Critical IsatPhone Pro Firmware Upgrade

Inmarsat has just released a Mandatory firmware upgrade meaning that the features introduced by the firmware are vitally important for the GSPS service including the network and your IsatPhone Pro handset.

Inmarsat has advised us that this upgrade is absolutely critical as IsatPhone Pro phones that are not upgraded by 30th of June, 2013, will no longer be able to register on to the satellite network and make/receive calls.

What firmware version am I using?

    How does this apply to me: Maureen J. Seikaly, in Salt Lake City? Do I have this phone? Haven’t used my intern’l phone since April 2012. Probably will only use it once per year. What is the column on left (fLike, Tweet, in, inshare) it gets in the way of reading page, no “x” to close it. very irritating to a non twitter person like me

      This does not apply to you Maureen. This only applies if you have a Satellite Phone.

      As for the column on the left, it allows the article to be shared. Apologies if this obscures your view.
