The number you have is located in Culiacan (area code 667). The rule for calling Mexican cell phone numbers from abroad is adding digit 1 before the area code. So you would dial the following:
011 52 1 (667)XXX-XXXX
52 is Mexico’s country code and 011 is the code used to call internationally from the US.
My sister lives in Leon Guanajuato. I’ve been trying to call her due to family emergency, However, operators have been unable to assist me. I’ve dialed 011 52 55 and her landline number, which is only 7 numbers. Call can not be completed as dialed. I need HELP!
When dialing to a Mexican landline you should have 10 digits after 011 52 – I understand you only have 9. Have you been able to dial this number in the past? If yes, when was the last time you dialed it?
Have you tried finding your sister online? Does she use a social network? These days it seems to be the most used way to contact someone.
Double checking the area code of Leon – it seems you are using the wrong code. Leon uses 477 and not 55. So you should dial 011 52 477 followed by the 7 digit number (now you have 10 digits after 011 52).
