Group 1 - Criminals are targeting children by asking to borrow their smartwatches, leading to theft of SIM cards for fraudulent activities [1][4] - These criminals often operate near schools, selecting younger children who are alone, claiming their phone is out of battery or has insufficient balance [4] - Once they obtain the smartwatch, they quickly remove the SIM card or replace it with a useless one, using the stolen card to make scam calls or send fraudulent messages [4] Group 2 - Parents are advised to instruct their children not to lend their smartwatches to strangers and to report any theft of the SIM card immediately to authorities [7] - To enhance the security of the SIM card in children's smartwatches, parents can enable a protection feature by setting a password through the corresponding mobile app or by inserting the SIM card into a phone [8] - The SIM card's personal identification password is typically set to default values like 1234 or 0000, and it is crucial to change it to ensure security [13]

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]. Group 4: Future Considerations - The article suggests that transitioning to eSIM technology, which eliminates the need for physical SIM cards, could reduce the incidence of such issues in the future [18][20].
