Operator commands

[mousio]

When "calling" special numbers such as *444*# or #121# (to get a message with my remaining credit) or similar codes for operator commands, I do not get the expected message back but luckily the call does get processed (by the operator).
All I see is a balloon saying "Waiting..." with an OK button, but the answer from the operator never shows (unless it is an unknown code/command!).

I tried with the following ROMs (some WM6, some WM5) but only the HTC ROM (from europe.hct.com) works OK with these operator commands:
- AX3L_OS_v2.0.8.1 (WM6)
- LVSW_Trinity_WM6_v2.0.1.1 (WM6)
- LVSW_Trinity_WM6_v2.0.0.1 (WM6)
- mUn_2.01.TE_WWE_GPS (WM6)
- LVSW_WWE_1.25.0.8_GPS_AKU3.5.2 (WM5)
- RUU_Trinity_HTC_NLD_1.23.404.2_103_6275_1.38.00.11 _108.exe (WM5)

Does anyone have a clue?

It seems to be an issue of the RADIO ROM, for instance 1.38.00.11 works OK with Simyo and Proximus whereas 1.46.00.11 works OK with Simyo but not with Proximus?!
