+52 Being added to contacts
I live in Mexico, and it is not necessary to dial the country code (+52) in order to call either a land line or a mobile phone. In fact, Mexico is set up for 10-digit dialing, and has been for several years. Yet for a number of my contacts, the number is actually being changed, and then the call does not go through. I can edit the contact numbers and yet it reappears. Telcel is my carrier.
