Jobra is the last place where the network is available. It also does not have a stable connection so it’s better to leave all your worries and enjoy this beautiful trek.

You must take a guide with you unless you are a professional & seasoned trekker in the Himalayas. It is especially easy to get lost in the woods in the Himalayas and not know left from right! So, it is better to take a local villager or a guide who will not only show you the path but also save you in the bad weather conditions. 

There is not electricity throughout the trek. The only place you’ll find a plug to charge your phone or camera batteries will be Manali before and after the trek.

Therefore use your electronic equipment wisely. Fully charge your batteries before leaving your hotel and use your electronic equipment minimally.
