What is a test sim card?

The GSM test card, CDMA test card, UIM test card, RUIM test card, WCDMA mobile phone test card, TD-SCDMA test card, CDMA2000 test card, mobile phone test card use special chips from international famous semiconductor manufacturers. 3V/5V compatible and 5-6 contact compatible design, suitable for all mobile phones. With dedicated COS system, fully comply with 3G mobile phone, TD-SCDMA test card specifications, special semiconductor silicon lining, to ensure that the card can withstand 10 Newton/pressure per square meter. (The GSM standard is 4 Newtons per square meter) Suitable for industrial production lines. It uses ultra-long-life EEPROM to ensure that the number of reading and writing is more than 100,000 times. (The 3G standard only requires 30,000 times. According to the general production line measurement requirements, the number of reading and writing of each mobile phone is 10 times, and 10,000 mobile phones can be measured.) The patented chip protection layer ensures card security and electronic attacks.

There are four types of SIM test cards:
GSM card: For mobile phone factory test, used for test display, mobile phone processor, mediator version, display voice plus password, restore call time, etc.
CDMA card: It is used for mobile phone factory test, used for C network test display, mobile phone processor, mediator version, display voice plus password, restore call time, etc.
WCDMA card: It must pass the instrument test, and which instrument is tested. There are generally three kinds of instruments: Agilent (8960), Rohde & Schwarz (CMU200), Amway comprehensive tester.
TD-LTE card: TD-LTE (CMW5000) mobile test card micro, nano test card, for mobile phone factory test, for test display, mobile phone processor, mediator version, display voice plus password, restore call time, etc.
We provide both test sim card android and test sim card iPhone, We designed the LTE 4G Series USIM cards meet the current market demands rapid development of the fourth generation of mobile communication, according to domestic and foreign carriers to promote the use of 4G networks, independent research, and development of new smart card products for TD-LTE and FDD LTE and another network. In terms of compatibility, it applies not only to the 4G network but also backward compatible with 3G, 2G network can successfully adapt to the transition from the era of 3G to 4G market If you have special requirements, you can provide parameters or sample customization.

Sim test card, mobile test sim card widely use in the communication industry, it works with sim card test tool (Agilent 8960, Anritsu, CMU200, CMW500/ TD-SCDMA, etc.) to test mobile phone without interference during produce the mobile. The test sim card can shield the external signal and make it is one way to transfer the signal from the test sim card to mobile phone. It makes the test environment is simple. The main test functions include test display, mobile phone processor, mediator version, voice and password display, call time reduction, coupling test, bit error rate test, etc. The main test cards include mobile GSM, TD-SCDMA, Unicom’s WCDMA, Telecom CDMA, CDMA2000/EVDO, and other network test cards and test cards
