MORE HAM IN A CAN? (Kunming Airport)

I SWITCHED on my mobile phone - almost in dread. "CHN-CUGSM" appeared on my screen. Hmm, that sound's positive.

My phone beeped :(

WELCOME TO CHINA AND USE CHINA UNICOM's NETWORK, PLEASE DIAL + FOR INTERNATIONAL CALL/SMS. ENJOY YOUR JOURNEY IN CHINA.

I didn't know whether or not to salute in response.
