Quite often, inexperienced iPhone users (as well as other smartphones) face the problem of receiving incoming calls. More precisely, other devices simply cannot get through to the subscriber, and this can happen for a number of reasons, which complicates the diagnosis.

In this guide, we will list the most common situations that lead to blocking of incoming calls on the iPhone, as well as how to resolve them.

Can't get through to you - Do not disturb and Airplane mode are on
Perhaps the most common case is that the user lifts the "shutter" of the Control Center and accidentally activates "Airplane mode" (a button with an airplane image) or "Do not disturb" (a button with a crescent moon), after which it becomes impossible to reach the subscriber.
If you call a contact whose "Airplane mode" is activated, the receiver will tell you that "the subscriber's device is turned off or is out of the network coverage area."

If you call a contact who has the Do Not Disturb mode activated, no matter how many calls you call, the handset will always be busy (in detail)

The activation of these modes will be notified by the corresponding icon in the status bar of the desktop, and you can disable them in the same Control Center or in the main settings menu. Also note that the Do Not Disturb mode can be activated automatically at a certain time of the day, if such a condition is specified in its parameters.
For more details on how the Do Not Disturb function works, see this article.

Can't get through to you (or you) - Teletype or Virtual TTY is on
Sometimes, while exploring the capabilities of a smartphone, a novice user resembles a puppy in a new apartment - he tries all the possible functions, options and modes that he finds in the settings. The result is usually unpleasant, but easily reversible consequences. For example, you may not be able to reach your iPhone if you activate the TTY feature (designed for people with limited or total hearing loss) in Settings → General → Accessibility → TTY. The activation of this function will also be indicated by the icon at the top of the home screen.

They can't get through to you (or you) - check the "Black List"
In the case when only one or several subscribers cannot get through to you, especially if it is an ex-boyfriend or an annoying work colleague, then it will not be superfluous to check the list of blocked contacts.

To delete a person from the “black list”, go to the menu “Settings → Phone → Blocking and ID. call ", make a left swipe to the contact you want to amnesty, and press" Delete ".

Determining the number
In the settings of the standard “dialer” application in the iPhone, there is also an option “Show number”, when deactivated, you can make calls anonymously. However, such secrecy often has the other side of the coin - the operator or network settings of other subscribers may prevent them from dialing your iPhone.

However, many users complain that the "Show number" option turns off spontaneously after restarting the iPhone. To make sure that it is active, you should find the corresponding item in the "Settings → Phone" menu.

Tweaks, bugs, crashes
Naturally, there are still a whole host of very rare, but still probable reasons for blocking incoming calls. These can be incorrectly configured jailbreak tweaks, errors in the test version of the operating system, third-party plugins with user-signed certificates, etc.
If you cannot determine the exact cause, then you should reset the network settings, reset or reinstall (restore) iOS, using our detailed guides, if necessary.

SIM card problems and carrier settings
You cannot get through even after a full flashing of the iPhone through recovery. In this case, you need to make sure that there are no problems with the SIM card itself (the easiest way to do this is by installing it in another phone), and also contact the operator that provides mobile services.

IPhone hardware problems
If all of the above possible reasons for blocking incoming calls and methods for solving the problem have been tested, but have not yielded results, then there is probably a hardware failure of the smartphone. We highly do not recommend to solve such problems on their own with the help of an improvised tool for novice users - in most cases, contacting a service center will save your time and save the iPhone from additional damage.
