omsocombb not receiving calls

I tried two sim cards one that works fine and another one that doesn’t get paged, I noticed that during the location update procedure everything is exactly the same (using wireshark). The log files are also similar. Although both cards work fine if used in a normal phone (even with a motorola c123/118 …).
Another thing to mention is that some sim cards only work when i stick them on a BTS that has the "SI type 3, GPRS indicator" as follows:
"3G Early Classmark Sending Restriction: Neither UTRAN, CDMA2000 nor GERAN IU MODE CLASSMARK CHANGE message shall be sent with the Early classmark sending"
while they can only make calls without being able to receive anything on other BTS where the "SI type 3, GPRS indicator" is as follows:
"3G Early Classmark Sending Restriction: The sending of UTRAN,CDMA2000 and GERAN IU MODE CLASSMARK CHANGE messages are controlled by the Early Classmark Sending Control parameter"
I would be very grateful if anyone has some explanations to what is going on.
