What is the reason for the poor signal of the Apple mobile phone

The signal difference may be caused by the baseband version.

Why is the iPhone signal poor? Here's why, you'll never be wrong when buying a phone!

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 reasons are: poor surrounding network, network setting problems, SIM card problems, system software problems, and mobile phone hardware problems.

1. The surrounding network is poor.

The network of the surrounding environment is relatively poor, which will lead to the signal being in a state of no service, which will lead to no signal and no service on the Apple mobile phone, and changing a place with a good network can solve the problem.

2. Network setting problems.

After the iPhone has been used for a long time, the phone will suddenly have no signal and cannot connect to the network due to some reasons of the system itself, you can solve the problem of no service by restoring the network settings and restoring to the default factory settings, or by restarting the phone.

3. SIM card problem.

A problem with the SIM card of the mobile phone will also cause the mobile phone to be unable to connect to the network. You can take out the SIM card, check whether it is damaged or worn, or find another SIM card to insert into the Apple mobile phone to try to solve the problem, but if it still can't be solved, you can deny the reason for the SIM card.

4. System software problems.

Due to some vulnerabilities in the iOS system of Apple mobile phones, these vulnerabilities sometimes cause the mobile phone to be unable to search the network and display no service status, you can update your mobile phone's system to the latest version to solve this problem.

5. Mobile phone hardware problems.

If the above methods can't solve this problem, there is a high probability that there is a problem with the hardware of the mobile phone, and you need to go to Apple after-sales service to request processing.

Question: Apple will get stuck after a few years.

Question: Can the Apple mobile phone still receive a single signal**?

Does the Apple 12 Pro Max last for five years.

Does the Apple 12 Pro Max last for five years.

The 12Pro Max can be used for about five years under no special circumstances.

1. Because it is easy to damage the chip or poor contact with a large card to cut a small card, this situation needs to be replaced with an Apple special card.

2. Sometimes it is caused by the mobile phone being infected with a virus, which needs to be disinfected by the mobile phone.

3. Because the metal shell has the disadvantage of weakening the signal, this situation needs to remove the self-equipped metal protective shell.

4. If the transmitter or power amplifier fails, you need to replace the mobile phone transmitter or replace the power amplifier.

5. Due to network failure, you need to ask the operator's customer service to refresh the network.

6. The signal is poor due to some setting changes, in this case, you need to directly restore all the settings in the original mobile phone.

Precautions for the use of Apple mobile phones:

1. The protection of the camera is mainly in the process of using the camera function, and we must pay attention to the dust and dust proof of the camera. At the same time, when taking pictures, be sure to fix the phone in your hand well to prevent the phone from slipping. As for the protection of the screen, the most basic point is to protect the same as the case, do not put the phone with the keys or the like.

2. Don't expose your iPhone to high temperatures or cold, like dog days in July and August, don't expose your phone to the sun; Or take it to an air-conditioned room and put it in a place where the air conditioner blows directly. When charging, it's normal for the battery to get a little hot, but don't let it go directly to a high temperature.

It may be due to a location that is too closed or remote (basement, elevator, etc.).

Carrier issues, which make the signal and network fluctuate greatly.

The mobile phone antenna is damaged, and the ability to receive signals is weak.

The back cover of the Apple phone is a metal back cover, which will also affect the reception of the signal.

The communication module is damaged.

If the mobile phone signal is good and bad, it may be because of the operator, don't worry about the failure of the mobile phone, if the mobile phone has been in a weak signal, it is recommended that you change the place of use, if the signal is not good in other locations, it may be that the mobile phone antenna is damaged or other hardware problems, it is recommended that you bring the purchase voucher and after-sales agreement to the after-sales point for testing.

0The signal of Apple mobile phones is indeed weaker than that of some Android mobile phones, because of the structure and accessories of the mobile phone, if the signal is very poor, it may be caused by hardware damage or environmental reasons.

Hello! Poor mobile signal is a common phenomenon in Apple mobile phones, but it basically exists in 4, 4s, and 5Above, I will tell you directly after seeing that you have to answer with others, in the case that your mobile phone card is confirmed to be reissued, not the old card that has been cut, if it is in the urban area, and not stairs, elevators, underground parking lots, the signal is still very unstable, very poor, if you are licensed goods directly take the warranty card invoice to the maintenance station to ask for warranty, and tell the maintenance station, redo the system and other methods have been tried, or so, ask for warranty!

It's a problem with the built-in antenna,iphone4The signal is transmitted by a circle of metal around it,If you hold it directly on the bare metal, it is easy to cause a bad signal because there is an electrolyte in your hand,So it is recommended to add a protective case after purchase

The iPhone has two basebands, and the Intel baseband signal will be slightly worse.

Why is the iPhone signal poor? Here's why, you'll never be wrong when buying a phone!

1.Damage to the SIM card leads to no service due to inability to read the SIM card, 2The hardware failure of the mobile phone leads to the inability to read the SIM card resulting in no service, 3

Software conflict resulting in inability to read the SIM card resulting in no service, 4There is no signal coverage in the area, resulting in no service.

5.It is recommended to bring the device to a regular after-sales center for repair, so as to avoid problems such as damage to the motherboard caused by damage to the mobile phone card slot.

First, the iPhone can't type**, and it can't be connected** for the following reasons:

1. iPhone network settings are incorrect.

2. There is a problem with the SIM card.

3. The signal of the network operator is unstable.

4. iPhone system failure or hardware failure.

Second, the general treatment method:

1. First check whether the signal is not good, it is best to use a friend's iPhone, try to change the card, and eliminate the problem of the card.

2. If the card is fine, it is recommended to restore the iPhone network settings to try, and open the settings of iPhone6 in turn--General--Restore--Reset Network Settings.

3. Dial 112 without a card, try a few more times, it can explain that it is a problem with the operator or card, or it may be improper settings or software conflicts, upgrade to the system or restore the system; If you can't get through 112, it's a problem with your mobile phone, and you can go to after-sales maintenance.

From a technical point of view, the main reason for the poor signal of the iPhone is closely related to the baseband. Apple's mobile phone has used Intel's baseband since the iPhone 7, but it has not solved the problem of poor iPhone mobile phone signal, and Apple's mobile phone has alleviated this problem by optimizing software.

In addition, the mobile phone signal has a great relationship with the antenna design of the mobile phone. From 2G to 5G, the antenna design in mobile phones is becoming more and more complex. There are only a few antennas in 3G mobile phones, while there are dozens of antennas in 5G mobile phones, which is complex and difficult.

And Apple has not had a good solution to deal with this problem. In particular, the iPhone XS adopts a dual-SIM dual-standby design, and many users often report that the phone often has no signal. To today's iphone11 series mobile phones, some netizens also report that the mobile phone signal is not good.

There are many reasons for poor signals, such as mutual interference between the four antennas, as well as the amount of mobile phone materials and antenna space holding.

First, the cause of the failure:

1. Network problems or network inability to cover.

When the network coverage is not good, it is generally located in mountainous areas, basements, elevators, and when there is shielding or signal interference, there will be no signal or very weak. In the process of debugging, optimization and maintenance, the network may also cause signal instability, and the general network will return to normal, and the mobile phone signal will return to normal.

2. Problems with the mobile phone itself.

There may be a problem with your phone's receiver. You need to go to the repair point to have a look. Of course, the factor of SIM card corruption cannot be ruled out.

2. Solution:

1. Choose a high ground to use your mobile phone.

When the signal is not good in the place, you may wish to go to a higher position and use it in a place where the window is biased, and many can solve the problem of poor mobile phone signal.

2. Switch between different mobile phone networks.

When using a mobile network, when the signal is not good, friends with conditions may wish to use Telecom or Unicom card, so that in many cases the problem of poor mobile phone signal can be resolved.

3. Mobile phone signal amplifier to enhance mobile phone signal.

A cell phone signal amplifier can amplify the surrounding cell phone signal, which can improve the quality of the network. It is very practical for users in some of the lower residential areas, basements.
