We should have different json files per mcc/mnc, if we will configure more stuff, we will end up having all customisations in a single file, and that could be huge, meanwhile we will just need to load a small pice of json,

What if we do this:
`/ftu/js/variants/mcc1-mnc1.json`

And during the build process we can fill that directory with as many combinations as needed.

Do you like the idea?
