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.
Our recommendation
In mountainous regions of China, an Iridium phone is the better choice because, due to the topography, a clear line of sight to the Thuraya or Inmarsat satellites is not always guaranteed. The western part of China still has Thuraya coverage, but the eastern part does not.
Terms and Conditions of Entry and Use
For latest requirements for entry and usage in China, we strongly recommend contacting Chinese consulates or embassies before your trip.
