Answers: 011 52 55 (then the phone number of 8 digits)

I am not decipherable with the "55" the other answerer tell about. I live contained by Mexico and to call me, my familial uses 011-52 then the nouns code, then the seven digit phone number. the code for mexico is 52+ and de code for Ecatepec is 55 +(8 digits)
