Unicom 3G 186 signal, okay? I am in Xiamen. If I go back to my hometown in Guizhou, is there a signal?

I used the number 3G 186 in Qiandongnan, Guizhou, and there was a signal, because Unicom's 3G 186 signal was the best among the three operators. Where there is no 3G signal, you will automatically switch to the 2G network or enjoy the 3G policy of 0. 15 yuan to make all calls for free.
