The free Iridium GO! App is used to make voice phone calls, SMS Messaging, and SOS functionality. It is available on Apple (iPhone/ iPad) and Android devices.
Quick Start Guide
Activation of Iridium GO!
To activate your SIM card please go to: PredictWind Satellite Portal
You will need to use your SIM card number when the package arrives, and the IMEI number on your actual Iridium GO unit itself. In the activation process, you will select your airtime plan, and must enter your credit card details for the airtime charges.
The activation process will be complete within 10 minutes.
Please note the billing of your Iridium GO plan is pro-rated so you can choose to activate your Sim card at any time during the month, and will only pay for that portion of the monthly charge.
After completing the activation process you will need to insert the SIM card into the Iridium GO device. Remove the battery with a flat head screwdriver, or a coin. Slide the SIM card holder toward the hinges, and lift to open, insert the SIM card into the slot. Close the cardholder and slide it away from the hinges to lock it. Then install the battery. Make sure the gold battery contacts are facing down over the 4 connector contacts. Replace the battery cover. Next charge the battery, open the USB cover and firmly plug in the USB cable. Connect the supplied USB cable to a USB outlet on your boat. If no USB outlet is available you can temporarily use the car charger. We recommend leaving the unit permanently on charge. Next plug in the external antenna, by carefully but firmly to “click in” the adaptor. The small co-axial cable should not be bent at a 90 degree angle, as it may damage the cable and affect the signal strength.
Turn the device on by raising the swivel antenna into the upright position. Make sure the antenna has a clear view of the open sky and horizon.
Once raised the device will automatically complete the power-up sequence in approximately 1 minute, and will begin registration with the Iridium network. Once registered the LED light will turn green, and the signal strength icon will appear on the screen. If the SIM card has not been activated, no signal strength will be shown. If you have two SIM cards ordered please check you have the correct SIM card inserted.
Download the App
Download the free 'Iridium GO!' App from the App Store or Google Play. This App manages your connection to the GO! and allows you to make phone calls, send text messages, and has SOS functions.
Your smartphone or tablet device MUST be connected via Wi-Fi to the Iridium GO! in order for the Iridium GO! App to operate. Please turn ON Airplane/flight mode then on your iOS or Android device, connect to the wireless network created by your Iridium GO. It will look something like 'IRIDIUM-xxxxxx.' No password is required. Also ensure all devices have Bluetooth capability turned OFF to avoid networking connectivity issues.
Other Wifi networks can be an issue as your device 'searches' and connects to the best Wifi signal. You may need to forget other networks so it does not try to connect to say your home/marina Wifi.

Satellite phone calls are not included in this allowance. When you use the PredictWind Offshore App connected to the Iridium GO, it will display how many voice minutes you have used.
Although voice mail can be used on the Iridium GO! we do not recommend using this service. To retrieve voice mail messages you will be charged the standard Iridium GO! calling rates US$1.09/min.

Friends/family can send you free text messages from https://www.predictwind.com/iridium-free-sms/

internal dialing sequence in order to connect calls: '+' [Country Code] [Phone
SMS Text Messaging
When messaging, enter the international dialling sequence of the intended recipient: '+' [Country Code] [Phone Number]. SMS messages are limited to 1000 characters.
Twitter does not currently work with Iridium. Twitter, for an unknown reason, has removed Iridium as a supported mobile carrier, even though they still list Iridium as supported on their website https://help.twitter.com/en/using-twitter/supported-mobile-carriers . Iridium are aware of this issue and are working diligently to get in touch with Twitter and find a resolution.
The Iridium GO! offers a programmable SOS button that can be configured to notify specified contacts in the case of an emergency. Once configured, an SOS can be initiated either from the Iridium GO! device or application. An SOS initiated by pressing the SOS button on the Iridium GO! device will only send an emergency message with location information, while an SOS initiated from the Iridium GO! application will also provide the option for two-way voice communication with the designated contact.
WARNING! In order for the Iridium GO to send an SOS emergency message to a designated Call Recipient and Message Recipient, you must configure the SOS settings in the Iridium GO before leaving the port.
Failure to configure the SOS button will result in no message being sent when the SOS button is pressed. This could prevent or delay an emergency response and result in serious injury or death.
The number you use must be a trusted family member or friend, DO NOT add the local Coast Guard or Marine Rescue service. That is what your EPIRB is for!
The number you use must be capable of receiving SMS messages (a cellular phone).
The number you use needs to include the full international dialling sequence, for example, +1 (USA), +61 (AU), +44 (UK)...
NOTE! The SOS setup is related to your SIM card. So if you deactivate the service and get a new SIM card you will need to register the GEOS service again.
GEOS safety services: To support the SOS feature, Iridium has contracted with GEOS Travel Safety Group to provide an emergency response coordination service for your Iridium GO! at no additional charge. These services are offered and are provided exclusively by GEOS and not by Iridium which is a separate, unrelated company.
Setting up the GEOS service
Register at https://my-geos.com/account/devices/new from your computer. To register, you will need your Iridium phone number and Iridium GO! IMEI (located on the Help > About page in the Iridium App).
On the Iridium GO App go to Settings > SOS > GEOS Service and select ‘Use,’ and enter the 5-digit authorization code provided by GEOS in their registration confirmation email, then Submit. The 5-digit code can also be found on your GEOS registration page at the bottom left-hand corner. If successful, your SOS settings will appear and the SOS action will be set to Call and Message, for the GEOS service.
You may then choose to add additional emergency message contacts (see Message Recipient, below). The Message action enables automatic Emergency SMS alerts to be sent at 5-minute intervals until cancelled.
The Call and Message action enables the message feature as well as an automatic phone call to your designated call recipient when SOS is initiated from the Iridium GO! application. Call Recipient: Enter the number for your Call Recipient. It is important that the number is entered in the correct international format with the international access code (+ or 00), country code, and phone number for proper routing.
Spoken Language: Select the spoken language of the emergency response personnel.

This can be done via the GEOS website https://my-geos.com/login or by contacting GEOS directly at https://www.geosresponse.com/contact-us.html NB: Each Iridium GO unit will receive its own unique 5-digit authorization code.
Testing the SOS GEOS safety service
We recommend testing the SOS setting on your device. GEOS asks that all tests be scheduled at least 72 hours in advance unless otherwise approved for an earlier test time by the Operations Team.
You will need to contact GEOS directly at https://www.geosresponse.com/contact-us.html and request a Test Request form and email it back to firstname.lastname@example.org A member of the GEOS Operations Team will then confirm the time that you have requested and answer any further questions you might have about the test.
