The above information refers in each case to the center of the country / region.
For Thuraya and Inmarsat we have indicated the elevation angle to the satellite and the azimuth. The flatter the satellite is above the horizon, the more difficult the reception will be depending on topography and buildings. This should clarify our classification. For fixed installations, the elevation angle is not crucial as long as the antenna has a clear view to the satellite.
Iridium has orbiting satellites. Here the proximity to the equator plays the decisive role, because at the equator the satellite density of the Iridium network is lowest. On the sea, however, this is negligible because there is a clear view all around, even to satellites located flat above the horizon.
Himalayan region
Although the topography is difficult, the Himalayan region is well suited for Thuraya phones because the satellite is high above the horizon. The satellite is located in the south-east or south-west, so coverage shadows are only to be expected if you climb a mountain on the north side.
To avoid possible coverage gaps due to the topography, you can of course take an Iridium phone with you. You're more likely to have to deal with disconnects, but you also know that it will be working again a few minutes later.
Using IsatPhone in Nepal
Starting in Juli 2017 we got the information from customers that their IsatPhones were not able to connect to the network in some regions. Obviously this is blocked. A registration failed in the region Pokhara and in Chitwan National Park. So we cannot recommend the usage of IsatPhone in Nepal at the moment.
