Recently, the claim that ‘each SIM card contains 0.02 grams of gold’ has circulated online, but verification confirms it is a myth. While SIM cards do contain trace amounts of gold, the quantity is minimal and far less than 0.02 grams. Modern SIM cards use gold-plated contacts with a thickness of approximately 0.1 micrometers, primarily to prevent oxidation and ensure signal stability. Estimates show that a standard SIM card actually contains less than 0.0001 grams of gold, worth only a few cents. If each card truly held 0.02 grams of gold, the cost would be several dollars—far exceeding the actual price of SIM cards. This rumor likely stems from misunderstandings about gold plating in electronics or exaggerated claims by recyclers seeking to inflate the value of e-waste. Consumers should approach such information rationally and avoid unrealistic expectations regarding SIM card recycling.
近日，网络流传“每张SIM卡含有0.02克黄金”的说法，经多方核实，该信息属于谣言。事实上，SIM卡中确实含有微量黄金，但含量极低，远未达到0.02克。现代SIM卡的金属接触点通常采用镀金工艺，金层厚度仅约0.1微米，主要作用是抗氧化、保证信号稳定。以一张标准SIM卡估算，其黄金含量实际不足0.0001克，价值仅几分钱。金作为贵金属，若每张卡真含0.02克黄金，成本将高达数元，与SIM卡实际售价严重不符。该谣言可能源于对电子元件镀金技术的误解，或个别回收商为炒作电子垃圾价值而夸大其词。消费者需理性看待此类信息，避免对废旧SIM卡回收产生误导性期待。
