As mentioned in the doc - "Currently, SMS messages can be sent to and received from United States phone numbers. Phone numbers located in other geographies are not yet supported by Communication Services SMS. For more information, see Phone number types.

Also, ensure that the phone numbers should be provided in E.164 international standard format (e.g.: +14255550123). The From phone number may be a Short Code as well (e.g.: 23456).
