everything was done correctly, the device will recognize the SIM card, and then give the user the opportunity to make calls and provide him with Internet access.
    However, it happens that the tablet does not see the SIM card. The most common reason for this is incorrect installation. Pull out the tray again and make sure that the SIM card is firmly fixed, that it does not protrude and does not fall
    Pay attention to whether you placed it in the holder with the right side.
