IsatPhone Pro Firmware Upgrade – v.5.3.0

New firmware update is available for download from with immediate effect.

The new firmware version 5.3.0 fixes a fault with versions 5.1.0 and 5.2.0 that causes the battery not to charge when turned off, affecting a limited number of IsatPhone Pro handsets shipped after 7 September 2012.

This is a mandatory firmware upgrade. It supersedes version 5.2.0, which had a deadline for mandatory update of 30 June 2013.  Given the replacement of firmware version 5.2.0 with 5.3.0, the upgrade deadline has been extended to 31 December 2013.

Inmarsat recommends that customers upgrade their phones to version 5.3.0 or higher at the earliest opportunity (or 5.2.0 or higher for handsets shipped before 7 September 2012).
All phones must upgrade by the extended deadline of 31 December 2013 or the user will experience problems connecting to the network.

Why do we work with the company GESAT mbH!

Already since 1999, while our “Red Earth Expedition” – “7.000 km on foot and by camel through Australia’s Outback,” we report online in our blog. Through regular and reliable transmission the blog was called up to 43.000 times a month. Today it is not an impossible challenge any more for a report from the center of a desert, 1,000 kilometers away from all human civilization or in the middle of the isolated jungle. Quite the contrary, it had already become a reliable and affordable reality to operate diary online, maintain a website and keep contact with the outside world sometimes in emergency.

During our expeditions, we use the satellite modem “Inmarsat BGAN Explorer 300” of GESAT.

The BGAN 300 is only 1.3 kg, fit just in every jacket pocket with his Din A5 size and is also very user-friendly. Phone calls, faxes, SMS, Internet access and e-mail are easily doable with this little device.
Our documentation work only works reliably if we have a ruggedized outdoor laptop. The brand new GESATBOOK 301 for us is the optimal choice. With its body case made of a magnesium-aluminum alloy, it is very robust and weighs only 2.5 kg. It is shock and water resistant, has a sunlight-readable display, a built-in GPS receiver, DVD drive and much more. For us GESATBOOK 301 means the support column of the documentation and is therefore one of the most important equipment of our expeditions.
For transmission, the BGAN EXPLORER 300 is associated with the GESATBOOK 301 (plug and play). Once the satellite modem has been connected to a satellite, we can send our experiences written down, this time pictures, in the ether just like sending a regular e-mail and also make them on our homepage.
Since 1999 we have been working with GESAT in the communication area. The GESAT is a national and international operating engineering company with many business areas. Undoubtedly the center of excellence in satellite communications in German-speaking, we are very glad such a reliable partner at our side.
Here we would like to express our heartfelt thanks to Mr. Hubert Einetter for the long-term, uncomplicated, professional and friendly cooperation.
