Test SIM Card Specification：
Grcard 2.5G Test SIM Card Can use in The Agilent 8960 and others.to test set when
running any GSM test or lab application.
The USIM has several benefits:
UMTS security variables within the SIM match the default settings of the GSM test
and lab applications.
Setup time is reduced because the SIM is configured with the same default IMSI and
PLMN values broadcast from the test set.
For dual-mode testing, GSM speech loopback is supported for GSM Bit Error Ratio
(BER) measurements.
