Turn off roaming data connection

[Guest corvettec3]

Hi, I've 4.4.032 official rom on my 8297w. I want to turn off roaming data connection ( I want that my phone, when data connection is on, it will connect only to my network operator. When my operator is not available phone won't connect to others operators available). If I go to settings-more-mobile netwoks I don't find roaming data. Can you help me? thanks

I'm not sure that all ROMs have such an option.

I'm not familiar enough with the official ROM to say whether or not it has.

I'm on AOSP A310 myself.
