I am to go on my first trek next month, and I read a lot of people mentioning that taking a walkie-talkie along is a good idea as there is no mobile coverage when going high up trekking. In case you lose your way or go in different directions, it's a good way to keep in contact with the people you are trekking with. From what I know and understand you can not use or own a walkie talkie unless you have a liscense, and I don't want to get into all that paperwork. Is there any license free walkie talkie in India? If yes, please mention which ones they are and the cost if you know.
