Communication facilities during the trek can vary widely. While mobile phone services are available throughout Nepal, including at Everest Base Camp, the quality of reception differs by location. The main communication technologies used on the trails are NTC and Ncell SIM cards, though their coverage is inconsistent. Some trails may have no service, while popular routes often provide Wi-Fi. To ensure reliable contact when necessary, the Nepal Sanctuary Treks team carries a satellite phone or portable communication device.
