The mobile phone card slot does not respond when poked with the card removal needle
When many users use the card removal needle to take out the mobile phone card in the SIM card slot MIM Parts, they will find that there is no response. Talk about the reasons for this situation and how to solve it.
1. Insufficient strength
We need to figure out the difference between the phone card tray and the card slot first. Under normal circumstances, when the card pin is inserted and inserted, the phone card tray pops up. Its function is to carry the phone card and memory card, and to fix the position of the phone card after it is inserted. To prevent the phone card tray from popping up or moving for no reason, the inside is locked by a mechanical bracket. Only by inserting the card removal pin can the bracket be opened, and the card tray will pop out. However, the bracket is stuck tightly and requires some force to open.
If you cannot open it, you can try to increase the force, and the card tray will pop out. Many users dare not use force because they are afraid that the card needle will damage the internal parts of the mobile phone. In fact, the card tray and card slot of the mobile phone are not so expensive.
2. Deformation of card tray or mobile phone card
This kind of problem is the most difficult to solve. Under normal circumstances, the phone card holder will fix the phone card in a specific position, so as to ensure that the chip on the phone card is in full contact with the spring striker on the card slot. However, if the mobile phone card is deformed or the card tray is deformed, the mobile phone card, the card tray and the card slot will not be on the same plane. When the user inserts the pin into the small hole next to the card tray, the card tray or the mobile phone card will be stuck in the card slot and cannot be ejected. If the force is too large, the mobile phone card or card slot may be damaged.
In this case, there are two ways to try, one is to use thin enough but a little hard plastic, insert it against the gap of the card holder, then move it back and forth, and then try to take it out with the card removal needle. As shown below:
However, it should be noted that some mobile phones have a small step on the outside of the card tray, which may not be able to insert plastic sheets, and many mobile phones have a rubber ring on the outside of the card tray to prevent dust and water, so this method It depends on how big the gap is at the socket of the card tray of the mobile phone; the other method is more troublesome, and needs to use a card removal needle to gently touch the small hole next to the card tray. As shown below:
In the process of testing back and forth, use your fingers to touch the card tray lightly. When pressing the card removal needle, release the hand holding the card tray. When releasing the card removal needle, press the card tray again and try it back and forth There is a certain chance to restore the deformed card tray or mobile phone card to its original shape, and then take it out smoothly.
3. The card slot is damaged
In addition to the problem of the mobile phone card or the mobile phone card tray, there is another situation caused by the damage of the card slot. This kind of problem is not particularly common, but it does happen occasionally, such as the mobile phone being dropped, the card needle being inserted too hard, the mobile phone card, Foreign objects inside the card slot will prevent the phone card tray from being removed. If it is forcibly removed, the card slot or other parts of the phone may be damaged. Card slot structure, as shown below:
If the first two methods fail to remove the card tray of the mobile phone, do not try it by yourself. Regardless of whether the mobile phone has passed the warranty period, you can go to the mobile phone after-sales repair shop to help check it. If it is within the warranty period, it is determined that it is not In the case of man-made damage, it can be repaired and replaced for free. If the warranty period is over or it is man-made damage, you can pay for repairs, and the cost is not expensive.
In most cases, the reason why the phone card tray cannot be removed is that it is not strong enough or it is stuck. The former can be removed with a little force, but if it is stuck, the possibility of taking it out by yourself is low. It must be combined with the phone model, The internal structure style and card slot style determine which method to use to take it out, but the most thorough and direct way is to disassemble the machine.
