I would recommend you to try to get hold of an old Siemens S45, SL45 or ME45. They support only non-EDGE GPRS and have some nice monitor features available when activated (instructions are easy to find). Amongst other things it's possible to attach/detach GPRS, activate/deactivate PDP context, IP ack/unack, and so on, via menu. And using a serial cable these phones support the at+crsm-command so you have read access to TMSI, Kc and other files on the SIM during operation.
