Radio Communication Analyzer setup for Q2438

Hi, I am trying to set-up a connection between a radio communicatioin analyzer (R&D CMU200 and Anritsu MT8801C) and the Q2438J (Verizon). I eneterd parameters such SID/NID, MCC, RF channel (previously obtained from the Q2438 via AT commands) into the instrument but the module does not want to register with the network. Are there any other parameters I need? Is this because the module is already provisioned for Verizon and thus does not accept the radio coimmunication analyzer network? Any suggestions? I live in Europe so I cannot try to connect to a real provider (we have only GSM network here).
