Why one same USIM card has two IMSI?

I want to get IMSI invoking TelephonyManager.getSubscriberId(), but sometimes get 334050xxxxxx, and sometimes get 222013xxxxxx, why? I use the some one USIM card.

Most likely your card has Dual IMSI application (or Multi IMSI application). One IMSI is used for home and partners network, and another one for international use (roaming).

I suggest to use ICCID for identification, because it is unique for each card. You can use Telephony#getSimSerialNumber().
