What is the Japanese mobile phone system?

Are you sure you want to go to Japan to buy a mobile phone for Sharp?

If that's the case, I'm sorry to tell you that it can't be changed to Chinese system.

Because that machine has no Chinese font.

Only 902 903 703 Sharp machine can brush Chinese.

There is not even a 705 (many 705s sold by Taobao now are actually the motherboard of the Hong Kong version 633 with a 705 shell).

I guarantee that all other Sharp mobile phones in Japan can't be replaced by those in China.
