What is the Technician Code?

[naftul]

Hi,

I've come to MIUIAndroid from other roms that has the "*#0011#" code from the dilaler to enter the technician mode, from which i can control the modem in which frequencies and network type it will work (e.g WCDMA 850Hz/900Hz/1800Hz/2100Hz...) but i cant do it with MIUIAndroid.
Can someone tell me how do i enter this menu please?

Thanks!
