Via DEMOS, a report about mobile devices :
“Since 1993, Hong Kong residents have been able to use their mobiles throughout the entire underground system.Why is this still not possible in Britain? Back in 1999, a spokesperson from one UK network cited differences in mobile etiquette between Europeans and Asians, adding that some people found it annoying to hear only one side of a conversation in a packed tube train. Perhaps but arguably it is even more annoying not to be able to receive messages or transport information while stuck on a stationary train.”
