Using [wiki:SIMtrace], you can sniff the initial communication between a 3G phone and a USIM in order to get the phone terminal profile (it should even be before the PIN check).
It is also decoded in wireshark.

The terminal profile CAT command header (CLA=80, INS=10, P1=00, P2=00) is defined in [http://www.etsi.org/deliver/etsi_ts/102200_102299/102221/ ETSI TS 102 221] §11.2.1.
The terminal profile CAT command body is defined in [http://www.etsi.org/deliver/etsi_ts/102200_102299/102223/ ETSI TS 102 223] §5.2.
It tells the USIM what it can do on the phone.

There is now a collaborative project on creating a database of terminal profile records of many different phones, you can reach it at https://terminal-profile.osmocom.org/

That page also contains instructions on how to contribute to the database - which we hope you will do, at least as long as you have a SIMtrace or other hardware to obtain it from your phones.
