Although you can take the first and quite simple steps on your own, but only if you have a clear idea of ​​what to do.

    If a situation in which it is impossible to activate the iPhone has arisen already during its active operation, it is worth considering what actions could provoke this problem.

A hardware failure may reflect, for example, a modem problem or inoperability. Finally, such a “diagnosis” should be made and a solution should be found by a specialist of the service center. Software errors are usually resolved by reinstalling the iOS system.

The second, most correct decision is to contact the service center of our company, since it is better to trust the professionals to solve serious problems.

    There are several other reasons preventing iPhone activation. Firstly, the absence of a SIM card, or its incorrect installation in the SIM tray, reinstalling this necessary element will solve the problem. Secondly, this procedure requires a stable signal of the used network of the selected operator, as well as the presence of an Internet connection. IPhone activation lock is also possible if the smartphone has already been linked to another iCloud account and it has not been eliminated. Most often, this situation occurs if the smartphone already had another owner. The problem of unlocking the system is being solved, for which the owner must enter the personal identifier of the previous user and his password. And finally, a fairly new, but very serious problem, the so-called “iOS 11 syndrome”. It consists in the fact that after the appearance of iOS 11, Apple introduced control over the repair of the iPhone.

Some can be eliminated by the user on his own, others can actually be eliminated only at a service center.

    IPhone 4, 5, 6, 7 activation failed. what to do

    The key difference between smartphones from Apple and all similar ones is a close relationship with the manufacturer throughout the entire life of the gadget. All services provided by it are possible only with an activated device. However, the user may face a problem when the iPhone refuses to go through the activation procedure, making these functions unavailable.


    iPhone may refuse to activate after a factory reset has been performed on the device. A similar problem is observed on iPhones with iOS 11 and higher, which have been repaired in an unofficial service. In such workshops, non-original components could be installed on the device.

    Another case. the smartphone was bought from hands, while its origin remains a mystery with seven seals. Assembled do not understand from what in a semi-handicraft way, such a device, after resetting the settings for activation by a new user, may not pass it and become completely inoperable.

    What is activation failure on iPhone 4, 5, 6, 7 and other models

    When the message “Unable to activate iPhone” is displayed, the owner of such a device faces a problem. The fact is that in this case it will not be possible to use the gadget to the fullest: make calls, send messages, there will be no possibility of data synchronization and OS updates.

    Hardware problems

    The worst reason is that the modem is faulty, which is responsible for the activation. Only contacting the service center will help here, since it is not impossible to solve this problem on your own, but simply dangerous. After such a repair, you can finally break the device.

    Internet connection problems

    Lack of Internet connection may cause iPhone activation to fail.

    Note! In addition to traditional networks, some wireless Wi-Fi can block the gadget’s attempts to activate.

    • some gadgets from Apple can only work with a SIM card of a certain cellular operator. Such devices are usually called contract or gilded. You can find out if this is so on specialized sites (for example, at;
    • some devices may display an “Activation Failed” message due to the fact that they could simply freeze;
    • a possible reason can also be the performed procedure of updating the firmware version to the latest version or restoring;
    • there are iPhones on which the beta version of the firmware is installed. Such a gadget cannot be activated because it is not registered with Apple.

    Restart iPhone

    You can try hard restarting your iPhone. To do this, you need to hold down the shutdown button and the “Home” key for a few seconds until the device turns off. After that, you need to turn it on and try again to go through the activation.

    Important! On those smartphones that do not have such a key, the “Volume Down” button is used.

    IPhone Activation Failed. Everything Is Very Bad

    Why does the title say that everything is very bad?

    Because, it is quite possible that the modem in the device “died”.

    Indirectly, this can be confirmed by the fact that by connecting the gadget to a computer and iTunes, absolutely nothing happens. no activation or something even remotely similar to it.

    There is another way to test this terrible guess.

    On the welcome screen, click on the “letter i in a circle” icon.

    After clicking, on a normal and working iPhone, the serial number of the device should appear. If IMEI does not appear, but only standards are written, etc. then I have bad news, the modem in your iPhone or iPad has ordered a long life. Naturally, with such a malfunction, the device cannot be activated. What to do?

    • Contact the service, the repair price is not very high (relative to the cost of the device), but they undertake such a repair of the unit and no one gives guarantees.
    • You can try to put it in the freezer (at your own peril and risk!), There is a possibility that the contacts will stand “as it should” at least for a while, and it will turn out to activate it.
    • Warm up with a hairdryer (also at your own peril and risk!). the effect is similar to freezing (it may or may not appear).

    It must be understood that the last two points are, of course, a fierce “collective farm” and they should be carried out very carefully. But it helps some. By the way, updating the firmware on such gadgets is useless, during this operation you will get an error.

    All that is described above is not your case? Is IMEI displayed and is the modem OK? Moving on to the next item!

    IPhone Activation Failed. Server Unavailable or Worse?

    Hey! It doesn’t matter what you did in order to get the activation failed error. We reset the content and settings, flashed it, performed an update, recovered. any of these actions leads to the fact that the device must be reactivated. Yes, yes, yes, you will have to go through exactly the same procedure again as when you first turned on the gadget. And here one very large and large ambush can await us.

    An iPhone or iPad can easily warn you that activation is impossible, because: “Your iPhone could not be activated because the activation server is temporarily unavailable. Try connecting your iPhone to iTunes to activate, or try again in a few minutes. If the problem persists, contact Apple Support: “.

    It would seem that everything is very logical. The server is unavailable, Apple has problems, we wait until the failure passes and we swear at the company. However, not everything is so simple.

    And in general, if you are faced with such a message, then I will have two news for you, good and bad. And we’ll probably start with a bad one

    iPhone on iOS 11 and iOS 12 won’t activate after factory reset

    This text is an update to the article after the release of iOS 11.

    We have already discussed this situation in the Комментарии и мнения владельцев, but for those who are too lazy to read, here is a short excerpt from all this.

    Since the release of iOS 11, Apple has changed its policy regarding unofficial iPhone repairs. If non-original components were installed in the device, then after the procedure for resetting the settings and content, you can get a “brick”. it will be impossible to activate the phone.

    Who is at risk? Devices (running iOS 11 and iOS 12) that:

    • Have ever been repaired (with replacement parts. Nand-memory, modem, Wi-Fi and Bluetooth module) in unauthorized service centers.
    • They are the so-called “handicraft restored” iPhones (smartphones assembled by someone who and where). unscrupulous sellers very often sell them under the guise of new.

    During the power-on phase (after a factory reset and content reset or a firmware restore), the iPhone sends data about the components installed inside it to Apple servers. If this information does not match the base of the “apple” company, then activation of the device is blocked.

    So, what exactly is this to do now??

    • If there is a guarantee. use it.
    • Some unofficial service centers may try to solve this problem with special equipment. But, as a rule, no one gives any guarantees. even if the activation failure can be “bypassed” now, then in the future everything can happen again.

    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 is to blame or

    In fact, failure can occur for a variety of reasons. And the right decision would be to check everything in order, let’s go!

    • Check if the SIM card is inserted and is it working? The advice is of course very obvious, but everything can happen.
    • Make sure you have internet access again.
    • Apple servers are unavailable. how to check their status at the moment? This often happens on the days when new versions of iOS are released. Many people around the world are trying to get a new firmware as quickly as possible and the servers simply cannot withstand such an influx of people. In that case, you just need to wait
    • Use a different internet connection. Some Wi-Fi networks can be configured to block access to Apple servers.
    • Use iTunes to activate (be sure to update it to the latest version!)
    • Hard reset your iPhone or iPad. Hold down the Home and Power buttons. do not release them until the iPhone turns off.

    By the way, the reason for Activation Error may be the fact that a beta version of the firmware was installed on the iPhone, and the device was not registered in the developer program. In this case, the error text 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 ( and register the gadget.

    As you can see, the reason that the iPhone refuses to activate and crashes can be a variety of situations:

    • From commonplace. lack of Internet, unavailability of servers, “bugs” in iOS.
    • To very difficult ones. a breakdown of the modem and the newly minted “iOS 11 syndrome”.

    And if the first ones are solved quite simply (wait, change the SIM-card, etc.), then the second (“iron” problems) are corrected only with the participation of a competent service center specialist. But I, as usual, sincerely hope that this is not your case.
