I travel frequently to Mexico. When in Mexico, the phone numbers are the same 10-digits as in the U.S., but the phone system does not recognize the preceding +1. For example, if you want to call someone in San Francisco, you can dial 415-555-1234. If the phone automatically adds the 1 (1-415-555-1234), the call still goes through fine. In Mexico, I have contacts in my contact list that have a phone number such as 624-555-1234. When I access them from my contact list, Android automatically adds the 1, dialing 1-624-555-1234. Unfortunately, this doesn't work in Mexico. I need to dial just the 10 digits. How do I stop Android from automatically adding the +1? If I want the +1 I will add it to my contacts myself. There is a feature called Assisted Dialing (or something similar) that I thought would control this, but I turned it off and it continues to add the leading 1 automatically. Any ideas? Thank you!
