Video instruction

In the world of Apple phones from Apple, not everything is as smooth as the manufacturer portrays. The “No network” error on iPhone is one of the most unpleasant phenomena. Moreover, it appeared on the iPhone 4, then on the iPhone 5 and 5S. And the sixth version did not escape this trouble either.
There are three cases in which this error can appear.

1 The phone was brought to Russia unofficially and locked to a specific operator.
Many who bought an iPhone on EBay or other foreign exchanges encountered this. Due to this, the price of the device is significantly lower. But such a phone will not work without unlocking and will give out this one iPhone error"No network". There is only one way out in this situation - 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 - it’s still Chinese, even though it has the Apple nameplate. First, reboot your phone. If it still doesn’t find the network, then try going into the settings and moving the “Airplane mode” slider back and forth several times:

As funny as it may seem, sometimes it works.

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

There you need to find the slider automatically and put it active mode. If it is already turned on, turn it off and on again. After this, reboot the device.

The reason for the “No network” error appearing on the iPhone may be a settings failure. cellular network. Try resetting them to factory settings. To do this we go to Settings >>> General >>> Reset:

Click on the “Reset network settings” button. The phone will display this confirmation:

Click on “Reset settings”, after which you need to reboot and check whether the network appears.

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

3. Last possible reason- hardware problem with the phone.
Most often - with an antenna. Or a radio module. If the “No network” error on your iPhone appeared after you got it wet or dropped it, then most likely this is what led to the problem. There is only one way out - a trip to service center. I’ll say right away that repairs are usually not cheap, so be prepared for financial expenses.

If your network on your iPhone disappears, don’t get upset and rush to the service center - you may be able to fix the problem yourself. In some cases, to similar problem is not caused by a hardware failure of the phone itself, but software glitch or features of the device settings. First, you need to find out why the network disappears on the iPhone.

Signs of a reception problem

This type of malfunction is quite easy to recognize - the inability to make a call clearly signals that something is wrong with the iPhone. The main signs of problems with the signal will be as follows:

the connection appears and disappears
The network signal disappears when blocked or in the cold
connection does not work only indoors or outdoors
No mobile internet, although the operator's network is working fine

This problem may be caused by problems with the software or operating system, lack of contact with the SIM card (the problem may be in the SIM card itself), hardware failures. But before you look for the root cause of the problem, weed out the most likely options - make sure that your phone is not “locked” to a specific foreign operator(this kind of trouble often occurs among those users who purchased a gadget, for example, on Ebay). If a problem with the network arose precisely because of this, then you cannot do without the intervention of specialists to remove the blocking (to check, just install another SIM). You should also make sure that Airplane mode is not enabled, in which the network will also not work.

SIM card and lack of reception on Apple devices

The simplest root cause of a malfunction is bad contact with SIM card. It may be associated with incorrect cropping of the card under right size. Also, some SIM cards wear out over time and stop working correctly. Characteristic features:

the network appears and disappears
Neither the network nor the mobile Internet works periodically
reception suddenly disappears even during a conversation

There may be several possible solutions. First, try taking the card out of the phone and just wipe it thoroughly - it happens that the contacts oxidize, which can cause reception to deteriorate or simply not work. The second option (if the first did not help) is to replace the SIM card on the iPhone. Before doing this, it is best to check if other SIMs work on your phone (known good ones).

Another Possible Solution problems - resetting settings and getting updates on your iPhone from mobile operator often help troubleshoot network problems.

Incorrect date and time settings

Crashes important programs and applications also cause network problems. In particular, the iPhone loses the network if the time and date are set incorrectly. The sensors get lost when the phone is not used for a long time or when it falls. In this case, the algorithm of actions will be as follows:

connect to any wireless network
open basic cell phone settings
select "Date and time"
opposite the “Automatic” menu item, move the slider to the on position
restart your iPhone

Usually, after this simple procedure, problems with the network disappear - then the device works correctly and receives calls normally. If this does not help, then you can try a hard reboot of the gadget. To do this, follow several steps:

Press and hold the Power and Home buttons for 10 seconds
wait until the Apple logo appears on the display
turn on your iPhone as usual and wait until it connects to your mobile operator's network

If your iPhone doesn't work in the cold

Sometimes in Apple smartphones The network disappears in the cold. Many people encounter this problem iPhone users, but it is not always possible to solve it. For decreasing negative influence It is recommended to disable 3G. In this case, the connection will be lost less often. If reception still does not resume after you get home and warm up your iPhone, try one of the following:

restart your iPhone
check the settings from your mobile operator
turn airplane mode on and off
in the cell phone settings set auto mode network selection

If a solution to the problem has not been found, then it is better to contact specialists. Most likely, the frost simply became a reason for the breakdown, and the root cause lies in mechanical damage(even after a fall from a small height, malfunctions of the antenna or radio module may occur).

When is the best time to take your iPhone to a service center?

The reason that the network disappears on the iPhone may be a hardware failure. So, most often the radio module may fail (for example, after a fall). It is easy to distinguish this type of problem from others

Any modern smartphone is, first of all, a mobile phone, and then everything else. Its most important function is to receive and make calls. To do this, a SIM card with an assigned SIM card is installed in each device. phone number, and a special indicator indicates successful registration in the cellular network and signal strength.

iPhone does not connect to 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 are technically complex devices consisting of several modules built on one system board. These modules operate using complex software. No program or electronic device can boast of 100% reliability - the same applies to the iPhone.

A failure in one module often affects other modules, causing equipment to malfunction. Computer users know very well what to do if a program or the entire PC partially freezes at once - press the reset button. There is even a saying: “Seven troubles – press reset.” And this saying, even though it has undergone modernization, contains some truth - If your iPhone doesn't connect to the network, just try rebooting it.

It is possible that due to some glitch, the device is unable to register with the network, requiring a reboot.

As practice shows, the reboot process really eliminates complex electronic devices from “glitches” and restores their functionality. If your iPhone doesn't see mobile network, try rebooting it - it should work.

Problems finding a network

Your iPhone has stopped receiving the network, although just recently the indicator showed confident reception? It is quite possible that for some reason the smartphone 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 rarely happen online. They appear as a result of some failures on the operator’s side cellular communications or as a result of some errors in your smartphone. You can try to find the network manually or simply restart your device– after that, an automatic search will work in it.

Another reason for failure to select a network may be staying in international roaming. It is quite possible that you tried to register on some network manually, and then forgot to turn on automatic mode. There are also recommendations according to which you need to reboot Cell phones for the most correct registration in your own or a guest cellular network.

Problems with 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 new SIM card with a new number;
Contact a mobile phone store to replace the SIM card while keeping the number;
Try testing another SIM card.

If you suspect that cellular network registration failures are due to problems with the SIM card, try testing your smartphone with a different SIM card. This way you can understand what exactly is involved bad connection with the network.

Don't want to lose your number due to a SIM card failure? Contact your nearest mobile phone store and get a duplicate. Do not forget to take your passport with you, otherwise a duplicate will be denied.

Method number 1 - Take out the SIM card

The lack of an operator’s network causes a lot of inconvenience to users, because the ability to make calls, write SMS, etc. disappears. The first method is quite simple - you just need to turn off the phone and use a paper clip to get sim card from the body. Next, you need to reinstall the card and turn on the device.

This method allows you to prevent temporary interruptions in communication. If the level of cellular communication appears, but changes very often (1-2 sticks are available), problems have arisen on the side of the telecom operator and you need to wait until the signal coming from the towers improves.

Method number 2 – Changing the date and time

Often the correct display of date and time on the phone is lost. As a rule, this happens after replacing the battery. Incorrect date causes a malfunction of individual sites, services, programs and the cellular network. To fix the problem you need to configure the correct settings manually:

Go to “Settings” - “Basic” tab;
Click on “Date and Time”;
In the new window, activate the "Automatic" slider so that the time is regularly synchronized with global network. If automatic setting, for some reason, does not work correctly, configure everything yourself and save the changes.

Method No. 3 – Firmware update or rollback

If the above methods do not bring results, you need to exclude all possible problems, arising in the operating system. Remember when you had problems connecting to cellular communications. Have you installed OS updates before? If yes, you need to roll them back to previous version, because new package contains bugs. You can reset the updates by connecting your phone to iTunes. In the main window, click on the “Restore iPhone” button and follow further instructions.

If you have not installed updates before, the firmware installed on your phone may be out of date. Check for a new OS package in the “Updates” section of your smartphone settings. Install new components over the air and reboot your phone. This will help solve all problems when connecting to the cellular network.

Method number 4 – Enable access to the cellular network

Make sure Airplane mode is turned off on your iPhone, as it will automatically block cellular signal. You should also check the status of cellular data in the gadget settings. Go to Settings-Cellular network. The slider next to the Cellular Data field must be turned on.

Method No. 5 - Replacing the cellular antenna

If the failure is hardware in nature, the only way out– replacement of the cellular antenna. Open the smartphone case, remove the battery and remove the call speaker unit, as shown in the figure:

Remove the screws that secure the antenna to the unit. Then use a spudger to pry off the antenna cables. Next, carefully disconnect it from the part and replace it with a new antenna. Assemble the phone and test the cellular connection.
