how do I call 01-800 number in Mexico from Canada? I have tried:
011-52-800-plus the seven digits
011-52-01-800-plus the seven digits
011-52-1-800-plus the seven digits
but they cannot get connected.
The correct way to dial is 011 52 800… However, a (Mexican) toll free number is generally used for domestic calls only. Often these numbers can not be called from abroad. The entity you want to call should also have a regular number you can call.
