Are there Wi-Fi and mobile network facilities available during the Upper Mustang Trek?

Communication in Upper Mustang is relatively good compared to the deep gorges of the Annapurna region, thanks to the flat desert terrain that allows better signal transmission. A local SIM card is essential for reliable mobile service. Nepal Telecom (NTC) provides the best coverage, offering decent 3G and sometimes 4G in major hubs like Jomsom, Kagbeni, and Lo Manthang.

Ncell works in Jomsom and Kagbeni but often weakens or disappears deeper into the restricted area toward Charang and Lo Manthang. Expect signal drops at high passes such as Nyi La or Lo La and in narrow canyons.

Most teahouses along the main circuit offer Wi-Fi, typically costing NPR 200–500 ($1.50–$4 USD) for 24 hours.
