Hi, 1) What is your clock offset, according to Kalibrartor? 2) Could you write at OpenBTS wiki how to activate netmon on Siemens phones? I used to re-flash them, because patches to activate netmon are available for many (if not all) Siemens phones and then you don't depend on SIM-card, but the way with SIM-card may be easier for newcomers.
