Why can I send a short message to a stopped mobile phone number without prompting the other party that it has stopped?

The text message was sent by my mobile phone. Your mobile phone has a phone bill, so you can send it out. If it stops, you won't receive the short message.

It is very likely that the other party is a smart phone, installed software similar to mobile phone housekeeper and 360 mobile phone security guard, and set up white list interception. The intercepted message is "The number you dialed is out of service". It is also possible that the other party has set a spoof ringtone, and the music of the ringtone is "The number you dialed is out of service" and so on.

The situation of the other party's downtime:

1. Generally speaking, you can still receive text messages within 24 hours after the phone is turned off, and others can also receive signals when they call, but you can't send text messages or dial the phone number at this time. Of course, if it is an emergency, such as calling the police, it is also possible.

If you don't pay in time after 24 hours, you won't get the text message or the phone call. This is when someone calls himself, he will receive the message that the other party's phone has stopped, and sending a short message will also display the message that sending failed.

3, the mobile phone is not sold until it is shut down for three months. In these three months, the mobile phone has no function and can only connect to wifi. Other functions can not be used, which will bring trouble to people; Some operators will also charge a subscription fee when the mobile phone is down (5 yuan for one month), and deduct it directly from the phone bill when the phone bill is available.
