The Japanese version of iPhone5 was upgraded to 7.0.4 two days ago. After adding +86 to the phone number, you can make a phone call and receive a short message, but you can't send it out.

It's simple. This is the problem with the Japanese edition. The number of phone calls and text messages is different. Because the operator is from Japan, you have to add 86. Otherwise, it's an international call, and texting is not allowed. The easiest way is to download the number assistant and save two numbers. This is what you should be able to do at present. Otherwise, you can crack it or escape from prison. Now you can escape from prison at 7 o'clock.
