Just called, the number you dialed can't be connected for the time being, and the incoming message will be notified to the other party by SMS. What happened?

1. There is no signal on the other party's mobile phone. If the mobile phone you dialed can't receive the signal temporarily, this prompt tone will appear when calling the other party's mobile phone system at this time.

2. The other party has set up call forwarding, and he has also set up call forwarding. Call forwarding can be set to temporarily unavailable or closed! Call forwarding is set, and all numbers cannot be dialed in! If the call forwarding number set by the other party is normal, you can get through! Of course, some software can also do this.

The other party took out the SIM card without turning it off. If the owner forcibly takes out the SIM card without turning off the phone, this prompt tone will appear when you call the other party because the owner information cannot be searched.

4. It may be that there is no signal at the other party's location and you can't answer the phone.

There are obstructions, the building density is high, and the call quality is most closely related to the call environment. In places with complex structures such as buildings, these locations usually belong to areas where communication signals are seriously blocked. Why the signal strength of mobile phones varies greatly in different rooms on the same floor is also related to signal occlusion. The intensity of signal reception is mainly related to the distance from the base station. The closer the distance, the stronger the signal will be, and if the signal meets a wall, it will weaken.

If the room is just opposite the base station and there are many walls or obstacles on the side facing the base station, this will happen even on the same floor. At the same time, the closer the building layout, the worse the signal reception may be.

5, temporarily unable to connect should mean that the called mobile phone is not in the service area or abnormally turned off, in short, there is no way to contact the other party. For example, if the other party doesn't want to answer the phone, the principle is to turn to an empty number or a power-off number, or blacklist the calling party to hear total recall. However, the blacklist is mainly automatically intercepted by the software, and there will still be a connected sound before the prompt tone is heard.

6. The other party has set the Do Not Disturb mode.

The settings in the mobile phone may give the caller an "illusion" of poor call signal. Some citizens have reported that when dialing different people's mobile phones in different places and at different times, there will be such a situation: after the first call, the receiver prompts that "the other party is temporarily unable to connect", and when dialing again, the phone will be connected normally.

This situation is not caused by bad signal. It is because many users set up "do not disturb mode" in their mobile phones in order to filter out harassing calls or not to disturb incoming calls, text messages and notifications of various apps when they don't want to be disturbed.
