We solve the problem of lack of network on iPhone. How to avoid similar problems in the future
There are several reasons why the iPhone does not see the network. The most common is date and time zone failure. Such a seemingly insignificant change can lead to the device not functioning normally. Other reasons may be much more serious, some of which cannot be corrected on your own.
Perhaps the iPhone does not connect to the network due to a failure with the operator. Then you just need to restart the gadget. If such manipulation does not lead to the desired result, then you should go to the phone settings. This may have happened due to incorrect input of the time zone and time. To check you need:
- Enable Wi-Fi.
- Go to the “Date and Time” settings item.
- Select “Automatic”, which will allow the iPhone to independently determine the belt in which the user is wearing.
- After a few minutes, reboot the device.
But sometimes this method may not work. Then you need to check whether the operator’s services are provided in this region. To do this, you need to turn on “Airplane mode”, and after a few seconds turn it off. After this, the search for an operator will begin.
If this does not help, then you should check the provider settings:
- Go to the “Operator” item.
- Check that the selected operator settings are correct.
If after the manipulations the situation has not changed, then the iPhone does not catch the network precisely because of the breakdown. First, you should check the status of the power amplifier in the “Modem firmware” item. If it is missing, then the amplifier is in out of order. If the reason lies in the failure of the radio module, then you will not be able to determine this fact yourself; they will be able to confirm your guess at the service center. These elements are damaged after falling or constant exposure to an unfavorable external environment, for example, high humidity.
Another common reason is an error during software installation. iOS software. In this case, you will need to reinstall the software.
The phone loses connection in the cold
iPhone gadgets, like any flagships, cannot always function normally in severe frosts. To keep it cool, pay attention to 3G and GPS, which should be turned off as they too can interfere with the connection. When disconnecting you need:
- Switch “Airplane mode” to OFF.
- Reboot your phone.
- Check that the communication settings are correct.
If after this the iPhone loses the network, you will have to contact a service center.
Rearranging the SIM card
Alternatively, try rearranging the SIM card. There are situations when the contact tracks move away from the SIM card and contact is lost, making authorization on base station operator is impossible. In this case, the “network disappears”, all the “sticks” disappear and only a reboot helps.
To do this, we will use a special paper clip from the box. We insert it into the hole and press lightly, and we take out the tray with the microSim. We inspect and insert the structure back, being careful. Now we restart the device, in 40% of cases this will help.
No support for the required operator
If iPhone 4, 5, 6 models do not catch the network, then there is a high probability that it only supports settings specific operator. This can often be found on non-activated models coming from the USA. Such smartphones are coming binding to the AT&T operator and without a special “unlock”, work in the territory of the former CIS will be impossible.
But if the activation does not bring the required results, you will have to reset the settings. To do this, you need to go to “Basic Settings” and reset the communication parameters.
If activation took place using the SAMPrefs program, the process will not be able to proceed automatically. To reset settings you will need:
- Open iTunes.
- The mobile must connect to the computer.
- Perform backup and recovery.
- After completing the recovery procedure, select the “recognize as a new device” option.
Problems with 3g
The signal may disappear due to the influence of 3G, which blocks access to the voice communication channel and the device begins to poorly receive the signal. First you will need to check the settings; if they are entered incorrectly, then perhaps the problem will be resolved by resetting the settings.
Often this method helps only for a short time. To completely fix your cell phone, you will have to take it to specialists to carry out work on flashing the phone. It is not recommended to carry out this procedure yourself, since if a mistake is made during the process, the iPhone will turn into a “brick.”
Time change
If the time and date are set incorrectly, you can change this in two ways. First - automatic installation dates that will require an Internet connection via Wi-Fi. To do this, you need to set the item in the parameters automatic detection time zone, then reboot. The second method is manually, for which you need to go to the appropriate menu item and enter data based on various Internet services, for example, Yandex. Time".
Checking airplane mode
To resolve this issue, you will need to turn airplane mode on and off. If the SIM card is working, this may help. It is worth paying attention to how the SIM card was cut, as in some cases the chip itself is damaged, making connection with the satellite impossible.
Updating iPhone or iPad
System crash causing iPhone to not see network connection, can happen for any reason: stood up incorrectly new firmware, certain software does not work correctly, unlicensed programs are installed, and much more. In this case, searching for new assemblies through the settings menu can help.
If the smartphone detects available versions iOS, then it will only require the owner’s consent to begin the operation. If this does not help, then you need to consider other options.
Conclusion
There are other sources of the problem:
- the reason is in the SIM card, it may be incorrectly cut or damaged, so when buying a phone it is recommended to order a suitable SIM card for the connector of Apple products;
- antenna malfunction;
- The modem part and others are damaged.
Smartphones have a complex structure, so if the steps described above do not help, the owner will have to contact a service center. In no case is it recommended that users independently reflash their smartphone from scratch (updating the system via internal programs), as this can lead to complete loss of performance.
Video
Sometimes users encounter this problem while on a trip, using roaming, after a hardware repair (battery or display replacement) of the smartphone or a long period of inactivity (without recharging) - the operator logo disappears on the iPhone and there is no connection to the cellular network. Let's try to figure out what causes the “breakdown” in such cases and how to fix it.
In contact with
The problem is made worse by the fact that employees service centers in Russia, Ukraine, Belarus, etc. are not always able to identify the real reason for the lack of connection to the cellular network (or deliberately hide it) and carry out a number of expensive procedures - ranging from simple iOS reinstallation and ending with hardware repairs using a soldering iron and other “jewelry” tools.
Check if the SIM card is working?
Unfortunately, SIM cards also fail. Therefore, first of all, check whether the SIM card works in your iPhone. This can be done, for example, by installing a SIM card in another smartphone.
What to do if instead of the operator on the iPhone it says “no network” or the smartphone does not see the SIM card after repair (flashing)
If the problem described above occurs, first of all you need to look at set time- if the smartphone does not display correctly current time and date, then you need to perform the following simple algorithm of actions:
1 . Connect your device to active Wi-Fi networks;
2 . Go to Settings → Basic → date and time ;
3 . Toggle the " Automatically" V active position(if set by default - turn it off and on);
4 . Restart your iPhone.
No network, search or what to do when the iPhone does not see the operator’s SIM card while roaming abroad
If you've ever traveled abroad with your iPhone, you might have encountered this problem. You turned off your smartphone during the flight, and when you turned it on, your device does not connect to the cellular network, but displays the message “No network.” What to do?
On the forum technical support Apple has a corresponding discussion thread with a million pages to read. But even if you honestly start reading everything to figure it out, you won’t get an answer to your question even after several hours of careful reading.
System message “No network” (Search for network) appears when your iPhone or iPad (yes, the problem is also relevant for Apple tablets) cannot connect to it, or connects to an operator, but cannot establish a connection to either the Internet or the cellular network. You may even see the name of the operator who serves you - but then it will disappear anyway.
This error can have several reasons. But first you should exclude the most common and simplest of them. And anyone can do this.
Switch from LTE (4G) to 3G
1
. Open Settings your iPhone or iPad.
2
. Select cellular
→ Voice and Data. 
3
. Click on the inscription Voice and Data and change LTE to 3G or 2G.
Why do you need to do this? Experience shows that not all mobile operators abroad provide roaming in fourth generation networks (4G / LTE). As a result, and logically, your iPhone or iPad does not connect to networks - simply because there is nothing there for “foreigners”. AND the simplest way to solve this problem - look for networks of the previous, third generation (3G), because it is difficult to imagine a more or less developed country where they do not exist.
Let us repeat - this situation has nothing to do with the 4G coverage of foreign operators. They can provide fourth generation networks to local subscribers, but not to visitors.
Try it - it really helps :).
Did not help?
Well, let's look at the options for solving the problem from among those that Apple offers us.
1. Turn off and on your iPhone (iPad)
2. Update your carrier settings
For this:
— Connect to the Internet via Wi-Fi or mobile operator.
— Select Settings → Basic → About this device. If your operator has prepared a settings update, you will be prompted to update to them.
3. Take out the SIM card and insert it back
4. Reset network settings
Settings → Basic → Reset → Reset network settings. Do not forget that this operation resets passwords for Wi-Fi networks, cellular network settings and preset VPN/APN settings.
5. Update iOS on iPhone and iPad to the latest version
6. Contact your mobile operator for help
Check with him whether the account is active or not technical problems with connections in your region.
7. Reset your iPhone or iPad to factory settings
What to do if the Internet does not work on iPhone while roaming
1. Go to Settings → cellular and see if the slider next to the inscription is enabled Cellular data.
2
. If you are abroad, check that your data roaming settings are active ( Settings → cellular → Data Options → data roaming).
Please note that the cost mobile traffic in roaming is much higher.
Like these ones simple methods in some cases, they will help you avoid a trip to the service center and save a decent amount, which could have been billed by unscrupulous specialists.

Video instruction
Quite often, iPhone owners, after changing iOS, repairing the phone, or a long period of inactivity, are faced with the problem of the network disappearing on the device. Why can't my iPhone connect to the network? We will talk about this further.
Incorrect date and time settings
Most often, the cause of the malfunction is an incorrectly set time, as well as the time zone. Therefore, if the iPhone does not catch the network, first of all you should look for a discrepancy in set date and time. If the phone really shows the wrong date, for the network to appear, it will be enough to carry out the following simple steps:
- You need to connect your smartphone to active network Wi-Fi.
- Enter the phone settings, open the “Basic” section and go to the “Date and time” item.
- Set the line “Automatic” to the active position (if the default state is set, you just need to turn it off and then turn it 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 ones will be discussed below.
If the "No network" error appears when correct settings date and time you need to do the following:
- First of all, you need to turn on, and after a few moments turn off the Airplane mode again.
- If this does not help, you can simply restart your smartphone.
- It is also recommended to remove the SIM card to make sure it is branded and original. In addition, you should look to see if there is any mechanical damage on it.
- After this, 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 do not lead to changes, you need to check the settings of your mobile operator, not forgetting about updates. You need to establish a Wi-Fi connection, then go to the main settings of your mobile device, open the “About this device” line. If the smartphone needs updates, the OS will automatically prompt you to install them. If Wi-Fi does not work on the phone, the iPhone needs to 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, iPhone owners encounter this problem after unlocking it using a program called Ultrasn0w or a firmware update. Also, a similar problem may appear as a result of restoring, updating, activating or deactivating the smartphone using Redsn0w, SAM tool, or after jailbreaking.
You can try to fix the problem after factory unlocking using your own IMEI number. In general, such a problem is practically not dangerous when compared with notifications about a problematic or unsupported SIM card.
Provided that when a notification appears about the absence of a network, we can say with confidence that the phone accepts a SIM card, but it does not see either the ordinary network or the Euronetwork.
The simplest and quick way, which very often helps to fix the problem is resetting the network settings. The subscriber should place 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 backing up and deleting all data, but such actions may 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 solution to the problem provides positive result in 90% of cases:
- You need to place the non-AT/T SIM card inside the iPhone and then connect the smartphone to iTunes program using a USB cable.
- After the program identifies the phone, you need to perform a backup, and then click “Restore”.
- First, it is better to try to restore the phone without using the Shift/Option buttons. You can also restore the gadget in DFU mode.
- You need to wait until the recovery process is completed, 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 offer to complete the activation. In this case, you need to use a non-AT/T SIM card and wait for the required signal.
When nothing helps, you need to continue searching for solutions and repeat all steps from the first to the fourth.
Other reasons
Often, customers who tried to cut a SIM card for a new iPhone become hostage to an error due to which the smartphone is not able to detect the card. To solve this error, you need to order a SIM card from your personal provider.
It happens that the connected provider does not provide services in that area - as a result, the Apple smartphone displays 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 “No network” problem occurs due to a faulty antenna. In such a condition, you should seek advice from professionals and preferably Apple store, where specialists will help you set up an ordinary network, as well as a Euronetwork.
Finding yourself “in your hands” with an iPhone that does not catch the network on any trip or business trip is not a pleasant situation. The boss will be annoyed that his employee is unavailable and did not submit a timely report, relatives will be worried, potential clients get off the hook. It will be impossible to even call help or a taxi if something happens to the car. It must be admitted that modern man is heavily dependent on the GSM signal.
Fortunately, in most situations you can solve the problem of a weak network on your iPhone yourself and quite quickly. In this article we will talk about common reasons why an Apple gadget has poor network reception and ways to correct the situation.
First, what you need to check on an iPhone that does not receive a GSM signal - date/time settings. If the settings are incorrect, you should set the correct ones manually. This is done like this:
Step 1. Follow the path " Settings» — « Basic» — « date and time».
Step 2. find out exact time in your time zone. To do this, you can use, for example, the Yandex. Time" .
Step 3. While spinning the reels, set the correct date, hour and minute.
Step 4. Restart your iPhone and check the network.
If you have access to Wi-Fi, you can avoid manual settings time. In the “Date and Time” subsection there is an “Automatic” slider. 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” an hour too late.
Problems with mobile operator settings
If the time is set correctly, but the iPhone still does not receive the network, you can suspect that the settings of the cellular operator have gone wrong. A set of such measures will help solve this problem (each subsequent step should be performed only if the previous one did not produce results):
Step 1. Turn airplane mode on and off. The corresponding slider is located at the very beginning of the menu “ Settings».
Step 2. IN " Settings"go to the section " Operator" and deactivate the toggle switch " Automatically».
Step 3. Check if the cellular data settings (APN, username, password) are entered correctly. Follow the path " Settings» — « cellular» — « Cellular data network" In the block " Cellular data» and the necessary details are present.
You will find the correct settings for the 3 leading operators in our article on how to set up the Internet on an iPhone. If there is a discrepancy, change the cellular data settings on your Apple gadget manually. After changing the settings, be sure to restart your device.
Weak GSM signal
If the reason weak signal The problem is that the user's location 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 absolutely There is no GSM signal, you need to look again.
There are areas where the signal is very poor in large cities. As a rule, iPhones are not detected in the subway, basements, or elevators. The network may disappear inside the building due to the fact that the concrete walls of the room jam the GSM signal. Some buildings deliberately use “jammer” devices to prevent employees from excessive Internet surfing. The jammers look something like this:
Previously, “jammers” were willingly placed in educational institutions. Now the use of such devices has been reduced to a minimum - modern educational process involves the student’s active access to the mobile Internet.
If the GSM signal is weak in the user's home, this is a reason to file a claim with the communication provider. The owner of the iPhone needs to call the number hotline and complain about the lack of network. The application will be transferred to the technical department, whose employees will make every effort to resolve the problem.
SIM card is 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 faulty, the SIM gadget will not recognize it at all. This is a completely different problem possible solutions which we proposed in the article “Why the iPhone doesn’t see the SIM card.”
However, a user suffering from a lack of network on a smartphone should still check visual inspection SIM cards. If there is dirt on the contacts, you need to carefully remove it. Even the fact that the user removed the SIM card and installed it back in the slot can help restore a normal GSM signal.
If iPhone owner there are suspicions that the gadget has poor network reception due to the SIM card, he should contact the service office with a passport and SIM replacement. This procedure is free and only takes a couple of minutes.
iOS crash
The failure of the above measures tells the user that the problem may be software. For correct operation The gadget requires the latest system updates. To check if there is available updates, the user needs to follow the path " Settings» — « Basic» — « Software Update».
The gadget has broken down
In the presence of physical breakdown An iPhone visit to the masters cannot be avoided. As a rule, a gadget’s failure to catch the network is caused by a malfunction of the antenna module. A broken antenna is the result of a fall or flooding of the gadget. Repair cost in in this case will depend on iPhone models. Approximate prices Let's put it in a table:

Step 1. Reset your network settings. To do this you need to follow the path “ Settings» — « Basic» — « Reset", click on the item " Reset network settings" and enter the password.
This measure will not lead to the deletion of personal data.
Step 2. Restore your iPhone via iTunes and set it up like new. The likelihood that this measure will help is 90%. Remember that restoring clears the device's memory. Before you begin the recovery procedure, do backup copy data.
If the gadget is locked to AT&T, it will not work with Russian SIM cards, no matter what efforts the user makes. The unfortunate owner of such a smartphone is better off seeking an official unlock.
Conclusion
If there is no network on your iPhone, there is no need to rush to the experts for repairs. Service center specialists are interested in finding a fault in the gadget - and they will most likely find it, “making a mountain out of a mountain.” Before sending the phone in for repair, the user should take a number of simple measures - check the time, network settings, reboot the gadget, update iOS. The chance that one of these measures will produce results is very high.
