I would like to know why electric contacts in SIM cards fail to work
after many uses

Electric contacts in SIM cards can fail to work after many uses due to
several reasons:

    Wear and Tear: The most common reason is physical wear and tear.
Every time you insert or remove a SIM card, the metal contacts on the
card rub against the contacts in the SIM card slot. Over time, this
friction can wear down the thin layer of metal on the SIM card, leading
to poor connectivity or complete failure.

    Oxidation and Corrosion: The metal contacts on a SIM card can
oxidize or corrode over time, especially if they are exposed to moisture
or contaminants. This oxidation can create a barrier that prevents
proper electrical contact between the SIM card and the device.

    Dirt and Debris: Dust, dirt, and other debris can accumulate on the
SIM card contacts or in the SIM card slot. This can interfere with the
electrical connection, causing the SIM card to fail to work properly.

    Bending or Physical Damage: SIM cards are relatively fragile and can
be easily bent or damaged if not handled carefully. Physical damage to
the card can break the internal circuitry or damage the contacts,
rendering the card unusable.

    Manufacturing Defects: In some cases, the SIM card may have had
manufacturing defects that only become apparent after extended use.
These defects can lead to premature failure of the contacts.

    Electrical Surges: Occasionally, electrical surges or static
discharge can damage the SIM card's contacts or internal circuitry,
leading to failure.

Preventive Measures:

    Handle with Care: Always handle SIM cards gently and avoid frequent
insertion and removal.

    Keep Clean: Keep the SIM card and the SIM card slot clean and free
from dust and debris.

    Avoid Moisture: Keep the SIM card away from moisture and extreme
environmental conditions.

    Use Protective Cases: If you frequently switch SIM cards, consider
using a protective case or holder to minimize wear and tear.

If your SIM card has already failed, you may need to contact your mobile
carrier to get a replacement. They can often transfer your existing
account and data to a new SIM card.
