I was there in 2023.

You're describing exactly the opposite of what I found to be the facts on the ground. My connection to a residential address in the United States was allowed for a couple of days at a hostel, then blocked. It was never allowed over (Chinese) mobile data.

But it was completely fine over the internet service to my apartment. The home internet service and the mobile service were provided by the same company in a bundled plan. I was always curious what they were doing.
