Core Viewpoint - The article discusses the phenomenon of SIM cards burning out in mobile phones, particularly after OTA updates, and explores the underlying reasons for this issue. Group 1: SIM Card Malfunction - Users have reported instances of SIM cards burning out, leading to loss of service, which has been corroborated by multiple accounts on social media [1][3][11]. - The article highlights that SIM cards are not merely plastic cards but electronic components that require power and communication with the phone's motherboard [4][7]. Group 2: Technical Explanation - The power supply standards for SIM cards, as defined by international organizations, include voltages of 1.8V, 3.3V, and 5V, indicating that incorrect voltage supply can lead to damage [5]. - The potential for SIM card damage during OTA updates arises from the phone's processor controlling the power supply to the SIM card, which could malfunction during firmware updates [8]. Group 3: Physical Factors - Overheating of the phone during updates, especially in models where the SIM card slot is close to heat-generating components, can also contribute to SIM card failure [8][9]. - The article mentions that physical wear, such as oxidation of the SIM card's contact points, can lead to communication failures between the SIM card and the phone [13][15].
