Zhuhai-Macao mobile signal difference

China Mobile has no base station in Macau, so the signal difference is normal. In Macau, only three operators, CTM, Hutchison and SmartCom, have base stations, so the signal of China Mobile will be better near Guanzha Square, or in Taipa's high-rise residential building, because the mainland antenna will come over the mountain, and the signal in other places is poor or not, so it is normal for Singapore and Portugal to have no signal.
