You can use the “+” symbol in place of “011” if dialing from a cell phone. The “+” sign is usually the same key as “0” on a smartphone's keypad. Some countries share a country code. For example, Canada, the United States, some places in the Caribbean, and Guam share “1” as a country code.

There might be an error in what you typed. Check whether the phone number is in the right format, which is + (country code) (region code, if applicable) phone number. You must use this format for both domestic and international phone numbers.

Officially, all calls to US numbers begin with a “+1” because that is the region code for North America and the Caribbean (technically, the North American Numbering Plan or NANP). That's why your phone displays a “1” before the number; it really is part of the number.

Do I need to prefix +1 to the mobile numbers before sending an SMS? No, number formatting does not matter. The SMS will be sent even if you do not prefix the country code unless you are not sending messages outside the country.

The Importance of Country Codes The US country code phone number format is +1 X, where the Xs represent the area code, central office code, and line number respectively. Knowing the correct format for including the country code is essential for making successful international calls.

You should provide the complete number, including the country code with no use of special characters or spaces. Just the number. For example, a phone number like +1-555-555-1212 should be formatted as 15555551212 .

The plus-sign indicated that the user may have to dial another prefix per local dialing conventions in the country of origin that selects a trunk for international network access; the digits immediately following are thus the country code, where 1 is the NANP country code.
