How to add international contacts' phone numbers

To add an international contact's phone number:

Open your phone's address book.
When adding the contact's phone number, start by entering a plus sign (+).
Enter the country code, followed by the full phone number.
- Note: A country code is a numerical prefix that must be entered before the full national phone number to make a call to another country. You can search online to find the country code you need.

For example, if a contact in the United States (country code "1") has the area code "408" and phone number "XXX-XXXX", you'd enter +1 408 XXX XXXX.

Make sure to remove any leading 0s or special calling codes.
If you meant to add a local (in country) phone number to your phone's address book, enter the number as if you were calling your contact on the phone.
All phone numbers in Argentina (country code "54") should have a "9" between the country code and area code. The prefix "15" must be removed so the final number will have 13 digits total: +54 9 XXX XXX XXXX
Phone numbers in Mexico (country code "52") need to have "1" after "+52", even if they're Nextel numbers.
