Card slot insert reverse solution:
1, prepare a plastic film, not too thick, not too soft.
2. Cut the plastic film into strips about one centimeter wide.

3, insert the card from the side of the card slot until it cannot be inserted (must be inserted in the innermost!) The aim is to create the effect shown in the picture, so that the film covers the groove and avoids bending the internal metal pin when pulling out the card slot.

4. Carefully pull out the card slot. If the resistance is greater, the film should not completely cover the card slot. First check whether it is inserted into the innermost part, or whether it can be widened appropriately.

Some mobile phone card slots are not designed with a convex slot to prevent reverse insertion, which can sometimes be accidentally inserted. If pulled out hard, it is easy to damage the pin used to read the SIM card in the phone.
