I just returned from 8 days in Mexico. I have the Nationwide + Mexico plan on Verizon. To call the US from Mexico, you have to dial a 001+AC+number. I was unable to find a way to automatically have the phone put the 001 in as a prefix. Therefore, I had to dial all of the numbers e.g., 001-123-456-7890. Does anyone know a way to have the default prefix be something other than 1?
