If your mobile Internet is not working on the iPhone, constantly you have to look for an open Wi-Fi point to connect to the Internet. There is little pleasant in this situation, so if any problems occur, it is necessary to determine the source of the problem as soon as possible and try to eliminate it.

Causes of problems

Before proceeding to troubleshoot, you need to determine why mobile Internet does not work on iPhone. It is difficult to understand the exact cause immediately, so you have to go using the exclusion method. Among possible reasons:

incorrect communication parameters;
iOS software failure;
lack of network coverage;
problems on the side of the mobile operator;
malfunctions in the communication module;
damage to the SIM card.

Another reason, because of which the mobile Internet does not work on iPhone - the consumption of traffic and lack of money on the balance for connecting additional package. Before comparing other factors, you need to make sure that you do not have any problems with traffic and money.

Check compound

First of all, make sure the mobile Internet is included. For this:

Open iOS settings.
Go to the "Cellular Communication" section.
Turn the "Cell data" slider to the "enabled" position if it was turned off.

You can also manage cell data transmission through the control center. If the gray icon means there are no connections. Click on it to enable your mobile Internet.

In addition, make sure that the airrest is turned off on the smartphone. When it is activated on the device, all communication modules stop working, so it is impossible to use any calls or messages nor mobile Internet.

Reloading network

If the cause of the problem has become a failure of the system, reset will help to eliminate it network settings. It is convenient because when it is executed from the phone, user files and settings are not deleted, that is, no need to do backup iOS. The only thing you have to configure after resetting the APN parameters for connecting mobile Internet.

To reset network settings:

Open the iOS settings.
Go to the "Basic" section.
Select "Reset".
Click "Reset Network Settings".

After completing the reset procedure, the problem with the Internet work must be eliminated. but mobile network Will not work until you re-add the APN data.

Connection setup

Usually, the connection configuration is added to the phone when you first turn on. If you drop the network settings, you will have to order the APN data from the operator again or prescribe them in the settings manually.

Internet problems Beeline

If a mobile Internet from Beeline on the iPhone does not work after resetting the network settings, follow these steps:

Open settings.
Go to the "Cell data" section.
Go to "Cell data parameters".
Click "APN Settings".

APN parameters for each operator their own. You can see them on the official website of the cellular provider. For biline, you need to enter the following settings:

APN - internet.beeline.ru.
Username and password - Beeline.

Other operators have no difference. For example, an APN Internet.mts.ru is used on MTS with the username and password MTS. In addition, when problems with mobile Internet, you can call the operator's support service - for the Beeline subscribers it works at 0611. In support service, you can order the mobile Internet settings that will come in the configuration message.

System failures

It is important that the correct operator is selected in the settings, otherwise the iPhone will not receive a signal. For convenience, it is recommended to enable automatic definition of the provider. If the phone is connected not to that operator, configure this parameter manually.

Affect the stability of the connection and system errors. For example, when installing an incorrect date in the settings, the phone may stop catching the network. System failures can often be eliminated by a simple restart of the device. In extreme cases, you have to resort to a hard reboot and resetting the settings.

Hardware fault

The most unpleasant problem with which the iphone owner may occur - damage to the communication module. If a broken SIM card can be replaced quickly and free to replace in the office cellular operatorThe repair or installation of the new module will cost much more expensive.

The breakage of the communication module is characterized by the absence of an operator signal. Communication may be lost for the following reasons:

damage to the transmitter power amplifier;
breakdown antenna;
failure of the holder or the SIM card connector;
damage to the radio paint.

Open the IOS settings and see if they are the "modem firmware" item. His absence says that the transmitter power amplifier is broken. Unfortunately, not all hardware faults are so easy to detect. To diagnose the damage to the radio, you must contact the service center. The cause of the problem may be faulty lower loop. You can fix the problem only in the service center by replacing the damaged component.

If the iPhone is in mode permanent search Networks should pay attention to the antenna state. It can be out of order after the fall of the smartphone, a strong blow or contact with moisture.

Hey! It doesn't matter what you did in order to get an error of activation failure. Reset the content and settings, have been stitched, fulfilled the update, recovered - any of these actions leads to the fact that the device must be activated again. Yes, yes, yes, you will have to pass exactly the same procedure as the first inclusion of the gadget. And here we can raise one very big and large ambush.

the iPhone or iPad is easily able to warn that the activation is not possible, because: "Your iPhone failed to activate, since the activation server is temporarily unavailable. Try to connect the iPhone to iTunes to activate or try again in a few minutes. If the problem is not eliminated, contact Apple Support: Apple.com/ru/Support.

It would seem that everything is very logical. The server is unavailable, Apple has problems, waiting for a failure and swearing on the company. However, not everything is so unequivocal.

And in general, if you encountered such a message, then I will have two news for you, good and bad. And let's start with a bad ...

IPhone activation failure - everything is very bad

Why is the title written that everything is very bad? Because, it is quite possible "died" modem in the device. Indirectly, it can be confirmed by the fact that connecting the gadget to a computer and iTunes, absolutely nothing happens - no activation or something, at least remotely similar to it.

There is another way to test this terrible guess, press the "Letter I in a circle" icon on the welcome screen.

After clicking, on the normal and working iPhone, it should appear serial number Devices. If IMEI does not appear, but only standards are written, etc. I have bad news, a modem in your iPhone or Aipad ordered a long time to live. Naturally, with a similar malfunction, the activation of the device is impossible. What to do?

Contact your service, the price of repair is not very large (relative to the cost of the device), but no one gives for such repair of the unit and guarantees.
You can try to put in the freezer (at your own risk and risk!), There is a possibility that contacts will be "as it should" at least for a while, and it turn out to be activated.
Warm hair dryer (also at your own risk!) - The effect is similar to freezing (it can manifest itself, and maybe not).

It is necessary to understand that the last two points, it is of course the "collective farm" and perform them very carefully. But some helps. By the way, to update the firmware on such gadgets is useless, during this operation, get an error.

All that is described above is not your case? Imei is displayed and modem is normal? Go to the next item!

iPhone on iOS 11 and iOS 12 is not activated after resetting settings

This text is updating the article after the release of the iOS 11 firmware.

We have already managed to discuss this situation in the comments, but for those who are too lazy to read, here's a brief excerpt from all this.

The essence of the problem:

From the output of iOS 11, Apple has changed its policy regarding the unofficial repair iPhone.. If unoriginal components were installed in the device, then after the procedure for resetting the settings and content, you can get a "brick" - activate the phone will not be possible.

Who is in the risk zone? Devices (running iOS 11 and iOS 12), which:

Ever repaired (with replacement of spare parts -, modem, Wi-Fi and Bluetooth module) in unauthorized service centers.
These are the so-called "hand-restored" iPhone (smartphones collected in incomprehensible by whom and where) - unscrupulous sellers are very often selling them under the guise of new ones.

What's happening?

At the inclusion step (after resetting and the content or firmware recovery), the iPhone sends data about the components installed inside it on the Apple server. If this information does not coincide with the database of the "apple" company, then the device activation is blocked.

So, and what about this now to do?

If there is a guarantee - use it.
Some unofficial service centers may try to solve this problem using special equipment. But, as a rule, no one gives any guarantees - even if the activation failure will be able to "go around" now, then in the future everything can happen.

Here is such a sad story. However, it is not at all necessary that the error occurs precisely because of this ...

iPhone failed to activate - the server or ...

In fact, failure can occur by different reasons. And the right solution will check everything in order, went!

Check if the SIM card is inserted and is it working? The advice is certainly very obvious, but everything happens.
Make sure that you have access to the Internet.
Apple server is not available - in this moment? This often happens in the days of the release of new versions ios.. Many people around the world are trying to get as quickly as possible. new firmware And the server simply does not withstand such an influx of those who want. In this case, you just need to wait ...
Use another Internet connection. Some Wi-Fi network Can be configured so that you block access to Apple servers.
Use iTunes to activate (required!)
Make hard restart iPhone or iPad. Clamp hOME buttons And POWER - Do not let them out until the iPhone turn off.

By the way, the reason for Activation Error can also become the fact that the iPhone has been installed a beta version of the firmware, and the device was not registered in the program of developers. In this case, the text of the error will be like this:

This Device Is Not Registered AS Part of the iPhone Developer Program ...

In this case, you need to go to the Apple Developer Portal (developer.apple.com) and register a gadget.

As you can see, the reason for the iPhone when activating gives a failure, there may be a variety of situations.

From banal - the absence of the Internet, to very complex - breakdowns of the modem and the newly-made "IOS 11 syndrome". And if the first are solved quite simply (wait, change the SIM card, etc.), then the second ("iron" problems) are corrected only with the participation of a competent specialist service Center. But I sincerely hope that this is not your case.

P.S. Write questions in the comments, as well as the secret scheme for you ... To successfully activate the iPhone - you just need to put a "like" to this article. Test!
