We solve the problem of the lack of a network on the iphone. What to do if the iPhone is not connected to the operator iPhone 4 there is no network what to do

During operation, it happens that the iPhone does not catch the network. Situations when the iPhone does not see the network may be associated with device settings and external malfunctions.

The reasons for the loss of the network in the iPhone

The reasons why the iPhone 5 is poorly networked can be the following factors:

  • the presence of external problems with the card, for example, its incorrect cutting;
  • there is a problem with the antenna on the iPhone;
  • there are no funds in the account;
  • card blocking;
  • a common reason why the iPhone 5 does not see the network is incorrectly set time and date;
  • bad weather conditions;
  • blocking by the communication adapter;
  • the formation of some problems with the device itself.

If the above problems arise, it is possible to solve them on your own, without contacting a telecom operator.

Eliminating the causes of problems

If your iPhone 5s doesn't pick up the network, you can try restarting your device. In the absence of results, you should perform a number of the following actions:

1. Go to the setup operation and turn on Wi - Fi.

2. Date and time must be selected (function - "Basic parameters").

3. Activate the function - "Automatic". If it has already been activated, turn it off and on again.

4. Wait about a minute and restart the device.

Perhaps the operator is located in a remote area and is not able to provide quality services. To eliminate this situation, you should enter the operating mode and select the function - "Airplane mode", then wait 5-10 seconds and turn off the device. Upon completion of these operations, the iPhone will start searching for the network. Sometimes you need to install a system update. To do this, you need to go to the "About this device" section, where there are new system files, and then connect the Internet, while simultaneously starting the update process.

Very often, the iPhone does not see the network or there is no network in the iPhone 5, due to malfunctions after unlocking. To correct this situation, a complete reset of the settings will be required. You will need to attach a card with the choice of the option - "Reset network settings". The occurrence of network problems in the iPhone 5, as well as in the iPhone 4s, iPhone 6, may occur when activated using SAMPrefs, Redsnow systems. If the unlocking process was successful, but there is still no network in the iPhone, you need to reset the settings. Then you will need to insert a card and connect to a computer, while simultaneously connecting to iTunes. Make a backup and click on the function - "Restore" and select the section - "Recognize as a new device".

Using a third party iPhone


What to do if IOS has been flashed and in the process of replacing the card it happens that the iPhone 5, iPhone 4 and iPhone 6 does not catch the network and shows the lack of a network on the screen? A simple solution in this situation is the creation of Wi-Fi, using a third-party iPhone, connecting it to the Internet and distributing a wireless communication option.

The order of actions if the iPhone cannot see the network using another device:

If this method is unavailable, it remains to carry out the IOS firmware process, while simultaneously downloading the firmware file and connecting the smartphone to the computer where iTunes is installed. In the application, select the function - "Restore". This deletes personal data.

Sometimes the reason why the five es or the iPhone 4 does not catch the network well may be a strong contamination of the card tray. In this regard, it is desirable. carry out a high-quality cleaning of the tray from accumulated dirt and moisture. It often happens that after flashing the iPhone 3gs does not see the network or says there is no network. In such cases, a visit to the service center will be required, since, most often, this is caused by the device blocking the adapter.

In the process of blocking for cellular communication, when the phone does not support other cards, you should contact the service center, where you will be offered to unlock by the IMEY - code. Then you can use other cards. In the course of these activities, it will be possible to choose a suitable operator by visiting the main page of the resource. If the names of the operators are unfamiliar, you can use IMEY - check the network logos and order this service, with a careful study of the offers provided. If the iPhone is blocked by operators and blocked by iCloud, it will be necessary to unblock iCloud (in this case, the iPhone should not be blacklisted). After that, order the service from a suitable operator. If there is a problem with the iPhone 5 not catching the network due to hardware issues, it will most likely need to be visited service center for the repair of this equipment.

When the question arises - "why does the iPhone not catch the network?"

Here are the common causes of network and signal problems on iPhone.
If the iPhone does not catch wi-fi, it will help you.

1. Weak signal

Sometimes buildings do not transmit well the signal of the cellular network due to the peculiarities of the building or their location. If you urgently need to call, try finding the network elsewhere.

2. Problems with the SIM card

Does the iPhone see the SIM card? If not, it will help you.

3. GSM signal jammers

In some institutions, there may be so-called "jammers" - jammers that jam the signal of cell phones.

4. You are out of range of the operator

If, for example, you bought a SIM card regional operator and arrived in Moscow, then your SIM card will switch to one of the three popular operators.
If this switch does not happen and the operator icon, as well as the signal indicator, is not present, try restarting the phone.
You can independently choose an operator from the list. Go to Settings → Operator, disable the "Automatic" option, the list of operators will be loaded.
If that doesn't work, buy a local SIM card.

4. The phone was brought from abroad

An iPhone purchased in another country may be locked to a specific operator. For example, an iPhone from America will only work with AT&T.

5. Reboot required

6. Network settings need to be reset

Open Settings → General, click "Reset network settings".

7. The phone has been dropped or moisture has entered

If you dropped your iPhone and it stopped catching the network, then the GSM module is most likely damaged. A fall could have left more serious damage, such as damage to the motherboard. Moisture trapped in the phone case is also destructive. The exact cause of the malfunction can be determined by sending the iPhone for diagnosis. The Macsouls service center will do the diagnostics free of charge and in 15 minutes.

8. Software glitch

A system malfunction could cause the iPhone to poorly pick up the network. If, after diagnostics, it turns out that the reason is iOS failure, we will do a flashing. Flashing any iPhone model (iPhone 3G / 3GS, iPhone 4 / 4S, iPhone 5 / 5S / 5C) will take no more than 25 minutes.

In the world of Apple phones from Apple, not everything is as smooth as the manufacturer says. The "No network" error on iPhone is one of the most unpleasant phenomena. Moreover, she met on the iPhone 4, then was on the iPhone 5 and 5S. And the sixth version was not spared by this nuisance either.
There are three cases in which this error can occur.

1 The phone was brought to Russia unofficially and locked under a certain operator.
Many people who bought an iPhone on EBay or other foreign exchanges faced this. due to this, the price of the device comes out significantly lower. Only such a phone will not work without unlocking and will give this iPhone an "No network" error. There is only one way out in this situation - to take it to a specialist and pay for unblocking. You can't think of anything else.

2. Software failure of the smartphone.
This also happens - he's all Chinese, although there is an Apple nameplate. Restart your phone first. If he again does not find the network, then try to go into the settings and move the "Airplane mode" slider back and forth several times:


It's funny, but sometimes it works.

If you have just updated the firmware or reflashed your iPhone, after which the message "No network" appears, then very often the reason is in the incorrectly set time and date. To change it - connect your phone to with Internet access. After that - go to Settings >>> General >>> Date and Time:


There you need to find the slider automatically and set it to active mode. If it is already on, turn it off and on again. After that, restart the device.

The reason for the appearance on the iPhone of the "No network" error may be a failure in the settings of this cellular network itself. Try resetting them to factory defaults. To do this, go to Settings >>> General >>> Reset:

Click on the "Reset network settings" button. The phone will give you the following confirmation:

Click on "Reset settings", after which you need to reboot and check if the network has appeared.

If all else fails, try updating your iPhone through iTunes. If you have a backup, try rolling back to it.

3. The last possible cause is a hardware problem with the phone.
Most often - with an antenna. Or a radio module. If the "No Network" error on the iPhone appeared after you wet it or dropped it, then most likely this is what led to the problem. There is only one way out - a trip to the service center. I'll tell you right away - repairs are usually not cheap, so get ready for financial expenses.

IPhone 7 users may experience poor cellular reception. Moreover, the connection often fails at the most inopportune moment. The first step is usually to determine the frequency of signal shutdown and check the operation of the SIM card.

By the way: poor network reception is in second place in terms of the popularity of calls to service centers (after glass replacement).

You can donate to Repair iPhone 7 in any of the branches of our service center and wizards will quickly eliminate any problem in the operation of your smartphone.

Note! If the SIM card does not work in the iPhone 7, but connects to an old Nokia, such a SIM card is still considered faulty. To prevent frequent disconnection from the network, it is recommended to replace ten-year-old Beeline or MTS SIM cards with the latest samples (which can be done at any operator's office absolutely free of charge).

Diagnosing the problem why the iPhone 7 does not catch the network

  1. The phone is out of range. For example, when you go on a trip or move to another city, you find that your iPhone 7 is not picking up the network. Restart your phone - an available telecom operator will connect automatically. If this does not help, then try to go to "Settings", select "Operator" and turn off automatic operator selection. If there is no result in this case, then all that remains is to buy a SIM-card of an operator working in this city.
  2. The phone was flooded with water or dropped. The accumulation of moisture inside the phone is often the reason for the corrosion of the board. If dropped, it can also damage important components on the motherboard. Such repairs are considered quite difficult: a whole set of microcircuits, switches, amplifiers, receivers and other elements that fail both together and separately are responsible for the phone's operation. To determine the localization of the problem, you need to ring the power circuit of the modem, check all the working elements. Further, the faulty parts are soldered and new ones are installed. The best way out here is to take the device to a service center.
  3. iPhone 7 won't connect to the network due to software glitch. If a bad signal or a complete lack of network is caused by system malfunctions, then diagnostics are needed to fix such a problem. An iOS crash requires a phone flashing, which can be done in the service (in about 20 minutes).
  4. Network suppression. The signal is muffled by walls made of iron, brick or concrete, as well as in elevators and basements. Buildings are sometimes fitted with special systems to suppress the network, creating interference. In any of these situations, the problem is solved the easiest way - you just need to go outside.
  5. iPhone 7 was imported from another country. At the same time, the network is not caught due to the fact that the phone is programmed to interact with a specific telecom operator. To unlock such an iPhone, it is better to contact the appropriate services.
  6. The signal receiving antenna is defective. If you see “No network” on the screen of your iPhone, then the problem may be an antenna failure. TO motherboard the antenna is attached with a coaxial cable and a special connector - under mechanical stress, it can jump out of the socket. At the service center, the antenna will be returned to with the addition of a small amount of seal. As a result, the iPhone, which has not seen the network, starts to work like new.

The lack of network on iPhone 7 is often fixed with a simple factory reset. Go to "Settings", select "General", "Reset" and click on "Reset network settings".

Many iPhone users often experience the problem of network disconnection, which leads many to panic and haunted.

You need to reboot your smartphone using a deep reboot, for which you need to press the Home key at the same time as the Shutdown key. The phone may work better due to a complete reset of all network parameters and their update, but if this does not happen, you can try several other methods.

Causes and actions when the problem is identified

You need to carefully remove the SIM card and make sure the contacts are completely clean. They can be blown off with compressed air.

Another reason for this problem may be that many buyers of these phones, not thinking about the consequences at all, can damage the contacts of the SIM card when cutting it. This procedure must be carried out with the help of a specialist in an authorized store.

Another way to restore iPhone connectivity is to connect to Wi-Fi and set the correct date and time, which can be quickly done in the settings menu. You can try turning the airplane mode on and off a couple of times, which can often help you out.

Troubleshooting a factory unlock problem

The most common cause of the error is unlocking using the Ultrasnow program or updating the firmware to the iPad version. This is not at all related to the hardware, since the “no network” error means that the smartphone has accepted the SIM card, but there are obstacles to getting a connection in the program structure.

One of the most popular and surefire solutions to the problem is to reset network settings through general settings. You can also try to delete the information, which can lead to damage to the existing program code.

Error when activating / deactivating iPhone 4s via Ultrasnow or SAMPRefs applications

To fix this problem, you will need to insert your sim card and connect it to your computer with iTunes... Next, when iTunes detects the phone, you need to make a back-up and click “Restore”. After completing the recovery process, you will have two options available:

  • Recovery from back-up.
  • Use iPhone like a new phone.

If none of the methods helps

The main thing is that if none of the above procedures helped you, you will have to contact the service center, since the loss of communication is a rather serious and complex problem that must be presented to real specialists for solution.

After all, quite often connection problems arise due to a breakdown of the antenna. In this case, for models 4, 4s and 5s, you need to contact the official center, which can quickly and efficiently replace this very antenna.

It is not worth giving your smartphone to third-party organizations, since the IPhone does not catch the network due to the incorrect operation of the internal amplifier. This problem did not often arise for 4s, however, in the first batch of the five it was almost at every step, which partly led to a decrease in the popularity of models.

Many Internet services offer services for restoring the network of iPhone 4s and later versions through the IMEI number. If you unlock your smartphone in this way, you can use SIM cards of any operators on it.

If the cellular operator is blocked in the iPhone 4s, 5s, 6, 6s, then you have to unlock iCloud, which can also be ordered on these resources, and only then purchase the unlock service from the cellular operator.

Also, if you are interested in games on iOS or Android, then you can search for them at QGamer.ru.

There are situations when the iPhone stops seeing the cellular network. In some cases, you can determine the cause and fix the problem yourself, without the help of specialists.

Network problems

It happens that after reinstallation, reset or iOS updates the device starts to catch the network badly or stops doing it altogether. A similar problem appears not only due to breakdowns in the system part, but also due to malfunctions in the physical component of the phone. Network problems will be reported by an inscription in the upper left corner of the notification panel - "No network" or No Service.

In the upper right corner of the screen, you can see a message stating that there is no network

If the problem lies in the system part of the iPhone, then it will most likely be possible to fix it yourself, but if the SIM card itself or one of the parts responsible for communication is damaged, then you will have to contact special services to fix Apple equipment.

How to fix the problem

First of all, you need to make sure that where you are, other devices with SIM cards of the same cellular operator are picking up the connection. You may just be out of coverage. It is also worth getting out of places where the signal can be drowned out by a dense ceiling, walls or special devices.

If there is a signal on other devices, then it is worth following the instructions below, which may return the network to you.

Time change

Incorrect time and date parameters can cause the signal to disappear. Errors can occur even if the minutes do not match, so it is recommended to set auto mode time reconciliation:

Checking the airplane mode

First, make sure airplane mode is off. Its status can be seen in the Quick Access Toolbar. Secondly, if it was turned off, turn it on for 15 seconds, and then turn it off again. These actions will reboot the SIM card and, possibly, return the network to it.


Turning airplane mode on and off

Data reset and refresh

  1. While in the device settings, select the "General" section, and in it the "Reset" subsection. Open the "Reset" section
  2. Reset your network settings. Resetting network settings
  3. Return to the basic settings and click on the "About this device" button. Automatic diagnostics for cellular updates will be carried out. If they are found, you will be prompted to install them, confirm the action and wait for the end of the process. Go to the section "About this device"
  4. Go back to device settings and select " cellular", And in it the sub-item" Cellular data ".
    We open the section "Cellular communication"
  5. Please fill in all empty fields. The data for them can be taken on the official website of your mobile operator. Entering cellular data

Physical check

If the above steps did not help, then you need to check the SIM card. Pull it out and check if it works on another iPhone. If the network is not found there, then the SIM card will have to be replaced. This can be done at the nearest service of your cellular operator.


Checking if the SIM card is working

If the SIM card works in another device, then there are two options: either some part of the phone is damaged and it needs to be taken to the service, or errors appeared in the firmware that prevent the SIM card from working, and you will have to perform a recovery.

How to restore a device

If you have an iCloud or iTunes backup, you can reset your device without losing your data. Otherwise, the whole personal information and installed applications will be irretrievably lost, so make sure you have a backup beforehand. After that, connect to a Wi-Fi network, go to the basic settings of the device, then to the "Reset" subsection and select the "Reset content and settings" function. Go through the reset procedure, after it ends it will start initial setup device, at one of the steps of which you can specify from which backup you want to restore your device.

How to avoid similar problems in the future

In order not to lose the network in the future, do not change the settings of the device and SIM card, if you are not sure exactly how to do it correctly. Do not often insert and remove the SIM card, this can harm it. Also don't forget to update backup, stored in iTunes or iCloud, so that in case of damage to the system part of the device, you can recover information without loss.

If iPhone doesn't pick up the network, check to see if you are within range. After that, change the date and time settings, use the Airplane mode function and reset the network settings. If this does not help, reset the settings and content of the device, and then take it to a service center.

It is not a pleasant situation to be "on hand" with an iPhone that does not catch the net on a trip or on a business trip. The boss will be annoyed that his employee is unavailable and did not submit a timely report, relatives will be worn out with anxiety, potential clients will be off the hook. Even calling for help or a taxi should something happen to the car, it will be impossible. It should be admitted that modern people are heavily dependent on the GSM signal.

Fortunately, in most situations, you cannot solve the problem of a weak network on your own and rather quickly. In this article, we will tell you about the common reasons why the "apple" gadget does not catch the network well, and how to fix the situation.

First what you need to check on an iPhone that does not pick up a GSM signal - date / time settings. If the settings are incorrect, you should set the correct manually... This is done like this:

Step 1... Follow the path " Settings» — « The main» — « date and time».

Step 2... Find out the exact time in your time zone. To do this, you can use, for example, the Yandex. Time" .

Step 3... Scrolling the reels, set the correct date, hour and minute.

Step 4... Restart your iPhone and check the network.

If you have Wi-Fi access, you can avoid manual setting time. In the subsection "Date and Time" there is a slider "Automatic". After activating it, the iPhone independently determines the time in the set time zone - but only if the gadget is connected to the Internet.

Your humble servant prefers not to use automatic tuning time, because his iPhone "counts" one hour more.

Problems with the settings of the cellular operator

If the time is set correctly, but the iPhone still does not catch the network, you can suspect that the settings of the cellular operator are out of order. A set of such measures will help to solve this problem (each subsequent step must be performed only if the previous one did not work):

Step 1... Turn airplane mode on and off. The corresponding slider is located at the very beginning of the " Settings».

Step 2... V " Settings"Go to the section" Operator"And deactivate the toggle switch" Automatically».

Step 3... Check if the cellular data settings are correct (APN, username, password). Follow the path " Settings» — « cellular» — « Cellular network data transmission". In the block " Cellular data»And the necessary details are present.

You can find the correct parameters for the top 3 operators in our article on. If there is a discrepancy, change the cellular data settings on the "apple" gadget manually. Remember to restart your device after changing the settings.

Weak GSM signal

If the reason for the weak signal is that the user's place of residence is not within the GSM coverage area, you cannot fix the problem yourself. You will have to buy a SIM card for temporary use. Although in fact the territory where utterly no GSM signal, you still need to search.

There are also areas where the signal is very poor in large cities. As a rule, iPhones are not caught in the subway, basements, elevators. The network can disappear inside the building due to the fact that the concrete walls of the room jam the GSM signal. In some buildings, jammers are deliberately used to prevent employees from over-engaging in Internet surfing. The "jammers" look like this:

Previously, "jammers" were willingly placed in educational institutions. Now the use of such devices has been reduced to a minimum - the modern educational process presupposes an active student's use of the mobile Internet.

If the GSM signal is weak in the user's home, this is a reason to make a claim to the communication provider. The iPhone owner needs to call hotline and complain about the lack of a network. The application will be forwarded to the technical department, whose employees will make every effort to solve the problem.

SIM card damaged

Mechanical damage to the SIM card or its incorrect cutting can not become the reasons why there is no network on the iPhone. If the card is defective, the SIM gadget will not recognize it at all. This is a completely different problem possible solutions which we suggested in the article "".

However, a user suffering from a lack of network on a smartphone should still have a visual inspection of the SIM card. If there is dirt on the contacts, you need to carefully remove it. Even the fact that the user has removed the SIM card and installed it back into the slot can help return the normal GSM signal.

If the iPhone owner has suspicions that the gadget does not catch the network well because of the SIM card, he should contact the service office with a passport and replace the SIM. This procedure is free and takes only a couple of minutes.

IOS crash

The ineffectiveness of the above measures tells the user that the problem may lie in software... For correct work gadget required Latest updates systems. To check if there is available updates, the user needs to follow the path " Settings» — « The main» — « Software Update».

There was a breakdown of the gadget

If there is a physical breakdown of the iPhone, a visit to the masters cannot be avoided. The failure of the gadget to catch the network, as a rule, is caused by a malfunction of the antenna module. Antenna breakage is the result of falling or flooding the gadget. The cost of repairs in this case will depend on iPhone models... We will collect approximate prices in the table:

IPhone does not catch the network after unlock: what to do?

Network problems can appear after the user has unlocked the Sim-Lock device using one of the following programs: redsnOw, ultrasnOw, SAM Tool, SAMPrefs. The following measures will help to resolve the problem:

Step 1... Reset network settings. To do this, you need to follow the path " Settings» — « The main» — « Reset", Click on the item" Reset network settings»And enter the password.

This measure will not result in the deletion of personal data.

Step 2... Restore iPhone via iTunes and. The probability that this measure will help is 90%. Remember that restoring will clear the device's memory. Back up your data before proceeding with the recovery procedure.

If the gadget is locked under AT&T, it will not work with Russian SIM cards, no matter how hard the user makes. The unfortunate owner of such a smartphone is better off seeking an official unlock.

Conclusion

In the absence of a network on the iPhone, you should not rush to the masters for repairs. Specialists of service centers are interested in finding a malfunction in the gadget - and they, most likely, will find it, "blowing up from an elephant fly." Before handing over the phone for repair, the user should take a number of simple measures - check the time, network settings, restart the gadget, update iOS. The chances that one of these measures will work is very high.

The constant search for the iphone 4s network is a problem familiar to many owners of smartphones of this brand. Sometimes, to eliminate it, simple manipulations are enough, which will not take much time. The simplest solution is to simply reboot the device to fix the system crash.

Checking and setting network parameters

If even after restarting the iphone 4s it writes a network search, you need to "dig" in the settings. Very often, the problem occurs when the time parameters are incorrectly set and the time zone is incorrectly selected.

To configure the parameters, you must connect the device to Wi-Fi networks... Then follow the instructions.

  1. Go to the settings menu and go to the "Basic parameters" section.
  2. Select "Date and Time". In this section there is an item "Automatic" - if the function is inactive, activate it. If it is on, turn it off, wait a few seconds and turn it on again.
  3. Reboot your device.

Most likely, the operator simply does not provide services in this area or the signal is not stable. In this case, you can activate the "Air" mode for a few minutes. After turning it off, automatic search available networks.

Sometimes the iPhone 4s does not catch the network well, because it is not installed automatic detection settings. You can enable it as follows:

  • go to the "Parameters" menu and select the "Operator" item;
  • activate automatic detection of settings.

Software update required

3g missing on iphone 4s - probably just not installed important updates... You can check information about updates by going to the "About device" menu item. If there are system files available, you need to connect to Wi-Fi and start installing them.

If not wireless network Internet. You can install updates by connecting your smartphone to a computer running iTunes.

  2. Turn off the device, remove and reinsert the SIM card.
  3. Go to the "Basic settings" menu and select "Reset network settings", confirm the action.

If these actions were not enough for complete elimination problems, you need to connect to a PC via iTunes:

  • connect your phone to your computer and open the program;
  • make a backup;
  • click on "Recovery Point";
  • after automatic reset, two options will appear further action, you need to select "recognize as new device".

Upon completion of manipulations, the device will automatically search for the network.

Other options

The reason for the constant search for the network on the iPhone 4 may be the wrong cut of the SIM card. If the chip is noticeably damaged, you need to contact the operator and order a reissue of the card in the required format. Or the card may be blocked due to violation of the agreement with the operator - in this case, an appeal to the service center is required.

Many iPhone users often the problem of network disconnection arises, which leads many to panic and haunts.
