British climber Rod Baber has allegedly set the record for the highest-ever land-based mobile-phone call and text message. The call was made from 8,848m on the highest peak of Mount Everest at 5.37am on Monday. Baber was using a Motorola MOTO Z8 handset.
Reception on Everest is possible as a base station in China has line-of-sight with the mountain's north ridge. Communications links have also been improved by the fact that a climbing team from the Chinese army is planning to take the Olympic Torch to the top of Everest.
