In June 2019 I landed for the second time in Nepal when I attended the Himalayan Travel Mart in Kathmandu. Being online is part of my job and buying a Nepal sim card at Kathmandu Airport on arrival was one of my first priorities. But to find out about the best sim card in Nepal for tourists I also researched the mobile network in Nepal, all the prices for the available prepaid sim cards, where to buy them and what to bring. In this article I tell you everything I found out and you should know for your next trip to Nepal.
