I was just about to buy a new smartphone when I mentioned going to China, and the guy at Carphone Warehouse said 'Android phones purchased here (UK) tend not to work on the Chinese network' I guess this is something like the past having to get a 'dual band' phone if using it in the USA. That was easier ecause the packaging on the phone would say 'dual band'. Is there an equivalent wording I should look for? Or some kind of special phone? I know I-phones have global compatibility but they're twice the price!
