For MobileConnect in Marketing Cloud Engagement, you can send only to data extensions whose mobile numbers include a locale. Review this list to ensure that your locales are valid. Include a locale with each mobile number as part of the Phone field in your source file when you import contacts to your data extension. Imported locales are converted to upper-case letters. Upper-case and lower-case letters are allowed for SMS sending.
