Hi Kevin.
He he, I am afraid these mysterious radios numbers will stay mystery for me and other people. I do not understand it. Even if we assume that given radio is designed for given country gsm infrastructure ( it is pure speculation because as I know there are 3 gsm frequncies over the world so what difference may it be ?), people are traveling across the countries and their smartphones must work even then. I suspect that with given radio may be associated maximum power transmission like in wi-fi networks for given country.
Regards
Jacek
