“No network” (search) on iPhone in iOS 12.1.2

Working ways to fix the main problem of iOS 12.

iOS 12.1.2 brought with it a new unpleasant problem - some users' iPhones suddenly stopped connecting to the network. The problem is not truly widespread, but, nevertheless, there are enough complaints from users. How to get rid of the problem with no network on iPhone in iOS 12.1.2? We talked about two ways to solve the problem in this instruction.

Why does it say “No network” on iPhone?

After updating iOS or replacing a SIM card, there are situations when the “no network” message is displayed on the iPhone. Because of this, the capabilities of the mobile device are immediately reduced, and the phone turns into just an entertainment item.

Quite often, in this case, users take the phone to a service center, where, in most cases, the connection is returned to them for a fee. Although, most often, you can solve the problem on your own.

Weak signal

It often happens that the iPhone does not see the network due to its weak signal. This mainly happens in remote settlements where there is poor coverage, or in buildings with thick walls.

This problem can occur when you are in roaming. The solution may be to switch from 4G to 3G mode. This can be done in the “Settings” – “Cellular” – “Voice and Data” menu. If this does not help correct the situation, then you should proceed as follows:

Turn off and turn on the iPhone again;
Take out and insert the SIM card;
Reset network settings “Settings” – “General” – “Reset”;
Updated to the latest software version;
Reset the mobile device to factory settings;
Update the operator settings in the menu “Settings” - “General” - “About this device” when Wi-Fi is on.

Another reason why the iPhone does not find the network is that the operator does not provide services in this region. Sometimes it happens that a person enters an area where there is no connection, but when leaving it the signal does not appear. You can fix this by turning off and on your mobile device.

How to avoid network problems in the future

In order to protect yourself from such problems in the future, you should take care of the device: do not drop it to avoid mechanical damage to the receivers and transmitters, keep it away from moisture. You should also refrain from buying cheaper Chinese copies, since in such devices problems with finding an operator’s network are much more common. It is most advisable to buy original iPhones, a wide range of which is presented among Apple products in our online store.

Incorrect time settings

The secret here lies in the operating system itself. If the time zone and time/date do not match the current indicators, then the iPhone does not connect to the network. It is very easy to fix this problem; just connect your smartphone to the Internet and perform simple manipulations.

After connecting your mobile phone to the Internet, go to Settings, and then to the General section;

Open the Date and Time section;

Next you need to activate the Automatic option;
If the “Default” switch is in the active position, then you must first turn off this mode and then turn it on again;
Reboot the mobile device.

This method is very simple and yet effective. But first you need to connect to the Internet so that the iPhone is registered on the Apple server. If this condition is not met, the cellular signal will not appear.

Problems with the SIM card

It is worth paying attention to the SIM card. Problems with the network may occur if the SIM card was cut incorrectly and the microcircuit was damaged. Often, such a nuisance occurs among those users who are trying to save money and cut the SIM card to a smaller size at home, using improvised means.

In addition, the SIM card can be damaged if moisture gets into the connector, as well as for a number of other reasons. First you need to check the functionality of the SIM card. To do this, pull it out with a special key, which is included in the delivery set, and replace it with another one. If everything works, then you need to change the SIM card.

In some cases, turning off and on the smartphone helps. You can also try turning airplane mode on and off several times.

iOS crash

Do not forget about updating the operating system, as everything may not work correctly on the old version. To check available updates, go to Settings - General - About this device. If there are updates available, the operating system will automatically prompt you to install them. If you don’t have a Wi-Fi connection, you can connect via a cord to your computer and open iTunes there. Through it, the device is already updated to the latest available version of iOS.

Problems with operator settings

If you checked the date and time, tried to turn off and turn on your smartphone, but the “no network” entry did not disappear, then the reason lies elsewhere. It may well be that the operator simply does not provide services in the region where you are currently located.

You can try turning on airplane mode for a few seconds and then turning it off. The same can be done in your home region if the network does not catch. It happens that the connection is simply glitchy and you just need to restart your smartphone. Alternatively, turn off and then turn on your smartphone.

If suddenly this does not help resolve the problem, then you need to check the operator settings. Go to Settings - Operator and then check whether the Automatic mode is activated.

Smartphone hardware malfunction

There are often cases when the iPhone stops receiving the network due to hardware failures. The cause may be an antenna damaged due to an impact, as well as moisture that has gotten inside the case and led to oxidation of parts. The reason may also be poor-quality repairs using non-original components. To eliminate the malfunction, it is recommended to contact a company service center, where experienced technicians will carry out diagnostics and be able to repair the mobile phone in a short time.

The modem part on the motherboard may also be damaged by impact or moisture. In this case, the mobile device will also constantly search for the network, and it will be impossible to see the modem firmware in the settings. To make sure that the modem is not damaged, you should go to Settings - General - About this device - Modem firmware. If the field here is empty, then the modem is broken and only qualified technicians can help.

Replacing a modem is a painstaking and complex job that allows you to restore the modem part and bring the mobile device back to life.

Weather

The iPhone may not see the network even in bad weather conditions. It could be snowfall or frost. The cause of this problem may also be incorrect operation of a nearby mobile communication tower.

If before this the smartphone worked flawlessly, then you should wait out the bad weather and then see if the network appears. You can also turn off and turn on your smartphone after a couple of seconds.

Signs of damage to the modem or antenna

There are frequent cases when the iPhone stopped seeing the network due to damage to the antenna or modem part. This can happen due to a shock to the smartphone, moisture entering it and subsequent oxidation of the board. This may also be due to poor quality repairs or non-original cheap spare parts. Such breakdowns occur in the iPhone 4, 5, 6, 7 and 8 series, as well as in the iPhone X.

To check if there really is a problem with the modem, you need to:

go to “Settings” and go to the “General” submenu;
click the “About this device” menu;
find the “Modem firmware” field.

If it is empty, then the modem really has damage, which can only be repaired at a service center. This is quite a complex and painstaking work and it is impossible to carry it out independently, without the help of a qualified craftsman.

A malfunction of the antenna can be judged by the appearance of the phone: if the gadget has been dropped or damaged, it is quite possible that the antenna has failed. In addition, inoperative Bluetooth or Wi-Fi can also indicate damage to the antenna. Such a breakdown should also only be repaired by an authorized service center.

iPhone says “No network” - what to do

If the iPhone was working flawlessly before, and suddenly the network disappeared, then this may be due to various factors. But you should not be upset, if the device did not get wet or fall from a height before, then, most likely, the situation can be corrected on your own. You can do the following:

Turn off and then turn on the mobile phone after a minute, although rebooting the device will suffice;
Check Date/Time/Time Zone;
Activate and then turn off airplane mode;
Pull out the SIM card and reinsert it. If you suspect that the SIM card is damaged, then you should insert another SIM card and see if the network appears;
Wait a while, there may well be a breakdown on the mobile tower.

If no methods help and the treasured network icon does not appear, you should contact the service center. The cause may be a hardware failure, in which case you will not be able to fix the problem yourself.

If you have problems with your iPhone, you should only contact the company’s service center. Only in this case can you be sure that the phone will be repaired and not completely broken.

Ask a Question

Question to the expert

After updating the iPhone, it stopped seeing the network. What to do?

In this case, you need to contact a service center, preferably a branded one. It is possible that specialists will be able to solve the problem.

While roaming, the iPhone does not show the network, I cannot make calls or use the mobile Internet. What can be done?

Try switching to 3G. The fact is that mobile operators, in most cases, do not provide services abroad in LTE networks. If the problem cannot be solved, you need to contact your operator's technical support.

I accidentally dropped my iPhone from the second floor balcony, after which the network does not always catch me. What is the reason?

The reason here is either a broken antenna or a broken modem. The master will tell you more specifically after a complete diagnosis.

There are many reasons why there is no network signal on an iPhone. In most cases, this is due to incorrectly set Date/Time/Time Zone.

How to fix the error after factory unlock

Most often, iPhone owners encounter this problem after unlocking it using the Ultrasn0w program or updating the modem firmware to the iPad version. But this problem may occur after a restore, update or jailbreak.

If after updating or restoring you see a notification about the absence of a network, it means that your phone has accepted the SIM card, but why it doesn’t see the network is the question. There may be several reasons, let’s consider the main solutions.

You need to reset your network settings. To do this, insert a SIM card that is not supported by the device, go to Settings - General - Reset - Reset network settings.
You can make a backup and delete all the information that is on your mobile device, but this can harm your smartphone.
With the iPhone turned on, remove the SIM card and then turn off the mobile phone. Now insert the SIM card and turn on the phone.
Reboot the iPhone.

Sometimes the network on the iPhone disappears after jailbreak. This is especially true for those models that were initially locked to a specific mobile operator. In this case, it is better to contact a service center, where they can unlock the phone using IMEI. But you must be prepared that this procedure may take several days. It all depends on which operator blocked the network.

What to do when iPhone does not see the network while roaming

The iPhone may lose the network of the cellular operator even when roaming. In this case, it is recommended to switch from 4G to 3G mode. This is due to the fact that cellular operators, in most cases, do not provide services abroad on LTE networks. This can be done in the “Settings” – “Cellular” – “Voice and Data” menu.

Loss of network after replacing SIM card

There are also cases where the iPhone does not see the network after replacing the SIM card. This problem, like the previous ones, can occur in absolutely any model. If this happens, then the first thing to do is take out and examine the SIM card. It can deteriorate if you trim it yourself, if water gets on it, or for some other reason. If it is damaged, it will have to be replaced with a new one. You can check the functionality of the card by inserting it into another smartphone.

In some cases, it helps to simply remove the card and insert it back again. It happens that the network is simply “glitchy”, and such a simple procedure can reboot it. Also, as in previous cases, you can try turning off and turning on your smartphone again, or activating and deactivating the “Airplane” mode several times.

What to do if nothing helps

If no methods help to return the network to the iPhone, you need to contact a company service center. The problem may be very minor and specialists will fix the problem in a matter of minutes after diagnosis. But don’t rule out a hardware failure, in which case repairs can be expensive.

Contacting your telecom operator

Operator or account issues may affect your service. Contact your operator to:

check account activity and status;
find out if there are any service interruptions in your region;
Check to see if cellular services are blocked for your device and if the correct data plan is selected.

Only your network operator has access to and control over your account information. If you can't find your carrier's support page, check the carrier support article or use any Internet search engine.

Additional Information

If a virus has been detected on your device and no antivirus programs help, follow these steps:

Make a backup copy of all account data.

Connect via iTunes to your computer.
Press the back and power button at the same time.
When a recovery message appears in the application, click on the “Restore” button.

Select the file with the appropriate firmware version and wait for installation.

If the iPhone does not find or cannot connect to Wi-Fi, you can independently identify the problem and solve it through self-diagnosis. This will save you time and money, because in most cases the breakdown can be repaired yourself.

But, if after these manipulations your smartphone still cannot connect to the network, do not take risks and take it to a service center.

Be sure to tell us which method helped in your situation. If you know other solutions, please share your experience. Comments and online chat are always open for our readers!

Causes of problems

If the owner has a question about why there is no network on his iPhone, this is the first time he has encountered such a situation. Experienced users already know roughly what can lead to such a situation, and therefore do not panic, but start working.

For beginners, it is important to know exactly why their iPhone does not receive the network, since there is a need to make a call and connect to the mobile Internet. But without a network this cannot be done.

There is more than one problem that causes the iPhone to display the message “No network.” But what exactly it is, we need to find out.

Most often, problems arise for the following reasons:

this is an illegally imported mobile device that is locked to a specific operator;
there was a failure at the software level;
there are problems with the cellular operator;
hardware problems have occurred.

You need to start by looking at the display. The status “Searching” or “No network” may be displayed here. Check for signal. The easiest way to do this is by checking its presence on another device. Before doing this, enable the auto network search function through the iPhone settings.

Additional troubleshooting methods

Other troubleshooting methods that we will consider can be considered universal and provide answers to questions about why the iPhone does not see the Wi-Fi network. Let's look at the most popular ones.

Problems with the module

The hardware module is used to connect to wireless networks. This part is considered one of the most problematic in the iPhone. The problems started with the 4s model, where the smartphone did not see Wi-Fi. Usually the malfunction manifested itself during overheating, falling or moisture getting inside.

In this case, it is recommended to take the cell phone to a specialist, but if you have the appropriate skills, you can fix it yourself.

So, what to do if the iPhone does not see the network at home or any other Wi-Fi:

Turn off your smartphone and remove the case.
Unscrew the screws on the case.
Remove the cover and unscrew the additional 4 bolts next to the camera.
Remove the block and unscrew the screw from the antenna.
Use tweezers to pry the latch and pull it out.

Remove the module and warm it up to 300 degrees. This can be done using a hair dryer.
Warm up the board. We do not recommend holding a hairdryer over it for a long time.
Wait until the device cools down and put it back together.

The solution to the problem is also relevant for the iPad, which does not see Wi-Fi. The same method can be used if you need to replace a faulty part with a new one.

Warming up is a dubious method. Even if you don’t completely ruin your gadget, this method usually only helps for a while. Then the problem comes back.

Reset

Resetting settings is an effective way to fix network connection problems. As we have already found out, connection failures began a long time ago. iPhone 4 did not see Wi-Fi, the story continued with iPhone 5, 6 (at the moment they are not updated). The latest versions have eliminated such problems. If you are the owner of models from previous years, then the reset operation will help.

Be sure to back up your data, otherwise it is almost impossible to restore the information.

How to reset settings:

go to the menu;
find the “Settings” item;
select "Reset";
click "Reset settings";
wait for the operation to complete.

Checking the operation of the router

Relevant if a malfunction in the router is found. Because of this, no device can connect to the Internet via Wi-Fi. This may happen due to power fluctuations or malfunction of some parts.

What can be done:

Try rebooting your router. If the situation has not changed, then use the second option.
Log into your personal account and check your router settings. Login to the settings is done through a browser at 192.168.1.1 (or another one specified on the device itself). Enter your personal password and login from the “admin panel”. Check that the settings are correct.

If this does not help, then try connecting through another device, for example, an iPad. And, if, when you try to connect, the iPad does not see Wi-Fi, then contact the repair service. This is a last resort. Perhaps it's time to change to a new router.

What can cause the radio part of an iPhone to fail?

In addition to a fall, the radio part may fail due to water getting into the device, a malfunction of the modem power controller, transceiver and Rx-Tx amplifiers, a short circuit on the system board, or voltage surges during charging. It is also possible that the soldering of the radio chips is broken. Nevertheless, in all these cases, repair is possible, but not without the appropriate skills and equipment - you can’t change the display in 30 minutes.
