We’ve been looking at satellite phones for a project in a hot place far from normal coverage. The best we’ve found so far is the Thrane & Thrane TT-3080A which has worldwide coverage through Inmarsat, and can do single-channel ISDN data transfer. The only problem, according to the very helpful sales guy at Satphone.co.uk, is that we’ll have to get our order in quickly “as we only have limited numbers of them and they are very popular with journalists going to the Middle East.”
