Submission + - Everest has permanent 3G connection to the summit (geek.com)
From today that changes. Ncell, the Nepalese subsidiary of Swedish carrier TeliaSonera, has completed the installation of a high-altitude 3G base station at 5,200 meters. The good news for climbers is that the station will provide a signal even at the highest point of 8,848 meters.
With the introduction of 3G, communication on the famous mountain is now a lot easier. You can just take your standard smartphone with you and dial home when you reach the top. If no one believes you’ve made it then just make a video call instead and show them. More importantly, if you get into difficulties while climbing it’s a lot easier and more reliable to call for help.
