Backup Satellite Internet service in Africa?

toy4two writes: I am faced with replacing an aging VSAT (Very Small Aperture Terminal) satellite system sitting in the middle of nowhere in some jungle in Africa. With most VSAT installations, if the satellite link fails we have some way of reaching the equipment by terrestrial VPN, cellular, or PTSN dial-up modem from here in the United States. None of the typical out of band access methods exists in this part of Africa. I have been looking at various satellite options to use as out of band access (on different birds than our VSAT network) and have come up with Regional BGAN (R-BGAN), BGAN, and Iridium flavors like OpenPort. However, most seem geared towards news reporters or road warriors and require a laptop and human intervention to establish the data connection. All we need is a low bandwidth option to telnet into an Ethernet switch several times a year if the VSAT modem needs to be rebooted or new settings applied. Is there any technologies out there that can be dropped on site, always on, and require no user intervention on site to reach?
