What to do if iphone6s has a bad signal The solution to a poor signal on Apple 6s mobile phones

1. If there is no signal or the signal is poor when the mobile phone is inserted into the Unicom card, it may be due to other objective conditions. Because the signal will be affected by various factors such as topography, landform, and tall buildings during propagation, if you are in a relatively closed place, the signal will be affected. Here's how to deal with it:

Turn the phone back on and off and try again;

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

Check whether the signals of other Unicom users around you are normal.

2. If it still cannot be used normally after self-service troubleshooting, it is recommended that you contact the local manual customer service for verification and processing.

Software issues.

First of all, you need to confirm that you are currently in the dead zone of the mobile ** signal. Due to the mobile network coverage, there are some places where there will be a signal blind spot, and no matter what mobile phone it is, the signal will be bad, so it is necessary to rule out this problem first.

If it's not a dead zone, no matter where the signal is poor, you can try to reset the network settings on your iPhone. First, open the Settings app on your iPhone, as shown in the image.

In the settings list, find the [General] column and click to enter.

In the restore list, please click the [Reset Network Settings] column, this operation will not affect the personal data on the phone, so please feel free to operate.

If you have a passcode on your iPhone, you will need to enter it before you can continue.

Then click the [Reset Network Settings] pop-up at the bottom to confirm to start the restoration. After the restore is successful, see if the signal on your iPhone6s improves.

Also, if you currently have a new iOS system version, please upgrade to the latest version in time. It can be detected in [Settings - General - Software Update].

In addition, if the system prompts you to upgrade the operator's network configuration file, please update it in time. Because of the latest carrier profiles, mobile** and network optimizations are made.

END hardware failure.

If the above software problems are eliminated one by one, you can see if it is a hardware problem. First of all, you can try to take out the ** card, and then install it back to see if it can solve the problem. Of course, you can also choose to change to a different ** card to see what the situation is.

Step to read. If changing the card can't solve the problem, and the signal is still very poor, it is enough to say that the iPhone hardware is faulty. At this time, you can only bring your mobile phone and go to Apple's after-sales service for testing.

First, there are two reasons for the poor network signal and no service, the operator problem and the user's own setting problem, but due to the SIM card, it is temporarily impossible to pass the test of its own replacement.

Second, if it is due to your own settings, it is recommended to restore the network settings.

Third, if it is a problem with the operator, it is recommended to call**operator customer service**: China Unicom 10010, China Mobile 10086 Telecom's customer service** are all 10000, feedback, ask the relevant departments to verify whether it is a local network problem, and go to the business hall to test the SIM card.

Fourth, if the reason for the operator is ruled out, then it is a problem with the mobile phone, and it is recommended to contact the iPhone after-sales service in time to negotiate and solve it.

Generally speaking, the iPhone will automatically connect to the corresponding network according to the user's mobile phone card. However, sometimes when the signal is not good, there will be a situation where the mobile phone network cannot be found, so you can try to manually select the network. Here's how:

In the first step, in the Settings app, tap to go to the "Carrier" option.

Step 2: On the carrier options page, turn off the "Automatic" function. In the third step, the network operator will be displayed later, and the user only needs to select the corresponding carrier according to his mobile phone card. For example, China Mobile users can select "China Mobile".
