2G, 3G and 4G channels/number of Carriers per country

I would like to know if somebody have already mapped the GSM, 3G and 4G channels or carries per country.
Actually I need this information for southern cone countries, I have already searched on several websites and could not find the number of carriers per band.
I am looking for any site or information that relates the operator versus the frequency band and number of carriers as the following table:
