SIM card is (Subscriber Identification Module), also known as user identification card, mainly used in GSM, WCDMA, LTE, 5G and other networks, and consists of CPU, ROM, RAM, EEPROM and I/O circuits.
The size of the SIM card is divided into three types: Standard card (commonly known as large card): the size is 25mm×15mm×0.8mm, Micro Sim (commonly known as the medium card): the size is 12x15mm×0.76mm; Nano SIM (commonly known as the small card): 12.3 mm×8.8mm×0.67mm.

SIM cards are also commonly used in the testing of various communication terminals such as signal, voice, traffic, bit error rate, etc., such as mobile phone terminal production, base station systems, and operators’ commercial applications. SIM cards are commonly used in GSM networks, WCDMA networks, LTE networks, and all 5G frequency bands (China Mobile (2 frequency bands) 2515MHz-2675MHz and 4800MHz-4900MHz, China Unicom (1 frequency band) 3500MHz-3600MHz Telecom (3400MHz-3500MHz), etc. Related equipment testing and application, etc.

The SIM card cooperates with the comprehensive tester to perform non-interference comprehensive testing on mobile phones, etc.; mobile phones and other terminals need to perform related signal tests on the finished products during production, but large-scale screens are required, which requires more manpower, material resources and testing time to make production The process is complicated and the cost increases. The SIM test white card can realize the path from the signal to the instrument to the mobile phone terminal, which makes the test environment more concise and solves this complicated problem.
.
