Essential Apps and Connectivity
While you’re on a Panch Prayag Yatra tour package from Delhi, don't expect 5G everywhere. BSNL and Airtel generally have the best coverage in the Garhwal region. It’s a good idea to download offline maps of the Uttarakhand area before you leave Delhi. Also, keep a few UPI apps ready, but always carry some physical cash. Many small shops in the higher reaches might have network issues with digital payments. Being a little "old school" with your prep will save you a lot of hassle.
