To break into a phone contact, the recommended method is to:

- **Say your call sign once** (Correct Answer: B)

### Explanation:

1. **Why the correct answer is correct:**
   - Saying your call sign once is the most efficient and courteous way to indicate your presence and desire to join the conversation. It follows standard operating procedures and is easily understood by other operators.

2. **Why the other choices are incorrect:**
   - **A: Say “QRZ” several times, followed by your call sign**
     - "QRZ" is used to ask "Who is calling me?" and is not appropriate for breaking into an ongoing conversation.
   - **C: Say “Breaker Breaker”**
     - "Breaker Breaker" is not a recognized or appropriate method in amateur radio for joining a conversation. It is more commonly associated with CB radio.

### Rules of Thumb:

- Always be polite and concise when attempting to join a conversation.
- Use standard operating procedures to ensure clear communication and avoid confusion.
