3. Use after changing the network environment and time period, and you can also compare other mobile phones (using the same network) to see if this phenomenon exists, if it also exists, it may be caused by the poor signal coverage of your local network operator. For example, some tall buildings, basements, parking lots, remote mountainous areas, etc. can affect the mobile phone signal.

There is no signal on the BBK mobile phone because the signal will be affected by various factors such as terrain, landform, and high-rise buildings during the propagation process, 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 back on and off and try again;

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

3.Check to see if other Unicom users around you have a signal;

If there is no signal, you can contact human customer service for feedback.

Hello! There are two reasons for signal instability: network reasons and mobile phone reasons.

1) Good signal (signal indication full): You may encounter network peak hours (holidays or weekdays at night 20:00 22:00), this time period is due to the busy network, the connection rate is relatively low, and it takes multiple calls to get through.

This is the type of phenomenon that requires you to avoid calls during peak network hours**.

2) Bad or unstable signal: Indicated by the signal indicator bar on the left side of the mobile phone screen. When the signal is boosted, the indicator bar increases, and when the signal is weakened, the indicator bar decreases.

For example, in high-rise cities, supermarkets, and underground shopping malls, due to the signal and shielding effect of reinforced concrete buildings, and the attenuation of signals by the geographical environment in mountainous areas, it is easy to have bad or unstable signals.

In this case, please move your mobile phone slightly, or walk out of the building to ensure that the signal is good (not blocked or attenuated, and then dial**.

3) Specific network environment: If you continue to experience insufficient signal in a specific area, it may be because the network coverage there is insufficient. Your network operator or service provider** can provide you with more information about your network coverage.

4) The other party's mobile phone has set up the call restriction function, the other party's mobile phone is faulty, or the network environment of the other party's mobile phone is not good.

This phenomenon requires contact with the other party to confirm the other party's situation.

5) Caused by abnormal mobile phone network due to QQ hanging in the background, surfing the Internet, etc.

If it is caused by this reason, it can be restored by turning it on and off once.

If you are sure that it is a problem with your mobile phone, not a problem with the network, you can send your mobile phone to the BBK after-sales service center for testing. You can find it in the toolbox of the mobile phone menu after-sales service or our mobile phone**.

In the process of propagation, electromagnetic waves will be affected by various factors such as topography, landform, high-rise buildings, climate, etc., so that only a very weak signal can be received in a certain range, such as the basement of some floors, the first and second floors can not receive the signal, which is a very normal phenomenon. This phenomenon can be solved by increasing the density of the base station and increasing the coverage of the base station. Since the construction of the project requires a process, please be patient.

Do you mean to receive a mobile network signal or a wifi network signal? If it is a mobile network signal, it may be because the environment you are in is too closed, resulting in poor signal quality received by the mobile phone, we recommend that you try the following methods to solve the problem:

1. Shut down and restart to try it;

2. Take out the SIM card and reinsert it or replace it with another SIM card.

3. Use it after changing the network environment and time period, and you can also compare other mobile phones (using the same network) to see if this phenomenon exists.

If the wifi network signal is not good, it may be that the wifi itself is relatively slow, or it may be that your mobile phone is too far away from the router, it is recommended that you try the following methods to solve the problem:

1. Try to connect to the router at close range.

2. Restart the router, or restore the router to factory settings to re-encrypt the wifi.

3. Change the wifi connection in other places.

1. Change the network environment: the mobile phone is in some tall buildings, basements, parking lots, etc., which will affect the signal; If you are in a closed place (e.g., an elevator) or in a remote area, it is easier to disconnect your phone from the outside world.

2. Re-register the network: You can restart the mobile phone to let the mobile phone re-register the network.

3. Determine whether the SIM card is valid: If the SIM card is not installed properly, or the SIM card is damaged, the signal will inevitably be affected. You can remove the SIM card and reinstall it, or try a different SIM card.

4. Operator network problems: If the signal of the mobile phone suddenly deteriorates within a certain period of time, it may be a network problem of the operator. It is recommended to compare mobile phones with the same carrier SIM card in the same environment to see if there is the same situation, and you can try it at another time period.

5. Whether to use a metal protective case: The metal protective case will have a certain impact on the mobile phone signal. It is recommended to remove the metal case, replace the factory mobile phone case to protect the phone, and then observe and use it.

2. The wifi signal is weak for a short time, you can try to restart the phone and change the time connection;

3. For router reasons, please try to connect to other wifi for comparison;
