What to do if the iPhone 4s does not catch the network. No network, search, or why the iPhone does not see the operator's SIM card.

Quite often, iPhone owners, after changing iOS, repairing the phone, or a long period of inactivity, encounter the problem of the network disappearing on the device. Why is my iPhone not picking up the network? We will talk about this further.

Wrong date and time settings

Most often, the cause of the malfunction is the incorrectly set time, as well as the time zone. Therefore, in the case when the iPhone does not catch the network, first of all, you should look for a discrepancy in the set date and time. If the phone really shows the wrong date, for the appearance of the network it will be enough to carry out such simple steps:

  1. You need to connect your smartphone to an active Wi-Fi network.
  2. Enter the phone settings, open the "General" section and go to the "Date and time" item.
  3. Set the line "Automatically" to the active position (if the default state is set, you just need to turn it off and then on again).

Airplane mode

Actually there is a large number of reasons why an apple phone can search for a network, but not see it. The most common will be discussed below in the text.
If you receive a "No network" error when correct settings date and time, do the following:

  1. First of all, you need to turn on, and after a few moments turn off the Airplane mode again.
  2. If this does not help, you can simply restart your smartphone.
  3. Also, it is recommended to remove the SIM card to make sure it is branded and original. In addition, you should look for any mechanical damage on it.
  4. After that, you need to place the SIM card inside the device, enable / disable the Airplane mode a couple of times, after which the connection should resume.


If these actions did not lead to changes, you need to check the settings mobile operator without forgetting updates. You need to establish a connection to Wi-Fi, then go to the basic settings of the mobile device, open the "About this device" line. Provided that the smartphone needs updates, the OS will automatically issue a request to install them. If Wi-Fi does not work on the phone, the iPhone must be connected to iTunes, after which the device should be updated to the most new version iOS.

What to do if there is no network after unlocking?

In most cases with the problem in question iPhone owners found after unlocking using a program called Ultrasn0w or a firmware update. Also, such a problem may appear as a result of restoring, updating, activating or deactivating the smartphone using Redsn0w, SAM tool, or after jailbreak.


You can try troubleshooting "No network" in iPhone smartphone after factory unlocking, using your own IMEI number for this. In general, such a problem is practically not dangerous when compared with notifications about a problematic or unsupported SIM card.
Provided that a notification about the absence of a network appears, it is safe to say that the phone accepts a SIM card, but it does not see either an ordinary network or an Euroset.

The easiest and fastest way, which very often helps to fix the problem, is to reset the network settings. The subscriber should insert an unsupported SIM card, go to "Settings", then open the "General" section, go to the "Reset" section and select "Reset network settings".
You can also try to back up and delete all data, but such actions can have a bad effect on the functioning of the device.

What should I do if the problem appeared after using the SAMPrefs or Redsn0w programs?

The considered method of troubleshooting provides a positive result in 90% of cases:

  • You need to place a non-AT / T SIM card inside the iPhone and then connect the smartphone to iTunes using a USB cable.
  • After the phone is detected by the program, you need to back up, and then click "Restore".
  • It's best to try to restore the phone first without using the Shift/Option buttons. You can also restore the gadget in DFU mode.
  • You need to wait for the restoration process to complete, after which 2 iTunes functions will be opened.
  • Restore from backup.
  • “Operate iPhone like new” - it is recommended to select this item.
  • Next comes the proposal for the passage of activation. In this case, you need to use a non-AT/T SIM card and wait for the required signal.

When nothing helped, you need to continue looking for solutions and repeat all steps, from the first to the fourth.

Other reasons

Often, customers trying to cut a SIM card for a new iPhone become hostages of an error due to which the smartphone is not able to recognize the card. To solve such an error, you need to order a SIM card from a personal provider.


It happens that the connected provider does not provide services in that area - as a result of this, the "apple" smartphone knocks out the "no network" error when searching for it. It also happens that the card is simply not activated. In this case, you need to contact your provider for help.

Often the problem "No network" occurs due to a malfunction of the antenna. Under this condition, you should seek the advice of professionals and preferably an Apple store, where specialists will help you set up an ordinary network, as well as the Euroset.

Today, cellular communication has a huge coverage area. However, it also happens that the iPhone writes “no network”. What to do in this case? It depends on several factors:

  • Weak mobile signal
  • Technical malfunction

Why does the iPhone 6 not catch the network, and what are the solutions?

  1. The absence of a signal may be due to errors in the operating system. Often you just need to check that the date and time settings are correct. It happens that the reason lies precisely in this.
  2. If the first point did not fix the situation, then try updating the OS to latest version, or vice versa roll back to an older one.

Did the first two options help?

Most likely, the task is more difficult than it seems. If there is no network on the iPhone 6, the problem is in the health of the gadget filling or the SIM card.

  • Remove and reinsert the SIM card or ask your carrier to replace it with a new one.
  • If this does not help, then the problem is in the health of the motherboard or antenna. Open the "General" -\u003e "About this device" item in the settings. Below should be IMEI number (serial number devices). Its absence indicates a malfunction of the motherboard.
  • IMEI in place? In this case, the reason most likely lies in the operation of the antenna. You need to replace it in the service center with a working one.

Radio module repair

No signal cellular communication may be due to the failure of the radio module. Consider the main reasons for the violation of its functioning.

  • As the device is used, dust and dirt accumulate in it. All this negatively affects the operation of microcircuits.
  • When moisture enters, the radio components are oxidized, which causes a breakdown.
  • Far often, the network on the iPhone disappears after a fall or mechanical impact.

Antenna replacement


As a rule, if an antenna breaks down, it cannot be repaired, so it cannot be repaired. There is only one way out - to replace.

  1. Disabling the display module
  2. Disconnecting loops
  3. Removing the battery, vibration motor, motherboard, camera and headphone jack

Only after all this is it possible to gain access to the antenna. The entire replacement procedure usually takes no more than 30 minutes. It should also be noted that all components are small in size and very sensitive to mechanical damage.

How to determine your gadget model?

Often, the order either does not indicate the model of the device at all, or is indicated incorrectly. As a result, technicians have to refine this information themselves. This leads to additional loss of time, which is disadvantageous for you and us.

Meanwhile, it is very easy to find out the model of the gadget. First, it is listed in technical documentation, but, as practice shows, the instructions are not saved by everyone. Secondly, this information is indicated on the body of the device.

Mobile phones and tablets

You need to remove the back cover and the battery. The full model name will be indicated on the inner panel. On some, the covers are fixed, so the information is applied in small print on the back of the case. You can also see the model name in the settings - information about the phone (tablet)

laptops

Turn the laptop over, there should be a barcode sticker on the bottom cover. It usually indicates the modification of the device.

Monoblocks

pay attention to back panel monitor

Cameras

Most often, information is placed on the upper front side of the device. It is also duplicated in the lower part near the battery latch, but with a serial number and a barcode

Camcorders

Examine the inside of the battery cover or the compartment itself. For waterproof cameras, the model is indicated on the inside of the USB plug

Navigators

Look for a sticker or inscription on the back of the case

Important! The model must be specified in full, up to the last letter/number. Keep in mind that some gadgets of the same company have different product lines. For example, Acer laptops have lineups Aspire, Extensa, TravelMate, etc. It would be correct to indicate Acer Aspire V3-331-P7J8, not Aspire V3-331-P7J8, and even more so not just Acer Aspire. In the latter case, you simply designate a model line, which includes dozens of modifications.






Often, after a fall, flashing or updating the phone, as well as replacing the SIM card, the smartphone does not catch the network. The inscription “no network” appears and, in fact, the device turns into a useless expensive “brick”. There are usually several reasons for this problem. Let's look at the most common of them, while paying attention to ways to troubleshoot a problem called "no network".

Incorrectly set time in the settings

This happens after updates and flashing, as well as after repairs in service centers. To fix this problem, you need to connect to wifi networks. Next, go to Settings - General - Date and time and activate the item Automatically. Reboot phone. Please note that these actions must be carried out while being connected to a wi-fi network, otherwise the cellular network will not come to life.

Cellular carrier settings and updates

Have you checked the date and time, but the "no network" message has not disappeared? Perhaps the operator does not provide its services in the region where you are located. Then you can try to activate the "on the plane" mode for a few seconds. We do the same if you are in your home region. It happens that the connection is "buggy" and you just need to restart it. You can also turn the machine off and on. If this does not help, then you need to check the operator settings. Go to Settings - Operator and check if the Automatic mode is activated.

Do not forget about the update for the system. Reconnect to Wi-Fi. Go to Settings - General - About this device. If updates are available to you, the operating system will prompt you to install them. If Wi-Fi does not work, connect to iTunes. Then update your device to the latest version of iOS.

Damage or failure of the SIM card

In the process of independently solving the problem of finding a network, you should pay attention to the SIM card. Often, it can be damaged when trimmed, it can fail if moisture gets in, or for other reasons. Pull out the SIM card using the key located in the box from under the phone, put the SIM card back. Turn on - turn off the "in the plane" mode several times.

iPhone locked by carrier

It happens that the gadget is blocked by the telecom operator under the SIM card of a certain operator. The phone simply does not support other SIM cards, writes "no network". You can contact us at service center, we will be able to unlock by imei. As a rule, such a service takes from several days to 10 days, depending on which operator the device is locked to.

Damage to the antenna responsible for receiving the signal of the cellular network

Often there are cases when the iPhone stopped catching the network due to antenna damage due to impact, moisture and oxidation, previous repairs, defective spare parts. To eliminate such a malfunction, you need to contact us at iConceptService, where qualified craftsmen will diagnose and repair the device.

Damage to the modem part and eternal network search

If the modem part is damaged by impact, moisture motherboard, then the phone will constantly search for a network and there will be no modem firmware in the settings.

Since you have stumbled upon this page, it means that most likely you are faced with the problem of no network on the iPhone 6. I hasten to please you right away, it is repaired in 9 cases out of 10. Now I will tell you what breakdown options are and what actions can be done at home for fault diagnosis.

Not iPhone networks 6

Why the iPhone 6 does not catch the network and what to do.

Reception problems cellular signal there may be stably manifested and so-called “floating” defects. It is rather difficult to work with the latter, since they may not always and everywhere appear. Sometimes there is no problem at all and not very good coverage of the mobile operator is to blame. Stable problems are easier to solve, here are some of them:

  • iPhone 6 does not catch the network, is constantly searching, or writes “No network”;
  • The phone often loses signal;
  • The network indicator is displayed, but iPhone does not receive incoming or outgoing calls.

The reasons for this behavior can be both software and hardware.

There is no network on the iPhone 6 due to the software part, what should I do?

If a iPhone 6 not catching the network and the operating system is to blame for this, then first check the correctness of the set date and time. In firmware starting from iOS 7, there is no signal reception or it is displayed incorrectly until the correct date and time are entered, after which it is advisable to reboot the phone.
You can check it by going here: "Settings" - "General" - "Date and time".

If everything is in order with the date, and the iPhone writes “search for the network”, then you can try to reset the settings.
You can do this by going to: “Settings” - “General” - at the very bottom, the item “Reset” - “Reset network settings”











We go to "Settings" Next, the item "Basic" Next, "Reset" Click "Reset network settings"

After that, the iPhone will ask for confirmation and start resetting the settings, after which it will reboot. If it helps, great! If not, then read on about hardware failures.

iPhone does not see the network - hardware problems.

There are more options for hardware failures than in the case of operating system. Usually, the iPhone 6 does not see the network or loses it due to the following problems:

  1. SIM card;
  2. Antenna;
  3. Motherboard.

First, try removing and reinserting the SIM card. If this does not help and the iPhone is still searching for a network, then try contacting your mobile operator for a replacement SIM card. Don't forget to take your passport with you.
Is the sim correct? Then let's move on. Go to menu “Settings” - “General” - “About device” and scroll down to IMEI.




It should contain the serial number of the modem, consisting of 15 digits, if it is not there, then, alas, there is nothing good here, the problem is in the motherboard. In this case, the problem is with the motherboard.
If the IMEI is in place, then there may be a problem with the antenna, in which case you need to install a new known-good antenna and look at the result.

Motherboard related problems, iPhone 6 modem replacement.

I took this problem under a separate heading, because recently there have been a lot of calls with devices in which the modem “fell off”. Basically, these devices stop catching the net after falls, less often no network after water.
The modem part of the iPhone is a group of chips. The modem has a processor, flash memory, amplifiers and many auxiliary elements. If any element fails, the iPhone 6 may begin to periodically lose the network or not find it at all. The modem chip is soldered to the motherboard using small contact balls.


Specifically, for sixes, very often 2 contacts under the modem chip break from falling. This problem is solvable, we can restore contacts and re-solder the iPhone modem.

In terms of time, diagnostics, repair and testing of malfunctions associated with network reception takes, on average, several working days. The guarantee for work is usually from 1 to 3 months, depending on the specific case.

If there is no network on the iPhone 5, 5s, 5c, 6, 6 plus, 6s, 6s Plus, 7, 7 Plus, contact a trusted service center, where a specialist will determine the source of the problem in less than 15 minutes and fix it within where - an hour.

Why the iPhone does not catch the network

The reasons why the iPhone 4 or 5 does not catch the network often lie in the breakdown of the antenna or transmitter amplifier. Of course, such a problem requires contacting a service center, whose specialist, using special tools and spare parts, will restore the normal operation of the device.

Sometimes an iPhone 4 or 5 doesn't have a network when it's locked to a specific carrier. In this case, an unlock will be required, which will solve this problem once and for all.

Also, the problem may be malfunctions of the radio unit strapping or printed circuit board tracks. This usually happens after the device falls (as a result of which some contacts break) or moisture gets inside (the elements begin to oxidize).
