We have an Inmarsat Mini-M Tracphone50 (KVH) with big antenna for sale. It's an old system, but still working (more info about the coverage and satellites via the link below).
Mini M has voice, fax and data (2.4 kbps). The transceiver and handle are rather new, the antenna is original.
We have used this for voice calls and email.
Price 2000 euros.
If you know anyone, who would be interested, let me know!
