Comprehensive and Detailed Explanation:
The correct answers are B and D.
* B - The Mobile Number field must be Text type in MobileConnect and include country code (e.g., +1
555-555-5555).
* D - A Phone type field is necessary to validate and standardize mobile number formats inside MobileConnect.
Both fields are used for identifying recipients during MobileConnect sends.
#Why others are wrong:
* A and C: Locale fields are used for language/country preferences, not required for MobileConnect message sending.
