Travel to Japan, can I use China's mobile card and Unicom's mobile phone to travel to Japan?

Domestic mobile or Unicom mobile phones, whether 2G or 3G cards, need international roaming to be used in Japan (including GSM), otherwise there is no signal.

The domestic voltage in Japan is 1 10V, and ordinary domestic mobile phone chargers and notebook power adapters can be directly used (the voltage adaptation range of domestic chargers is 1 10V ~ 240V).

Please go to China Mobile or China Unicom's online business hall for details or telephone consultation.
