To add an international contact's phone number:

1. Go to your phone's address book.
2. When adding the contact's phone number, start by entering a plus sign (+).
3. Enter the country code, followed by the full phone number.
   • Note: A country code is a numerical prefix that needs to 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.

Examples:

• If a contact in the United States (country code "1") has the area code "408" and phone number "555-1234", you'd enter +14085551234.
• If a contact in the United Kingdom (country code "44") has the phone number "07700 900555", you'd remove the leading "0" and enter +447700900555.

Note:

• Make sure to remove any leading 0's or special calling codes.
• If you meant to add a local (in country) phone number instead 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.
