Which is better, DoCoMo or Softbank?

In terms of signal and quality, DoCoMo is the oldest mobile phone company in Japan, and its price belongs to NTT. But if all your classmates and friends use Softbank, you can also use it to contact each other with the phone number of the club. Morning 1, 9: 00 pm is free. If your language is not good, it is cheaper to use Softbank when you start reading a language. If you change to AU or DoCoMo after graduation, that's another matter. It's better than DoCoMo, but the quality of electrical appliances sold in Japan is not bad. Softbank can last for two years. Nowadays, international students can't hand in their mobile phones once a month. Don't choose the one that is too cheap, so the phone bill is about 20 thousand. My 920sh still has a few hundred dollars a month, but that's all.
