Now, there are some misconceptions when it comes to satellite cell phones and when you are able to use them. First not all satellite telephone networks have international coverage. Actually, there is certainly only a single which has true pole-to-pole coverage, and that is Iridium.
Inmarsat has in following ideal having a worldwide network except that of polar regions. But, however, Inmarsat does not have a handheld sat telephone that would perform in its network! Inmarsat's only handheld phone at the moment works inside so-called SPS network, with has quite a lot restricted network (parts of Africa, Asia as well as the Indian Ocean). The worldwide I4 network might be employed through (pretty expensive and big) BGAN terminals. Inmarsat has announced even though that it is going to release a handheld mobile phone (ISatePhone Pro) by mid 2010, which will deliver the results inside I4 international network.
Then there's Globalstar, which covers most continents (but not oceans), but has difficulties of its own. It began owning technical issues with its satellites, and will probably be capable to fix the concern by replacing the satellites not earlier than late 2010, or even mid 2011.
The 4th significant player at the moment is Thuraya, which covers Europe, Asia, Australia and North Africa.
So, while satellite mobile phones do offer a good service allowing you to possess connectivity in remote locations, you might find your self switching concerning mobile phones, when planning to diverse areas with the globe.
And lastly, there is certainly one far more critical thing to remember. Satellite cell phones will not operate indoors. Properly, a minimum of not having unique enabler and exterior antenna. And there's an identical concern with using them in cars. The phone's antenna merely needs clear access to the sky to perform correctly.
Worldwide? Yes. Everywhere? Well, not completely, not yet.
