Satellite phones have become increasingly popular in recent years, particularly among business users who need to stay connected while traveling in remote areas. India is home to a growing number of satellite phone users, thanks to the increasing availability of affordable handsets and service plans. Satellite phones work by using a network of orbiting satellites to relay signals, meaning that they can be used even in areas where there is no cellular coverage. For travelers who may otherwise be shut off from contact, this makes them a necessary tool. There are a number of different satellite phone providers operating in India, offering a variety of plans and tariffs to suit different needs. However, all satellite phones require a clear line of sight to the sky in order to function, so they may not be suitable for use in densely populated areas or indoors.
