Why can't telecom mobile phones receive short messages in Japan?

If you can't receive SMS in Japan, you must first determine the local network situation, whether there is a 2.3.4G network, and whether the mobile phone supports 4G networks. If you don't support 4G network, you may not receive SMS in Japan, because many foreign 2, 3 G networks have been disconnected.
