2.If you want to recover the SIM card, just insert the card into the labeled recovering card and stick it tightly.
3.For some types of phones with transverse inserting and hidden card, there are eight protruding labeled stainless steel flakes to avoiding the pulling difficulty. Such types as we know include: MOTO V70; NOKIA 8250, 8210, 3230, 2100, 6260, 6650, 8800,etc. For normal phones, you are kindly suggested to use the labeled stainless steel flake with 12 protruding parts on each side. This kind of flake could make the products touch much more tightly and make the processing steadier. It is just one of our patent items.
