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 the 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 have gone astray cellular operator... 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 data network". 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. In case of mismatch, 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 weak signal lies in the fact that the user's place of residence is not included in the GSM coverage area, the problem cannot be corrected on your own. You will have to buy a SIM card for temporary use. Although in fact the territory where utterly there is 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-surfing the Internet. The "jammers" look like this:

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

If GSM signal weakened 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 who suffers 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 owner of the iPhone 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 be in the software. For the gadget to work correctly, the latest system updates are required. To check if there are any 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. Estimated prices put together in a plate:

It is recommended to remove the SIM-card and make sure that we have a really branded SIM card of the cellular operator. In addition, you should check it for mechanical damage. Now insert the SIM card, turn on / off the "Airplane" mode several times - the signal should appear.

Fortunately, most cellular data problems on iPhone are very easy to fix. This is often done by changing one or two options. Below we will tell you what to do if the mobile Internet does not work on the iPhone.

How to fix cellular data problems on iPhone

Here are six ways to fix cellular data problem on iPhone. The first of them should solve most of the problems when, for no apparent reason, the mobile Internet simply stops working.

1: Check Cellular Data is On

The first step is to check that the Cellular Data option is enabled. You may find this advice silly, but you have no idea how often people accidentally turn off their cellular data or turn on airplane mode. This is now happening even more often due to the Cellular Data icon in the iOS 11 Control Center.

Check Cellular Data:

1. Open Control Center.
2. Make sure the Cellular Data icon is on (it should be green).

If the icon was gray, then Cellular Data was disabled.

1.1: Don't forget to check Airplane mode

Do not close Control Center and immediately check that Airplane Mode is turned off. This mode turns off all communications, including cellular data, so it may well be the cause of the problem. If Airplane Mode is on, turn it off.

The Cellular Data option can also be checked through Settings, just like Airplane Mode.

1. Open Settings.
2. The first section will be Airplane Mode. Make sure the switch next to it is off.
3. Then go to the Cellular section.
4. Make sure the toggle next to Cellular data is turned on.
5. Also check that cellular data is enabled in the apps you use frequently. To do this, scroll down the screen and check the switches.

These two options are the most common causes of problems with mobile internet... When something is wrong with them, you can make and receive calls, but the Internet does not work. We strongly recommend that you check them first.

You can also turn off access to cellular data in applications where they are not needed. This will help save traffic.

2: reset network settings

Some network problems can be resolved by resetting the network settings and rebooting. The only problem this method in that all saved settings will be erased, such as DNS, as well as passwords from wi-fi networks.

1. Open Settings.
2. Go to General and select Reset.
3. Click Reset network settings and confirm the action.
4. Close the settings and reboot the device.

When the iPhone turns on, open an app like Safari and check if the internet is working.

3: Check for operator updates

Sometimes providers provide operator updates. If you do not install such updates, there should be no problems, but there is no reason to avoid them either.

1. Open Settings and go to General.
2. Select About this device. If an update is available, it will automatically appear on the screen and you can install it.

4: Update iOS

Updating the system to the latest available version can also help. IOS Updates contain various bug fixes and system improvements. Sometimes they can solve cellular data problems as well.
