Hi Mike , yes all 3 work in China as well as qq which I always use talking to my other half in shenyang or just finding each other at the airports , funny how things work when I went to China in December I thought my phone would not work , but as I stepped off the plane my phone rang and it was my lawn mower man wanting to cut my lawn here in Melbourne ha ha ,Okay I said but you will have to wait to get paid , she also has qq on her smart phone so she is contactable anytime , we only use Yahoo for emailing which at her end goes to her QQ email box anyway , most of the girls are way ahead of us with their use of modern electronics , regards Sujuan and Robert .
