Iridium, Maritime, and Eurostar satellite phones are several international satellite phones that were launched earlier and widely used. Here is an introduction to the use of these satellite phones in international roaming:
1. Introduction to Iridium Satellite Phones:
Iridium Satellite System: The Iridium mobile communication system is the first generation of satellite mobile communication constellation system proposed by the United States in 1987. Each satellite has a mass of about 670 kilograms, a power of 1200 watts, and a three-axis stable structure. Each satellite has 3480 channels and a service life of 5 to 8 years. The biggest technical feature of the Iridium mobile communication system is to achieve global communication through relay between satellites, which is equivalent to moving the ground cellular mobile phone system to the sky.
The Iridium satellite system is a low-orbit satellite constellation, 780 km above the earth's surface, consisting of 66 satellites distributed in 6 polar orbital planes. Each orbital plane has 6 satellites, and there are 9 backup satellites in orbit. Intersatellite links ensure seamless global coverage. Iridium is a satellite communication system that truly covers the entire world (including the North and South Poles). The Iridium satellite system has a low orbit, low latency, low power consumption requirements, and is suitable for mobility.
Satellite phone display:
How to use
1. Select an outdoor location with visible sky, away from buildings and overhead objects, rotate and extend the antenna to a vertical ground position;
2. Long press the power button to turn on the satellite phone.
3. Then the screen will show "SEARCHING" (searching for satellites), and then the screen will show "IRIDIUM" and the signal strength symbol will appear in the upper left corner, and you can talk.
Dialing method (taking Beijing phone number as an example)
1. Iridium calls a landline: 00+86 (China country code)+10+landline number (for example: 00+86+10+8205****); Note: The domestic Beijing area code is 010 International 86+10+number
2. Dial Iridium to call a mobile phone number: 00+86+mobile phone number (for example: 00+86+1380111****);
3. Dial Iridium from a landline: 00+14807682500+12-digit Iridium phone number (for example: 00+14807682500+12-digit Iridium phone number, the landline must have international long-distance access);
4. Dial Iridium from a mobile phone: 00+14807682500+12-digit Iridium phone number (for example: 00+14807682500+12-digit Iridium phone number, the mobile phone must have international long-distance access);
Rates (two-way charges)
International rates are RMB 15-20 per minute
Precautions for use:
1. The insertion and removal of the SIM card must be done when the phone is turned off. To avoid damaging the Iridium phone;
2. Charge the battery after it runs out. It must be fully charged. The battery level is displayed in the upper right corner of the Iridium phone screen;
3. Be careful when the mobile phone antenna rotates to prevent the antenna from being bent. The keyboard flip should be light and steady;
4. Try to use it in open areas, where the signal is better;
5. When using it on a ship, take care to keep it well and put it in a lower and safe place to avoid breaking it when the ship shakes;
6. Each time you use it, please keep the antenna upward and keep a certain distance from your head to reduce the radiation of electromagnetic waves to your head;
II Maritime Satellite Phone
1. Introduction to INMARSAT Maritime Satellite System:
INMARSAT is the leader of the global mobile satellite communication network. It was established as an international organization in 1979 with 89 direct member states. It is headquartered in London and has business all over the world. In 1999, it was transformed into an international commercial company, providing comprehensive maritime, aviation, and land mobile satellite communications and information services. It is the main support system for ship distress safety communications, and is responsible for land emergency communications and disaster relief communications. It is the mobile satellite communication and information system with the best business development and the most advanced technology in the world.
2. INMARSAT Maritime Satellite System M Station (Mini-m, M4) Signal Range: Between 75° South Latitude and 75° North Latitude (excluding the North and South Poles)

Introduction to maritime satellite phone dialing method:
Maritime satellite calling method:
Satellite phone calling satellite phone: 00+Ocean area code+Satellite phone number
Satellite phone calling ground network fixed user phone: 00+Country code+Area code+Fixed user number
Satellite phone calling GSM user mobile phone: 00+Country code+Area code+GSM mobile user number
Ground network user calling satellite phone: 00+874+Satellite phone number
Mobile network calling satellite phone number: 00+874+Satellite phone number
Price standard: RMB 7-8/minute
III. Introduction to Eurostar Satellite Phone
Thuraya satellite system is a commercial satellite communication system. Thuraya Satellite Communications Company is headquartered in Abu Dhabi, United Arab Emirates. Its satellite network covers 110 countries and regions including Europe, North Africa, Central Africa, most of South Africa, the Middle East, Central Asia, South Asia, etc., covering 1/3 of the world. The Eurostar satellite terminal is the world's first smart satellite phone that creatively integrates the three functions of satellite, GSM and GPS, and provides five services: voice, SMS, data (Internet access), fax and GPS positioning. The tariff is divided according to the calling area, with the lowest being less than US$1 per minute. The Thuraya 3 satellite is operated by the United Arab Emirates Thuraya Satellite Communications Company. After it is launched in the future, it will expand the capacity of the Thuraya mobile communication satellite system together with the other two Thuraya l and Thuraya 2 satellites currently in service at the 44° orbit. Thuraya 1/2 satellites were built by Boeing and were successfully launched by Sea Launch in October 2000 and June 2003 respectively. However, this year, Thuraya 3 suffered a load failure and has been discontinued in parts of Asia, and has affected users of Eurostar satellite phones in the southeastern coast of my country.
Thuraya 3 satellite combines a high-power satellite with a ground segment and user handheld devices (mobile phones and other terminals) to provide cellular voice and data services in the coverage area. The ground segment of the Thuraya satellite system includes a ground gateway, a network operation center and satellite control equipment located in the UAE.
Thuraya mobile satellite telecommunications services include: voice (GSM/satellite), 9.6kbps fax, 9.6kbps data, GSM SMS, GPS azimuth determination (accuracy within 100 meters).

Dialing method:
Satellite phone caller
Dialing landline: country code + area code + phone number;
Dialing mobile phone: country code + mobile number.
Satellite phone called
Fixed line to satellite: dial 001 2128133440+IP password +01188216 5208****. Use Shulaya IP phone card to save phone charges (USD1.30/minute); you can also go online and send text messages to Shulaya for communication.
Use 1722 dial-up to the Internet (Shulaya is used as a wireless Mmodem) to check information and send and receive emails; send and receive faxes on the computer, and with the help of a fax machine and a digital-to-analog converter, you can send graphic manuscripts to other ordinary fax machines (add "#" after the fax number).
