FAQs

Iridium

Example 1: If you are calling from a landline or cell phone in the United States to an Iridium satellite phone, dial 011-8816-XXX-XXXXX. In this instance, it doesn’t matter where the satellite phone is located, as long as the landline is based in the U.S. You probably recognize the International Direct Dial (IDD) access code for the United States, which is 011. 8816 XXX XXXXX is the Mobile Station International Subscriber Directory Number (MSISDN), which is used to identify the mobile phone number internationally.

Example 2: If you are calling from a landline or cell phone outside of the Unites States to an Iridium satellite phone, dial the IDD access code for the country you are in, then the MSISDN. For example, if you are calling from a landline phone in Germany, you would dial 00-8816-XXX-XXXXX. The IDD access code for Europe, and many other countries, is 00. Note that this not the country code. 8816-XXX-XXXXX is the Mobile Station International Subscriber Directory Number (MSISDN), which is used to identify the mobile phone number internationally.

An important consideration is that Iridium satellite phones need to have a direct line-of-sight to a satellite to function. Do not attempt to use an Iridium phone near an obstruction or in a building. You can use the Iridium network to make and receive calls all over the globe, including the polar regions.

Example 1: If you are using the Iridium satellite phone to call a landline or cell phone in the United States, dial 00-1-XXX-XXX-XXXX. Regardless of where the satellite phone is located, this is the procedure for calling a landline in the U.S. 00 is for all outbound calls from your satellite phone, 1 is the U.S.’s country code, then the area code, then the seven-digit phone number.

Example 2: If you are using an Iridium satellite phone to call a landline or cell phone in a country outside the United States, dial 00-CC-XXXXXX. Regardless of where the satellite phone is located, this is the procedure for calling a landline outside of the U.S. 00 is for all outbound calls from your satellite phone, CC is for country code, and XXXXXX is the actual number.

Example 3: If you are using an Iridium satellite phone to call another Iridium satellite phone, dial
00-8816-XXX-XXXXX. Regardless of where the satellite phone making or receiving the call is located, this is the procedure for calling between Iridium satellite phones. 00 is for all outbound calls from your satellite phone, 8816 is the MSISDN, and XXX XXXX is the actual number.

Any Iridium subscriber using Iridium voice service within the 50 United States, District of Columbia, Puerto Rico, and the U.S. Virgin Islands can use the emergency 9-1-1 system.

However, outside the U.S. and its territories, a 9-1-1 call will not be directed to an emergency call center. Your call will terminate to a message instructing you to hang up and dial the local emergency provider directly. For this reason, it’s important to keep a list of emergency phone numbers and important numbers for each country you travel in.

If you are asked to enter a PIN code when you turn on your Iridium satellite phone, it means your SIM card is protected by a PIN code. The default PIN for all Iridium phones is 1111. To keep your phone and account secure against unauthorized use we recommend you set up a new PIN code for your SIM card.
If the incorrect PIN to an Iridium satellite phone is entered three times in a row, the phone will automatically block the SIM card. To unlock it, enter **05** and press the green button. The phone will instruct you to enter the eight-digit PUK1 code and press the green button. Then you will be able to set up a new PIN.

The PUK1 code is sent to you via email when you activate your SIM card. If you cannot find your PUK1 code, please contact Remote Satellite Systems.

Iridium voice mail can be accessed by pressing the Voicemail icon in the Menu or calling 011-8816-6299-0000

Choice 1: Voice Call
Dial 2888 from your Iridium handheld device. This free call will connect you with an automated system that will notify you of the number of remaining minutes of calls to cell phones and landlines you have left as well as the number of days to your account expiration. The announcement will be in English.

Choice 2: SMS
Using your Iridium phone, create a blank text message and send it to 2888 (or 002888 or +2888). You will get a response to this free message with the number of remaining minutes of calls to cell phones and landlines, the number of days to your account expiration, and the expiration date. The reply text message will be in English.

Choice 3: Voice Call
When you place any phone call with your Iridium phone, the remaining minutes will be announced before your call is connected.

Inmarsat

Every call that originates from an ISAT phone is considered an international call. For people who haven’t made an international call before, it can be a little tricky. This guide will explain how to make calls using an ISAT phone. Each ISAT terminal is given a 9 digit international telephone number in addition to a 3 digit country code. All ISAT phones use the country code 870.

If you are using your ISAT phone to call a landline or cell phone in the United States, dial the appropriate country code (001), then the area code, and the phone number. If the phone does not begin to dial, try pressing the pound (#) key to complete the number and begin dialing.

Example 1: 001 408 808 8838 #
You can see in the example the U.S. country code (001), the area code (805), the number (808 8838), and the pound key (#). Sometimes the pound key is necessary to alert Inmarsat that you are done inputting the phone number.

If you are using your ISAT phone to call a landline or cell phone in a different country, dial the country code and the full phone number. You can find the international country codes here. Note that it does not matter where the ISAT phone is located, just where the call destination is.

You can use any phone on the planet to call an ISAT phone. If you do not know your personal ISAT phone number you can reference your Quick Reference Guide provided to you or contact Remote Satellite Systems at 888-989-8199

If you are calling the ISAT phone from the United States, regardless of where the ISAT phone is, dial 011, Inmarsat’s country code of 870, then the 9 digit ISAT phone number. 870 is the country code for all Inmarsat phones.

Example 1: Dialing an ISAT phone from the United States 011 870 737009141

From inside the United States, the first numbers will always be 011. If originating a call from outside the U.S., please use this tool to help you find the correct number sequence. Note again, it does not matter where the ISAT phone is located.

Example 2: Dialing an ISAT phone from outside the United States: 00 870 737009141

When calling a ISAT phone from outside the United States, you will use the same formula of XX (in this case 00), Inmarsat’s country code (870), and the ISAT 9 digit phone number (737009141). Every country is different, but many countries use 00. You can use this tool to figure out what code to start with. You can also always ask the operator for assistance connecting you. As long as you know the 870 country code for Inmarsat and the ISAT phone number, the operator can connect you.

It’s important to remember that the ISAT account will not be charged for incoming calls, however the caller will pay for satellite ISAT phone rates. Some phone providers block international calling, and others charge various rates. If you are going to call an Inmarsat phone number, ask your phone provider for the international call rate to 870 and if there are any international plans available.

Iridium Troubleshooting

Because all Iridium phone numbers are international, it can be very expensive to make calls to an Iridium phone and many phone providers will block international calls unless the subscriber has an international calling plan.
To work around this, Two-Stage Dialing lets callers in the United States and Canada call a local number (based in Phoenix, Arizona) that can connect you with an Iridium phone. The Iridium subscriber is responsible for the cost of the call.  
To place a call to an Iridium subscriber or to receive a call on your Iridium device using Two-Stage Dialing, the subscriber must make an outbound call and successfully place the call for the first time. Call Iridium’s automated test number at (408) 752-5105 for free. After an outbound call has gone through, the Iridium subscriber line will be registered for Two-Stage Dialing and future calls will be routed correctly.
If the initial outbound call was dialed successfully and Two-Stage Dialing is still not functioning properly, please contact Remote Satellite Systems technical support at (888) 989-8199.
Perhaps you have previously used the Iridium Two-Stage Dialing system to receive calls. Now it’s not working. What happened?
The Iridium service outage that took place on October 20, 2016 cancelled all Two-Stage Dialing subscribers.  All subscribers who use the service, even if you were previously enrolled, must establish an outbound call. Call Iridium’s automated test number at (408) 752-5105 for free. After an outbound call has gone through, the Iridium subscriber line will be registered for Two-Stage Dialing and future calls will be routed correctly.
If your new Iridium SAT phone displays “Enter Phone PIN” when you turn it on, enter numbers 1111 followed by the green call key. If the PIN code does not work, do not try repeatedly. If you enter the wrong PIN code 3 or more times it will lock the phone and you will need the sim cards PUK code to unlock it. Call Remote Satellite Systems technical support at (888) 989-8199 with assistance in getting your satellite phone operational again.
