I'm trying to start a BIP session from my java sim card through a Nokia E60. However each time I send the PUSH command (ETSI 102 226), the phone simply does not start the session. In fact it appears instead to perform a location update to the network. What OPEN CHANNEL parameters must I provide in the BIP PUSH command to open a BIP channel to use for CAT_TP? The SIM does support BIP/CAT_TP and works well in an emulator.

Thanks in advance
