What is the coverage of Unicom's 3G signal in Aiqiao Village, Guishan Township, Macheng City? Is there a 3G signal in this place?

Just returned to Sichuan by k696 from Shanghai, passing through Macheng. I don't know the place you are talking about, but there is no 3g signal at the railway station, and to my surprise, there are no stations passing through several cities in Hubei. What is even more surprising is that there is an edge signal that doesn't even exist in Suzhou (when surfing the Internet). Telecom coverage all the way is really good.
