NCC allocation is typically done by the regulatory authority within the country.

If you have less than 8 operators, it is likely they will assign one NCC to
each operator, in addition to the MNC.  If there are more operators, it would
make sense to have an even distribution ov the NCC values among the operators.

NCC is only used when detecting SYNC Bursts (SB), as soon as the phone decodes
the BCCH, it will know the MCC/MNC and ignore it, if it's not the network it
has been looking for.
