If your iPhone is constantly looking for a network, do not rush to immediately carry it to a service center. In most cases, you can fix the problem yourself. Below are four ways to help you understand how to fix the problem on the spot.
First, check your Airplane Mode settings, which may allow Wi-Fi to work and always turn off cell searches. If this mode is turned off, and the smartphone does not see mobile operator try the steps below.
Check date and time settings
If your iPhone is constantly searching for a network after iOS firmware or component repair, a lost date and time setting may be the cause of network loss. To restore the search and the mobile operator icon reappears on the iPhone screen, try the following steps:
- connect iPhone to Wi-Fi, which is caught without a SIM card
- go to "Settings" menu
- sequentially select the "Basic" tabs, then - "Date and time"
- turn on the "Automatic" icon (turn it off and on again if it's already active)
- restart an iPhone that has stopped picking up cellular communication
After repeated iPhone downloads should catch the network, and the icon of your operator will appear on the screen of the mobile device. If the search mode is not restored, go to another method.
Make sure the SIM card is working
Sometimes the iPhone “does not see” the network, not because of the mobile operator, but because the SIM card has failed. A mobile device without a SIM card that works properly will “hang” indefinitely. Options for correcting this situation on the spot:
- move your SIM card to another iPhone and check if it works
- buy a new sim card for your smartphone
iPhones purchased in other countries can be "locked" to a specific mobile operator, as a result of which they do not work with Russian cellular networks. You need to unlock Apple smartphone and his reactivation. Perform this action with iTunes programs by making a copy beforehand. With this procedure, the settings are reset, established by the owner, and data loss on the phone. But in the end, you will restore the cellular search mode.
Try flashing your phone
Perhaps your iPhone is constantly looking for a network because there was a software failure. This happens when installing new applications or illiterate modem firmware. You can restore the device to its original state by resetting the parameters recently installed, or by flashing the phone again.
To reset cellular settings, go to the iPhone's "General" menu, select "Reset". The system will offer several options for action:
- reset all settings
- erase content and settings
- reset network settings
- reset home settings
- reset geo settings
First of all, try updating your iPhone through a network-related settings reset. If a constant search network continues, do full reset and return to the factory settings of the smartphone. If after that the phone “hangs” endlessly and does not catch the signal of the mobile operator, try to fix the problem by flashing software. To do this, follow the instructions for installing a new modem firmware:
- update iTunes on your computer to latest version
- create a backup
- download the latest one for your iOS phone model
- open iTunes again, click Shift key(Alt-Option) and the "Restore" button
- select the downloaded file of the new software and start the update
These are all methods that tell you how to fix a failed cellular settings on the spot. If, after a reset, your iPhone is still constantly searching for a network, take it to the wizards to diagnose the device and restore it. Most likely, the device stopped catching the network due to malfunctions of the internal electronic components. Here you will need professional diagnostics device to help determine the type of repair needed.
Repair types
Often diagnostics Apple devices, which have ceased to catch the network, reveals the oxidation of the internal elements of the smartphone as a result of moisture ingress. If you often use your phone outdoors under adverse weather conditions, such a situation is quite possible. Also, diagnostics of the device may show the need for the following measures.
Any modern smartphone is, first of all, a mobile phone, and then everything else. His most important function- receive calls and make calls. To do this, a SIM card is installed in each device with an assigned telephone number, and a special indicator indicates successful registration in the cellular network and signal strength.
iPhone does not catch the network - what to do? This problem prevents voice calls so we need to deal with it.
Trying a reboot
Smartphones iPhone 4s, 5s, 6s and many others - this is technically complex devices, consisting of several modules built on one system board. These modules work due to complex software. No software or electronic device is 100% reliable, and the same is true of the iPhone.
A failure in one module often affects other modules, causing the equipment to fail. Computer users know perfectly well what to do in the event of a partial freeze of a program or the entire PC at once - press the reset button. There is even a saying "Seven troubles - press reset." And this proverb, although modernized, contains a grain of truth - If the iPhone does not catch the network, just try restarting it.
It is possible that due to some kind of failure, the device is unable to register on the network, requiring a reboot.
As practice shows, the reboot process really relieves complex electronic devices from "glitches" and restores their performance. If your iPhone does not see mobile network, try to restart it - it should work.
Problems finding a network
Has your iPhone stopped catching the network, although until recently the indicator showed confident reception? It is possible that the smartphone for some reason cannot register with the cellular network. What to do? Let's try to help smart device. To do this, go to "Settings - Operator" and wait for the search results, then click on the name of "your" network.
Problems with search and automatic registration on the network are rare. They appear as a result of some failures on the side of the mobile operator or as a result of some errors in your smartphone. You can try to find the network manually or just restart your device- after that, an automatic search will work in it.
Another reason for failure in choosing a network can be being in international roaming. It is possible that you tried to register in some network manually, and then forgot to turn on auto mode. There are also recommendations according to which you need to reboot Cell phones for the most correct registration in your own or in the guest cellular network.
Problems with the SIM card
Does your iPhone have poor network reception and constantly lose signal? The problem may be related to incorrect work SIM card installed in the device. What can be done?
- Buy a new SIM card with a new number;
- Contact a mobile phone salon to replace the SIM card while keeping the number;
- Try testing another SIM card.
If you suspect that cellular registration failures are due to problems with your SIM card, try testing your smartphone with a different SIM card. So you can understand what it is connected with bad connection with a network.
Don't want to lose your number as a result of a broken SIM card? Contact your nearest communication salon and get a duplicate. Do not forget to take your passport with you, otherwise the duplicate will be refused.
Other ways to solve the problem
If your iPhone does not catch the network well, then this may be due to its breakdown. Self repair device is not possible, so you will have to take it to the nearest service center. Here, the smartphone will be tested and repaired, after which you can safely use cellular communications.
Problems with registration on the network (as well as any problems with electronic stuffing) often appear after dust or moisture gets into the device. Lack of normal connection to cellular networks may indicate insufficient signal strength of your operator at the current point.
And do not rely on the fact that "iPhone catches everywhere." Sensitivity for everyone mobile devices, whether it's an expensive 64 Gb iPhone 6s or an old Nokia 1110 with a b/w screen, it's about the same - you'll have to take off your rose-colored glasses and try to look for a place where you'll see a strong network signal.
The original solution to the problem with the lack of normal registration in the cellular network can be reset to factory settings. You can also try to restore via DFU mode- sometimes it helps to restore the functionality of iPhone smartphones.
Sometimes users encounter such a problem while on a trip using roaming, after, hardware repair(replacing the battery or display) of a 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 in such cases is the cause of the "breakdown" and how to fix it.
In contact with
The problem is exacerbated by the fact that employees of service centers in Russia, Ukraine, Belarus, etc. are not always able to detect real reason lack of connection to the cellular network (or deliberately hide it) and perform a number of expensive procedures - from a simple reinstallation of iOS to 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 if the SIM card is working 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)
In case of the described problem, 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 WiFi networks;
2 . Go to Settings → Main → date and time ;
3 . Toggle the checkbox " Automatically» to the 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 have ever traveled abroad with your iPhone, you may have experienced 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 technical forum Apple support there is 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 a few hours of careful reading.
System message "No network" (Searching for a network) appears when your iPhone or iPad (yes, the problem is also relevant for "apple" tablets) cannot connect to it, or connects to the operator, but cannot establish a connection to either the Internet or the cellular network. You can even see the name of the operator that serves you - but then it will disappear anyway.
This error can have several reasons. But first, you should exclude the most common and simple of them. And anyone can do it.
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 should it be done this way? Experience shows that not all mobile operators abroad provide 4G/LTE roaming. As a result, which is logical, your iPhone or iPad does not connect to networks - simply because there is nothing there for "foreigners". And 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.
We 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 iPhone (iPad)
2. Update carrier settings
For this:
- Connect to the Internet via Wi-Fi or mobile operator.
— Select Settings → Main → About this device. If your carrier has prepared a settings update, you will be prompted to update to them.
3. Remove the SIM card and insert it back
4. Reset network settings
Settings → Main → Reset → Reset network settings. Do not forget that this operation resets the 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. Ask your cell phone provider for help
Ask him if the account is active or not technical problems with a connection in your area.
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 opposite the inscription is enabled Cellular Data.
2
. If you are abroad, check if your data roaming settings are active ( Settings → cellular → Data options → data roaming).
Keep in mind that the cost mobile traffic roaming is much higher.
Like these ones simple methods in some cases, they will help to avoid going to a service center and save a decent amount, which could be billed by dishonest specialists.
There are several reasons why the iPhone does not see the network. The most common is the failure of the date and time zone. Such, at first glance, insignificant change can lead to the fact that the device will not function normally. Other causes may be much more serious, some of which cannot be corrected on their own.
Perhaps the iPhone does not catch the network due to a failure with the operator. Then you just need to restart the gadget. If such manipulation did not lead to the desired result, then you should go to the phone parameters. Perhaps this happened due to incorrect input of the time zone and time. To check you need:
- Enable WiFi.
- Go to the "Date and time" settings.
- Select the "Automatic" item, which will allow the iPhone to independently determine the zone in which the user is located.
- Reboot your device after a few minutes.
But sometimes this method may not work. Then you need to check if 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 that, the search for the operator will begin.
If this does not help, then it is worth checking the provider's parameters:
- Go to "Operator".
- Verify 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 a breakdown. To begin with, it is worth checking the status of the power amplifier in the "Modem Firmware" item. If it is missing, then the amplifier is in a faulty state. If the reason lies in the breakdown of the radio module, then it will not be possible to independently determine this fact, they will be able to confirm the guess at the service center. These elements are damaged after a fall or constant exposure to adverse external environment such as high humidity.
Another common cause is a software installation error. iOS software. In this case, you will need to reinstall the software.
Phone loses connection in the cold
iPhone gadgets, like any flagships, cannot always function normally in severe frosts. To keep it out of the cold, look out for 3G and GPS, which should be turned off as they too can interfere with the connection. When disconnecting, you need:
- Toggle Airplane Mode to OFF.
- Reboot phone.
- Check if the communication settings are correct.
If after that the iPhone loses the network, you will have to contact the service center.
Rearranging the SIM card
Alternatively, try swapping the SIM card. There are situations when contact paths move away from the SIM card and contact is lost, making authorization on base station impossible operator. In this case, there is a "disappearance of the network", all the "sticks" disappear and only a reboot helps.
To do this, use a special paper clip from the box. We insert into the hole and gently press, we leave the tray with microSim. We examine and insert the structure back, being careful. Now we restart the device, in 40% of cases this will help.
No carrier support
If the iPhone 4, 5, 6 model does not catch the network, then there is a high probability that it only supports the settings of a specific operator. Often this can be found on non-activated models coming from the USA. Such smartphones is coming binding to the operator AT & T and without a special "unlock", work on the territory of the former CIS will be impossible.
But if the activation did not bring the desired results, then you will have to reset the settings. To do this, go to the "Basic parameters" and reset the communication parameters.
If the activation took place using the SAMPrefs program, then the process will not be able to go through automatically. To reset the settings you will need:
- Open iTunes.
- The mobile must connect to the computer.
- Perform backup and restore.
- After the recovery procedure is completed, select the "recognize as a new device" item.
Problems with 3g
The signal may disappear due to the influence of 3G, which blocks access to the voice channel and the device starts to catch the signal poorly. First you need to check the settings, if they are entered incorrectly, then perhaps the problem will be fixed by resetting the parameters.
Often this method helps only for a short time. For complete fix cell phone, it will have to be taken to specialists for work on flashing the phone. It is not recommended to carry out this procedure on your own, because if a mistake is made during the process, the iPhone will turn into a “brick”.
Change of time
If the time and date are incorrectly set, then there are two ways to change this. The first - automatic installation dates that require a Wi-Fi internet connection. To do this, you need to set the item in the parameters automatic detection time zone, then reboot. The second way 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".
Airplane mode check
To resolve this issue, you will need to turn airplane mode on and off. If the SIM card is working, then this may help. It is worth paying attention to how the SIM card was cut, as in some cases the chip itself is damaged, which makes it impossible to connect to the satellite.
Update iphone or ipad
System crash causing iPhone not to see network connection, can happen for any reason: got up wrong new firmware, certain software does not work correctly, installed unlicensed programs and much more. In this case, searching for new assemblies through the settings menu can help.
If the smartphone detects available iOS versions, then it will require only the consent of the owner to start 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, therefore, when buying a phone, it is recommended to order a suitable SIM card for the connector of Apple products;
- antenna malfunction;
- damaged modem part and others.
Smartphones have a complex structure, so if the above steps did not help, then the owner will have to contact the service center. In no case is it recommended that users independently reflash a smartphone from scratch (does not take into account system updates through internal programs), as this can lead to a complete loss of performance.
Video
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. Do the same if you are in 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.
