Ok, I think numbering the digits from 1-3 was confusing because
it made unclear which one is the most significant one.

Digit 1 is the most significant one, the first one when reading
the decimal number from left to right.

[0] MCC digit 2, MCC digit 1
[1] MNC digit 3, MCC digit 3
[2] MNC digit 2, MNC digit 1

Sorry for the confusion, Pascal: too many errors in my first email!
You are right, it is the standard BCD encoding from 3GPP.

I will continue working on my merge request.

Thanks,

Mauro
