🔍 Key Concepts

• Dialing format differences between Iridium and Inmarsat systems • International dialing prefixes used for satellite phone networks (e.g., 00 + country/network codes) • Typical Inmarsat mobile numbers (IMN) structure and which leading digits identify Inmarsat vs other satellite systems

💭 Think About

• Look at each choice and ask: which one follows a realistic pattern for calling an Inmarsat ship terminal from another satellite network? • Compare the first 4–5 digits of each option: which prefixes are known for Inmarsat vs Iridium vs other networks? • Think about whether the ship being 300 miles west of San Francisco affects the number you dial or only affects coverage/satellite visibility.

✅ Before You Answer

• Verify which digit strings (like +870, 00870, 008816, etc.) are associated with Inmarsat mobile numbers in your study materials or FCC/ITU tables • Confirm whether the Iridium terminal requires you to use an international access code (00) plus the Inmarsat network code, or a different pattern • Check that the option you choose does not contain symbols or formats that the Iridium keypad would reject or that are not used in standard satellite dialing (e.g., stray plus signs at the end).
