Why 2 different IMSI are being broardcast

Greetings,

I'm new to this forum so please don't bite my head off.

I have an EVDO air card that is broadcasting two IMSI at the same time.

For example, I used the QSPT tool to program the EVDO revA card with an IMSI of 432124993991234.

When a test call is executed the EVDO card is broadcasting two (2) IMSI.

The second IMSI broadcast would be 121324331221234.

The EVDO test call works because the 432124993991234 is programmed on the network but why is the second IMSI 121324331221234?

Does anyone have any idea?

Is this how it works?

Are there any spec. or 3GPP standard to support this.

Thanks in advance!
