​If you are having trouble making phone calls from your Iridium GO! please check the following:

If you are having problems making phone calls from your Iridium GO! and receive the message "This number is no longer in service" or see the number 698 inserted before the country code please check if Captain/Crew Calling has been turned on.

If 'Captain/Crew calling' has been turned on then regardless if you follow the correct dialling sequence, captain/crew calling changes the number and will give the voice recording that the number calling is no longer in service.

To turn off Captain/Crew calling go to the Iridium GO App > settings > Captain/Crew Calling and make sure Enabled is turned off.

​If you are having trouble with people not hearing you when you call from your Iridium GO! please check the following:

1. Is your Iridium GO unit connected to the external Antenna? This makes a big difference, and make sure you are within a few meters of the Iridium GO! to get the best voice quality.
2. Ensure that the microphone is turned on for the Iridium GO! App.
On your mobile device, if it is iPad/ iPhone go to > Settings > scroll down to Iridium Go App > Microphone and ensure that the Microphone is turned on.
If on an Android phone go to > Settings > Apps > Iridium GO! > Permissions and the ensure microphone is turned on.
3. When you are making a call with the Iridium GO! App, ensure that the Mute button hasn't been accidentally clicked. The mute icon is a microphone with a slash through it. It will turn a slightly darker grey when it has been clicked.

Further troubleshooting for Voice calls to and from your Iridium GO!

When receiving a call to your Iridium GO! do you have 5 bars of signal strength?

  1. Make sure your iPhone/Android is connected to the Iridium GO! WiFi.

  2. Ensure you are within 1 to 2 metres of the Iridium GO! when making the call.

  3. Ensure you only have 1 device connected to the Iridium GO! If you have multiple devices trying to use the Iridium GO! connection, this can be a source of issues.

  4. In your Iridium GO! App under Settings > 'Call' make sure +881662990000 is entered, hit save or OK. Select 'Message' make sure the Service Centre number entered is +881662900005 > Save or OK.

  5. Check you have the correct international dialling sequence including country code. For example +1 or 001 for USA, +64 or 0064 for NZ. You can dial the Iridium test number 0014807525105 to make a test call - it’s a free call.

Below are some other generic tips to try if you are having problems connecting the Iridium GO! App to your Iridium GO! device:

  1. We have seen instances where the Bluetooth and cellular connections on a mobile device can interfere with the network connection to the Iridium GO!. Please turn your device into Airplane Mode, then turn on Wi-Fi only. Ensure Bluetooth is turned off. ** This is particularly important on an Android device.**

  2. Check the Wi-Fi of your device is paired with the Iridium GO! - not another network. If paired correctly it should show Iridium - XXXX Connected on an iPad/ iPhone and on Android Wi-Fi if paired correctly it should show Iridium - XXXX 'Connected- No internet'

  3. Turn off or uninstall any Ad Blocker or virus protection Apps running on your device.

  4. Turn off, but ideally uninstall VPN Apps. Uninstalling any VPN is preferred, as we have seen VPN Apps override your earlier choice to turn it OFF in the settings. If you uninstall a VPN you will need to do a full restart of the device and Iridium GO! before attempting to connect again.

  5. Ensure you only have 1 device accessing the Iridium GO!, If you have multiple devices trying to use the Iridium GO! connection this can be a source of the issue.

  6. On an iPad/iPhone please go to your iOS settings > Wifi > Click on Iridium-XXXXX. At the bottom select HTTP Proxy and click on the "Off" button.

  7. On an iPad/ iPhone that has upgraded to iOS14, ensure 'Local Network' is turned on. Go to your device Settings > Scroll down the page until you see the Iridium GO! App > Open the App Settings > Turn ON Local Network.

  8. On your iPad/ iPhone iridium GO! App if you get the error message 'Could not connect to the Iridium GO!, please check the IP address and Wifi connection' Go to your iPad/ iPhone device > Settings > Privacy and Security > Local Network > Iridium GO! App > Turn on Local Network for the Iridium GO! App.

If you are able to dial out from Iridium GO! normally, however, at the receiver's end their phone does not ring, test calling another cell number. It is possible the receiver's network provider blocks satellite calls.
