The Iridium Mail App is an email service that works with the Iridium GO! However, you will notice on the Play store this app only has a 2 star rating which evidence of the customer experience. For this reason, we have developed the PredictMail service, which allows you to use your existing favourite pop3 email client offshore. Unfortuntately due to the ongoing bugs and support issues with the Iridium Mail App, we no longer support this App.

Iridium Mail Setup Instructions: NOTE: This app is no longer supported by PredictWind

This Iridium Mail & Web App provides email access over the Iridium network. The email feature allows you to register for one or more email accounts, that may be used like any email account.

1) Download the Iridium Mail & Web App

Download and install the ‘Iridium Mail & Web’ App and the 'XWeb Satellite' App. At this time we also recommend installing the 'PredictWind Offshore App' from the Google Play Store onto your smartphone or tablet.

2) Register for an Iridium Email Account

Go to the link to fill out the registration form, follow the instructions and register for a username and password. Select ‘Iridium Subscriber' from the device selection drop-down menu in the registration form. Registration for an account is free and required to use the application. Make sure you have activated a SIM card and have your Iridium phone number as it is required to register for email.

Please note your username becomes your email address. For example, if johnsmith is your username, your Iridium email address would be

The alternative username is required in case the initial username you request is not available.

Your password for the Iridium Mail & Web App must be between 6-18 characters, upper and lower case letters are allowed, numbers are allowed, and only the following punctuation marks are allowed. , ? ! ; : - _ () {} [] “ ‘

The email field at the bottom is for Iridium to send to you confirmation of the registration process by email (please check spam/promotional folders if you do not receive the confirmation). This email address should be your normal land-based personal address (Gmail/outlook/yahoo/etc).

The Iridium email address is not associated with your SIM card, so if you do get a new SIM card you do not need to register again. However if your account is inactive for 12 months the email address is removed from the Iridium system and you will need to re register.

Note: All your emails are saved locally on the device, if you delete the App at any time you will lose the email data with it. These emails cannot be recovered.

3) Connect your Android™ Device to the Iridium GO! WiFi

  • Flip-up the antenna on Iridium GO! to turn it on.

  • Wait for Iridium GO! to initialize and establish a connection with the Iridium network.

  • On your Android™ device, Turn off Bluetooth, Place in Flight mode, go to the Wi-Fi setting and select the ‘Iridium-xxxx’ network. Wait for your device to connect to the Iridium GO! Wi-Fi network.

  • NOTE: On some Android devices If you see the words "Internet may not be available" this is normal.

4) Set up the App

Open the Iridium Mail & Web App. You will be asked to enter your full name, username, and password, used during the registration process. Leave the "Reply To" field blank. Now you are ready to send and receive email with your Iridium email address. This method is simple and recommended to minimize your email traffic.

Go to Settings > Connection, Please make sure it is set to Iridium GO! for mobile devices. Please do not change any of the other default settings on the Connection setting page.

5) Using the App

Composing Email ( You do not need to be connected to the Iridium GO to compose emails)

  • From the Main menu, tap the Mail icon, then Email. Then tap on the envelope symbol to compose your email.

  • Tap 'To' and enter the recipient's email address. Tap 'Subject' and enter the subject of the email. Tap 'Message text' to enter the body of the email message.

  • When your email is complete tap the Arrowhead symbol top right this will move the email to the Spool folder. You can compose as many emails as you like, the emails to be sent will sit in the Spool folder until your next Iridium Mail connection.

Sending/Receiving Email

  • You must be connected to the Iridium GO! Wi-Fi.

  • From the Main menu select Mail > Select Send/Receive Email. When you see 5 or 4 bars of signal strength Tap 'Send/Receive Email.' The session log window will show the progress of the connection. During the connection all items in the Spool folder will be uploaded to the Iridium Mail server for distribution. When the session is complete you will see 'connection closed' in the session log. Please see the screenshot below.

  • Select Email > then select 3 dots bottom right > folders. Select Sent

    It will show sent emails.

  • If the connection terminates prematurely during a data transfer, the email that was not uploaded will be stored in Mail > Email > Outbox. Once connected again, the mid-file restart feature will pick up the transfer of the email at the point where the file dropped during the previous connection.

6) Configure Web Browsing (Text Based Websites Only)

The 'Iridium Mail & Web' App allows you to view text-only web pages using the XWeb web browser. Please download XWeb from the Play Store.

It should be noted Android 10 and above no longer works with XWeb

Most websites are now running Https instead of Http, these changes have had implications for the usability of XWeb.

  1. Connect your Android device to the Iridium GO WiFi - First select flight mode, then connect to the Iridium GO WiFi.

  2. Open the Iridium Mail & Web App to ensure you have valid account information then click on the ‘Web’ icon on the home screen.

  4. Wait for a 5 bar signal strength. Select GO To XWeb it will then go through the dialing process. You will be directed to the XWeb App.

  5. Continue to access Web (text-based) content. Test by selecting BBC > News. This site is correctly configured. Any drop in signal strength (less than 5) will make the download extremely slow and may terminate. If you leave a page inactive for a few minutes, the connection will be dropped, and you will not be able to view any other text-based web pages, you will need to start the process again.

  6. Click the Iridium Mail & Web App to close the data connection. It will automatically close.
