Q: enable wifi calling China Unicom iPhone 5s

I have an iPhone 5s, and I have upgraded to the latest iOS. I am considering switching to T-Mobile if the wifi call works. However, I cannot find the wifi call option in my settings. It seems that wifi calling is illegal in China. I currently use AT&T. Will the wifi-calling menu magically appear when I switch to T-Mobile?

iPhone 5s, iOS 8.2
