Let's see for yourself,!Find a place with a signal. Wish.

1. There is no signal or the signal is relatively poor, mainly because the signal will be affected by various factors such as terrain, landform, and high-rise buildings in the process of propagation, such as the current location is in a relatively closed place, and the signal may be affected.

2. If the mobile phone signal of other China Unicom users is normal, the following methods can be used to troubleshoot:

Method 1] Turn on airplane mode, then turn off or restart your phone and try again.

Method 2] Test of changing the phone card to change the mobile phone card to the mobile phone of a family member or friend and try again.

The signal will be affected by various factors such as topography, landform, tall buildings, etc., and if you are in a relatively closed place, the signal will be affected. Here's how to deal with it:

1. Turn the phone on and off again;

2. Swap the SIM card to a family member's or friend's phone and try again;

3. Check whether other Unicom users around you can use it normally.

1. See if your current location is in the signal blind zone, which includes outside the network coverage area, such as workshops, factories, suburbs, rural areas and other places where network communication facilities have not yet been built, as well as places where urban signal mobile phones are shielded and blocked by signals that cannot be covered, such as office buildings, bars, private rooms, elevators, underground places, buildings, etc.

Solution: Step out of a field where there may be no signal and dial ** in a wide area.

2. If there is no problem with the location, it may be caused by interference facilities, and the mobile phone receives the signal through the propagation of electromagnetic waves, so the base station establishes a connection between the transmission of radio waves and the mobile phone, so as to achieve the purpose of voice call. Interference from electromagnetic waves can affect mobile phone signals, which usually occurs in the test room.

Solution: Find the surrounding signal interference equipment, turn it off or remove it.

3. Temporary failures may occur when the network is particularly busy, which will also have a certain impact on the mobile phone signal. For example, in the bustling business district, there will often be a situation where you can't get out, and others can't get in, especially during peak hours, and there are often delays in commuting and holidays.

2) The degree of network coverage of operators varies according to different regions, and urban areas basically meet the coverage, but some remote areas may have insufficient coverage capacity, which will lead to no signal on mobile phones.

You can determine whether the current regional network coverage is poor by whether the mobile phone has no signal when it is only in the same area, or whether there is no signal from nearby mobile phones using the same carrier** card.
