The operational changes to the network are currently scheduled for November 28th, 2014, so make sure you upgrade your firmware soon if you still have an older firmware running on your IsatPhone Pro - otherwise you could find yourself without a working satellite phone.  You can check if you have the latest version on your IsatPhone Pro, by going to **Menu** > **Settings** > **About** > **Firmware version**. Please note that the Inmarsat firmware update tool is for Windows systems only. Please [contact us](http://www.globalmarinenet.com/contact-support.php) for information regarding upgrading on Mac or Linux machines.  ![](https://static.hubspot.com/final/img/content/email-template-images/placeholder_200x200.png) ### Subscribe Email ### Popular Stories [Pivotel International is now Pulsar](https://blog.pulsarbeyond.com/pivotel-is-now-pulsar) May 09, 2024 [Global Marine Networks (GMN) is now Pivotel.com.
