This is a common problem for all iPhone models. Depending on version operating system, it appears due to a technical or software failure. In the article we will talk about sources cellular network activation failureiPhone and how to solve the problem.

Possible reasons

The first thing you need to pay attention to is where you purchased the device. This problem occurs more often among people who bought a phone from unofficial suppliers or used equipment sellers. At the first inspection, it is difficult to determine the original condition and performance of all internal modules and adapters.

A used smartphone may not have a communication module that has failed either due to old age or due to improper handling by the previous owner. Unofficial suppliers like to sell reassembled versions of iPhones, which are not made at Apple factories, but somewhere in basements and at the “if only it works” level. Starting with version 11 of iOS, the Apple corporation has revised the rules for using smartphones with non-original parts installed.

In simple terms, if you take your iPhone to a service center, where they promise to make repairs 50% cheaper than elsewhere, unlicensed parts will definitely be installed on your phone. This applies to replacement:

• Wi-Fi modules;
• Nand memory;
• Bluetooth;
• Communication modem.

This is the saddest outcome of events, but there is a more positive one. Cellular network activation failure on a iPhone associated with a software error. For example, during release new version iOS and Apple servers cannot cope with the load they receive and shut down. Activation during this period will not be available because the device will not be able to send the required data. Find out the advantages and disadvantages of iOS in the article: ""

Note: This problem often occurs due to failures on the part of mobile operator. It's very easy to check, try calling another number or checking your balance. If the command does not work and the call is dropped, then the problem is on the operator’s side.

How to solve the error

If mobile communications works, but on iPhone appears cellular network activation failure pdp authentication error, you need to check the functionality of the communication module. On the welcome screen, you need to click on the icon in the lower right corner. An IMEI code should appear; its absence means that the modem is broken. We recommend contacting an official service center. A well-chosen browser will allow you to quickly find a page with the address of the nearest service; we recommend that you read the article: “”

For information: it is possible to revive a smartphone by freezing it in the freezer or heating it with hot air through a hairdryer. The methods are controversial and ineffective.

Other solutions:

If the phone was purchased from a “gray” seller, the options presented above will not work. There is a way to reprogram Nand memory, but only a few people use it and there is no guarantee that the iPhone will work again.

Hello everyone! Mistakes are always unpleasant. And unusual errors are doubly unpleasant. Tell me, is it clear what it means when the message “PDP authentication error” appears immediately after installation? SIM cards on iPhone or iPad? Some kind of continuous set of words - PDP, authentication... Apple, that's enough, stop there already! :)

When I first encountered this problem, I was very puzzled. The SIM card is new and just purchased, the iPad also functions as it should - but when you combine these two variables, you get a “PDP authentication error” and the absence of any mobile internet. Fortunately, you can fix all this yourself and without visiting a service center. How? Now I’ll tell you everything, let’s go!

So what do we see on iPhone screen or iPad besides PDP error? That's right, the message “cellular network activation failed.” This means that there can be three reasons for all this disgrace:

1. iOS Settings.
2. SIM card.
3. "Iron" breakdowns.

We will not consider “hardware”, since hardware problems have slightly different symptoms - a complete absence of a network (and not just the Internet), a different fault text, etc.

But let’s pay closer attention to the first two points. So, what can you do to resolve the “PDP authentication error”:

As you can see, there are plenty of ways and there is nothing difficult - it’s worth trying to do absolutely everything.

I want to focus on the last solution, since in my case this was the reason for the authentication failure. It would seem that there is nothing complicated - go and change your SIM. But that was not the case...

So, we insert a new SIM card into the iPad - we get a failure. We insert it into the iPhone - it works. We install another SIM in the iPad - everything works. Conclusion? The card is faulty. We go to the salon and change it. We insert it again - again an error.

In general, in order not to tell you all my adventures, I’ll go straight to the summary:

The PDP error disappeared after 3(!) SIM card replacements.

This is such an interesting story. Fortunately, a cell phone store is nearby :)

After all this, I made a conclusion for myself - when buying a SIM card, immediately check its functionality (and preferably before paying). Because replacing a card, although free, is still not a very exciting procedure. And if you use this service several times a day, it becomes completely sad.

P.S. As always, I look forward to your comments - tell us about your case, ask questions, recommend an alternative solution to the problem. Write!

If you don't know yet, how to set up internet on iPhone, then be sure to read these instructions. Of course, a lot depends on the mobile operator, which can automatically activate the Internet settings on the iPhone; in this case, just open the standard one, enter the address of any site and check the Internet. If the pages load in the browser, then everything is fine, say thank you to your operator and start surfing the web.

But what to do if the phone does not connect to the network on its own, the answer is to continue reading how to set up the Internet on an iPhone and prepare to enter the settings manually:

Let's go to Settings– Basic– Net– Cellular data network

How to enable or disable mobile internet on iPhone

Enabling and disabling mobile Internet in iOS is done as follows: Settings – Cellular communications – Cellular data. To save traffic and battery power, turn off Cellular data when you are not using the Internet.

We considered how to set up Internet on iPhone using mobile GPRS Internet as an example. But there is another way to connect the Internet to the iPhone - since the phone is equipped with a Wi-Fi module, it is possible to use a Wi-Fi access point, which can be organized at home or use public access points. In large cities, wireless Internet access points are widely developed, so while sitting over a glass of beer in a pub, you can also surf the Internet, check your email or check the weather. To connect via wireless network Wi-Fi needs to be logged in Settings– WiFi and activate the marker, after searching, select one of the found networks.

The disadvantage of connecting via Wi-Fi is that the iPhone is tied to a specific access point; if you move a certain distance away from it, the connection is lost. Mobile GPRS Internet is more convenient in this regard; the Internet works within the cellular coverage area.

If you are interested in high-speed Internet in Apple iPhone and you have already completed the steps above, then look at “ ” and speed up.

If your mobile Internet does not work on your iPhone, you constantly 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, you need to determine the source of the problem as soon as possible and try to eliminate it.

Causes of problems

Before you begin troubleshooting, you need to determine why mobile Internet does not work on your iPhone. It can be difficult to immediately understand the exact reason, so you have to use the method of elimination. Possible reasons include:

• incorrect communication parameters;
• iOS software glitch;
• lack of network coverage;
• problems on the side of the mobile operator;
• problems with the communication module;
• SIM card damage.

Another reason why mobile Internet does not work on an iPhone is the consumption of traffic and the lack of money on the balance to connect to an additional package. Before complaining about other factors, you need to make sure that you do not have any problems with traffic and money.

Checking the connection

First of all, make sure that the mobile Internet is turned on. To do this:

1. Open iOS settings.
2. Go to the “Cellular Communications” section.
3. Move the Cellular Data slider to the On position if it was turned off.

You can also manage cellular data through the Control Center. If the icon is gray, it means there is no connection. Click on it to turn on mobile internet.

Also, make sure that airplane mode is turned off on your smartphone. When activated, all communication modules on the device stop working, so you can’t use calls, messages, or the mobile Internet.

Network reboot

If the cause of the problem is a system malfunction, resetting the network settings will help fix it. It is convenient because when it is executed, user files and settings are not deleted from the phone, that is, there is no need to do backup copy iOS. The only thing that will have to be configured again after the reset is the APN settings for connecting to the mobile Internet.

To reset network settings:

1. Open iOS settings.
2. Go to the "Basic" section.
3. Select Reset.
4. Click Reset Network Settings.

After completing the reset procedure, problems with the Internet should be resolved. However mobile network will not work until you re-add the APN data.

Connection setup

Typically, the connection configuration is added to the phone when it is turned on for the first time. If you reset your network settings, you will have to order APN data from your operator again or enter it manually in the settings.

Beeline Internet problems

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

1. Open settings.
2. Go to the Cellular Data section.
3. Go to Cellular Data Settings.
4. Click APN Settings.

Each operator has its own APN parameters. You can view them on the official website of the cellular provider. For Beeline you need to enter the following settings:

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

There are not many differences between other operators. For example, MTS uses APN internet.mts.ru with the username and password mts. In addition, if you have problems with the mobile Internet, you can call the operator’s support service - for Beeline subscribers it works at 0611. From the support service you can order mobile Internet settings, which will come in a 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 detection provider. If your phone connects to the wrong operator, configure this setting manually.

System errors also affect connection stability. For example, if you set the wrong date in the settings, the phone may stop receiving the network. System crashes can often be resolved by simply rebooting the device. As a last resort, you have to resort to a hard reboot and reset.

Hardware faults

The most unpleasant problem that an iPhone owner may encounter is damage to the communication module. If a broken SIM card can be quickly and free of charge replaced at the office of a mobile operator, then repairing or installing a new module will cost much more.

A failure 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;
• antenna failure;
• failure of the SIM card holder or connector;
• damage to the radio path.

Open the iOS settings and see if there is a “Modem Firmware” item in them. Its absence indicates that the transmitter power amplifier is broken. Unfortunately, not all hardware problems are so easy to detect. To diagnose damage to the radio path, you must contact a service center. The cause of the problem may be a faulty lower cable. The problem can only be fixed at a service center by replacing the damaged component.

If the iPhone is constantly searching for a network, you should pay attention to the condition of the antenna. It may fail after the smartphone is dropped, subjected to a strong impact, or comes into contact with moisture.
