Dear Sir,
There are few fixed line telecom operators in Brazil. i.e. Embratel, Brazil Telecom etc.
Now my question is, from a Brazil Geographic telephone number, how do we find the operator to which this telephone number is belongs to?
in other word, how to find the operator from a telephone number in brazil.
(Qutsion Not related to mobile phone operators. only fixed line operators.)
Thank you.
