I am in Caoxin Road, Huaqiao, Kunshan. If I am trapped in Shanghai, is this a roaming?

Not really. I live in Hongtu International, next to Waiqingsong Highway. After many months of verification, I live in Shanghai Overseas Chinese Business Circle every day. I don't roam when I make a phone call there. Although I will receive a roaming package reminder, it doesn't matter because there is no roaming, because it is a bit embarrassing there. Signals from both cities can be received, but the two sides have reached an agreement that the number segment at the edge will be automatically transferred to which city it belongs to.
