Reset network settings

We go to “Settings”. “Basic”. “Reset”. “Reset network settings”. Restart your device and give it a couple of minutes, after which iMessage and FaceTime should work.

Disable / Enable services

Well, everything is simple. Just turn off iMessage and FaceTime, wait a few minutes, and turn off again.

Set information about yourself

  • Go to “Settings”
  • Section “Mail, addresses, calendars”
  • Scroll down and select “My data” in the “Contacts” section
  • Choose yourself there, yes, just yourself

Fixing iMessage and FaceTime activation issue in iOS 7

The problem of activating Apple services iMessage and FaceTime quite often became a stumbling block for a number of users. And now, after the release of iOS 7, it again surfaced on the net and multiplied on the Apple support forum. Basically, this problem manifests itself as an incredibly long “Waiting for activation”, but sometimes it can lead to errors. There are several ways to solve this problem, which we will tell you about today.

Method “bezimochny”

  • Disable iMessage / FaceTime (Settings. Messages / FaceTime. Off)
  • Removing the SIM card from the phone
  • Turn on iMessage / FaceTime (Settings. Messages / FaceTime. On)
  • Add your e-mail (Apple ID) as an address for calls / messages, if not added.
  • Insert the SIM card into the phone.
  • Two windows will pop up about possible debiting of funds. REFUSE in both windows.
  • You can now make FaceTime calls and send iMessage messages. But in order for your friends to be able to fully reach you via iMessage / FaceTime, they will need to add your e-mail (Apple ID) to their address book.

Well, as an option, there is a reboot. If none of the above methods helped you, then try reflashing the device. If this does not help, then contact the operator or service center.

Guys, I have iPhone 4s, iOS 9.3.5 and Face Time and ıMessage are not activated, they constantly give an error, who has come across or knows the solution?

helped reset network settings, operator beeline

Hello. I’m having some kind of problem with iMessage and FaceTime. I was on the Beeline operator, in November I switched to MTS with the same number. Temporarily did not use these functions, now they are needed. The problem is iMessages are not sent from my phone number, but from my email. And friends who write to me on iMessage, as if they can not send me messages, but I get them. There is a check mark next to the e-mail; there is no way to delete it, there is no check mark in front of the number. I tried to reset the network settings, even completely reset the phone. In MTS they said nothing blocks me from their side. Maybe iMessage still fixes my number as Beeline, and not MTS? Help me please!

topped up the account with 25 rubles and it worked

Anton, then you have a device from the OEA or those places. there facetime is cut from the system.

I have a phone from the UAE, how can I flash it or what to do to get it installed??

Anton, which model is in the settings? Settings-General-About this device. Model. What is written there?

Anton, then you have a device from the OEA or those places. there facetime is cut from the system.

bought in Russia in CSN, how is this possible?

Anton, then you have a device from the OEA or those places. there facetime is cut from the system.

Pavel, install the latest firmware and check the settings again.

The same problem, the latest version of iOS 9.2 is installed, also there was no facetime on iOS 8

Pavel, install the latest firmware and check the settings again.

And I have a problem of a different nature. There is no FaceTime item in the settings at all and there is no such application. Model code MB297B / A. Help!

I climbed all the links, tried everything I could (I replenished my account with 10 UAH and it all worked

Bullshit! When resetting the network settings, all saved WI-FI passwords were deleted: evil:

nothing helps iPhone 6 some kind of trouble

And I don’t have me in my data What to do?

And I don’t have me in my data What to do?

Thanks, the method with resetting network settings helped! : woot:

I found such a solution: as it turned out, if you log into your Apple ID not from your phone but from the epl website, then there is a time zone button or something like that. So, it is there that you need to change the time zone to your own (as well as in the phone) and after that restart the phone and activate iMessage again

I recently bought a Mac, set up iMessage and FaceTime there, after a couple of days these programs stopped working on iPhone (4c) and iPad. At the same time, when I make money to activate the program, it does not even allow me to write a password, just an endless wait for activation. How to solve my problem?

iPhone 5S, iMessage does not come to me. ;-( Everything is turned on correctly, I successfully send iMessage, it seems that they are delivered, I see that they have been read, but I do not receive answers. On-Off re-turned on-off, the phone rebooted the effect to zero. Help please!

I wanted to use the facetime, but there I did not find my region, and most importantly, my country, there is no Kazakhstan there. You people, what are you? there is even Tajikistan and Kyrgyzstan, but there is no Kazakhstan !! Correct the error immediately. This is such a shame! : straight:

I ran into a problem today! I have not used the ipad mini for a long time today and turned it on and it constantly asks for a password for imessage, I enter the previously created password, and it says that it is wrong. Help!

iMessage: messages come from the sender’s email, not the phone number, how to set up to be sent to the NUMBER? tried to log out and log in Apple ID, but still the same problem, NUMBER and e-mail appears. but the number is not ticked I don’t know why, there is still an e-mail. tell me. thanks in advance.

I did as everything is written here, added myself, then dropped the network data and everything does not work exactly. Tell me what to do?

turn on cell transmission. data for customization

In my message settings, in the field, select the region, my country is not Kazakhstan is not! How so?!

Victor, go to the settings, rezdel iCloud, swipe down and turn off find the iPhone, enter the AppleID login-password and that’s it.

Help plizzzzzzzz. formatted the bodies “reset settings” and it asks for the ID I drive, it writes it is not possible to unlock! Something to do with “FIND iPhone” iPad is tied to it but it is broken! what to do bodies need urgently!!

I can’t send a message, tell me what I’m doing wrong?

the first time I try to use imesage and I can’t turn it on in any way, I’ve already tried everything ………….

And if you enter another Apple ID on the iPhone and and set the send / receive to email, and not to the phone number, is it possible to receive messages sent to another Apple ID?

I have an iPhone 5 but there is no facetime anywhere, neither in the main menu, nor in the settings. help me please!

VeriSign Class Secur for iphone4S was issued before June 2, 2022. so why did FaceTime end so quickly after 2 years and why Apple imposes updates to 7. and there is no return to version 6 at all?

So I have already been updated to the seventh version for a long time and I accept all updates. But it doesn’t work. This is not the reason.

The reason is just this! Without the latest firmware version, Apple technical support won’t even talk to you!

How to enable FaceTime on iPhone, iPad and iPod Touch

You need to go to Settings. FaceTime;

Click the “Your Apple ID for FaceTime” button, enter your Apple ID information, and toggle the FaceTime checkbox active so that “Waiting for activation” appears;

You must wait until the activation is completed and, if necessary, complete the fields below.

How to enable, set up, and use FaceTime on iPhone, iPad, and iPod Touch

FaceTime technology allows iPhone, iPad, iPod Touch and Mac users to make free audio and video calls, while paying only for the Internet traffic they consume. Like the iMessage instant messaging service, FaceTime is disabled by default in the iOS operating system, below you will find detailed instructions on how to activate and use it.

So, for the first time Apple presented FaceTime for iOS at WWDC in June 2010 along with the iPhone 4, and in October the company announced support for Mac OS X Snow Leopard. Thus, users of Apple devices were able to communicate face-to-face for free, as well as broadcast video from an iSight camera for the interlocutor and make voice calls using a regular Wi-Fi or DSL connection, and in 2012 support for 3G / LTE standards also appeared. Since then, thousands of Apple device owners from all over the world (not counting a number of Arab countries) use FaceTime every day.

In terms of making audio or video calls, FaceTime is analogous to Skype, Viber and other instant messengers.

The main benefits of FaceTime include:

  • no need to install additional applications. FaceTime is available immediately in iOS.
  • full integration with the Contacts application.
  • high quality communication.

The main disadvantage of FaceTime is the lack of cross-platform. the service is available only to users of Apple devices (iPhone, iPad, iPod Touch and Mac).

How to make FaceTime calls on iPhone, iPad, and iPod Touch

You can make a FaceTime call directly from your subscriber card in the Phone app on your iPhone. By clicking on the desired contact, it remains to select an audio (handset icon) or video call (video camera icon).

If there are no FaceTime icons in the selected subscriber card, this means that the user you are going to call has not activated (activation instructions above) the service on his device.

During a FaceTime call, you can mute, switch from the front camera to the main camera, change the display orientation, and more.

We talked in more detail about using FaceTime (about the difference between FaceTime audio and FaceTime video, etc.) in this article.

You can also make calls via FaceTime using the app of the same name in iOS.

In addition, FaceTime Continuity technology enables regular cellular calls from non-cellular devices, such as Macs or iPads (Wi-Fi Only). How to do this is described in this material.

Can someone else cheat Face ID, sculpture, 3D model?

The answer should be no, based on Apple’s approach of data points, infrared scanning, and attention function. People tried to cheat Face ID using photographs, plaster models and other methods. But the plaster model does not reflect the same as a 100 percent identical human face, because infrared radiation reflects living skin differently than with inanimate material.

In Apple’s documentation, it says it introduces randomness to make it even more complex. The sequence of 2D infrared scans and captures of depth-map points is sent in random order, and the design point template is random and unique for each device. This makes it harder for an attacker to use predictable elements to trick the scanner.

The white paper with the face ID tag notes that while there is a primary neural network that performs the identification, the second neural network checks for forgery by looking at the photo indicators and masks.

What should I use Face ID for?

For purchases from Apple Pay, the App Store and iTunes, and third-party apps that currently rely only on Touch ID. Apple says third-party apps with Touch ID will be able to enable Face ID authentication.

Interestingly, Apple says that developers can use Face ID without using a password if the developer wants to use biometric identification as a kind of second factor that cannot be circumvented.

How to Unlock iPhone X Using Face ID

You need to activate the screen of your device.

Now look at the screen. Be sure to keep your eyes open when unlocking your device.

How to set up Face ID, full set up on iPhone X

Face ID is a form of biometric authentication. Instead of a password, security key or Touch-ID to protect (from unwanted viewing of your data), biometrics is your unique identifier (Unique fingerprint or face snapshot). Fingerprint recognition is also biometric. How to set up Face ID on iPhone X?

Open up. to quickly find the material you need!

What devices does Face ID support??

So far, only the iPhone X is planned to implement Face ID. It will also be in new phones or even Apple’s iPad.

How to set up Face ID correctly on iPhone, setting up Face ID?

Face ID uses a “Registration” process just like Touch ID.

iPhone X Face ID Setup and Testing!

First go to “Settings” “Face ID and Password” and click “Save”.

The iPhone will then turn on the front camera, displaying your face in a circle with green markings surrounding it. Registration software will overlay 3D markings on the screen to show your line of eyes and face.

You need to roll your head in a circle for Face ID to scan your face.

How to set up Face ID

After your face is successfully captured, you will be asked to set a backup access code if you haven’t already, so follow the instructions to take care of this.

When you’re done, you can unlock your iPhone using your face. To get started, turn on the device by pressing the side button. Then just look directly at the device with your eyes wide open. If you follow the instructions correctly, your iPhone X will be unlocked. You can now freely go to the home screen.

When you need to enter a passcode to unlock iPhone X?

After 48 hours of not using Face ID on your smartphone, you will have to use a passcode.

After restarting your device, you will need to use a passcode.

An eight-hour timer is automatically set every six days. And if you are not using Face ID during this period, you will need a passcode to unlock your iPhone.

After five unsuccessful attempts, you will need an access code.

Swipe at the bottom of the screen to switch apps

The newer iPhones have a lot of gestures to get around iOS, but typing the app switcher can be a little overwhelming. Here’s an easy way to switch between recently used apps. This is a feature that many people don’t take full advantage of, but when you add it to your swipe repertoire, you won’t want to come back again.

Learn all useful gestures

There are tons of other things you can do with a swift gesture, and we’ll cover them right here. Who knew there were so many different ways to wave your finger at the screen?

Setting up and using Apple Pay

Apple Pay continues to be an overlooked hero of the iPhone and the Apple ecosystem as a whole, and a lot has changed with the advent of Face ID. Without Touch ID authentication, you must pay attention to your iPhone before it allows you to pay. Sounds awkward, but it isn’t.

Tap the screen to wake up your phone

With the Home button removed, waking your iPhone is as easy as tapping the screen and watching it kick in. Phones have been doing this for years, but it’s great to be able to do it with the iPhone. There is some fancy touch detection to try and avoid accidental touches waking up the screen.

How to set up and use your iPhone X, iPhone XR, iPhone XS, or iPhone XS Max

So you have a shiny new iPhone, but it’s all different. Apple’s iPhone 2018, along with the iPhone X, is a huge departure from everything before, and we’ll tell you how to use them.

You don’t have to keep an eye on the iPhone over the past few years to see that Apple is making a difference. The iPhone X has ushered in a new wave of iPhone that’s without the Home button, and it’s changing the way the iPhone works in many ways, not just how you exit an app. Removing Touch ID and introducing Face ID is one of the biggest small changes the iPhone has seen, and it affects the way iOS works, from authenticating purchases to entering passwords. The loss of the Home button has been enormous and it profoundly changes the muscle memory you’ve built up over the years.

But boy, oh boy, you have to retrain some gestures for a small price to pay for what you get in return. We know what to learn, no matter how good the new iPhones are. That’s why we’ve put together a collection of the most useful guides we have, all aimed at helping you get the hang of your new phone. By the time you read everything here, you will be a ninja warrior on iPhone.

A little about Mi Band 6

This year, Xiaomi really pleased the fans of the iconic fitness bracelet: the company removed the button, maximized the screen and updated the hardware inside the Mi Band. The device turned out to be really very cool (I’ll tell you more about this in the review), so if you are just thinking about buying, I say from myself, it’s worth taking.

And if you have already bought Mi Band 6. we will tell you how to connect it to your smartphone and how to set up all the indicators.

Watch faces on Mi Band 6

Xiaomi said that there are a lot of interesting watch faces on the Mi Band 6. I can argue with this, because in fact all the dials are not very good at all, and for your own customization you are given only 5 options. And then, the maximum that you can do in them is just change the background image and the color of the text.

All other watch faces can be found in the “Store” section. But, I warn you, there are many anime, animated, some kind of childish options. But for a minimalist lover like me, it’s probably ideal to stay on the original dial. In the “Administrator” section, you can manage the displayed watch faces.

How to connect and configure Mi Band 6

Xiaomi has released a new product. Mi Band 6. We were one of the first to get hold of a new fitness bracelet. We will tell you how to connect and configure it.

How to connect Mi Band 6 to iPhone

I do not have a Global version. Direct from China, no NFC. So to speak, the first batch of brand new fitness bracelets. Nevertheless, there is already a built-in Russian language and after connecting Mi Band 6 to the iPhone, it is quite possible to use it and not worry about buying a global version.

To connect, you need either Android 6.0 or iOS 10.0. Fitness bracelet works via Bluetooth 5.0 connection.

  • Download the Mi Fit app (you can scan from the QR code in the instructions).
  • We go through registration. I didn’t have a new account, so I created it through my Apple ID. I also advise you. just a minute, quickly fill in the required fields and you can proceed to the connection.
  • We choose in the new menu “Bracelet”.
  • Then click on the link icon on the bracelet.
  • We are waiting for the devices to connect.
  • We confirm the connection.
  • Choosing which data we will track.
  • We confirm all permissions.
  • We are waiting for the bracelet to receive all the updates.
  • Immediately after syncing, your fitness tracker will be configured for the language your iPhone uses. Sorry, Ukrainian is not available.

How to connect Mi Band 6 to Android

The connection of the fitness bracelet to Android is the same as for the iPhone. You just need to download the Mi Fit app and go through all the steps: from registration to pairing the device, described above.

From face to numbers

The Siamese neural network is basically made up of two identical neural networks that also share all the weights. This architecture can learn to distinguish between distances between specific data such as images. The idea is that you transfer pairs of data through Siamese networks (or simply transfer data in two different steps through the same network), the network maps them in low-dimensional characteristics of space as an n-dimensional array, and then you train the network. to make a comparison such that point data from different classes was as far away as possible, while point data from the same class was as close as possible.

Ultimately, the network will learn to extract the most meaningful features from the data and compress them into an array, creating an image. To understand this, imagine how you would describe dog breeds with a small vector so that similar dogs would have almost similar vectors. You would probably use one number to encode the color of the dog, another to denote the size of the dog, the third for the length of the coat, and so on. So dogs that look alike will have similar vectors. A Siamese neural network can do it for you, just like an autoencoder does.

Using this technology, a large number of faces are needed to train such an architecture to recognize the most similar ones. With the right budget and processing power (like Apple does), more complex examples can also be used to make the network resilient to cases like twins, masks, etc.

What is the final advantage of this approach? The fact that you finally have a plug and play model that can recognize different users without any additional training, but simply calculate the location of the user’s face on the hidden face map formed after configuring FaceID. In addition, FaceID is able to adapt to changes in your appearance: both sudden (for example, glasses, hat, makeup) and “gradual” (growing hair). This is done by adding face reference vectors calculated from your new appearance to the map.

Understanding FaceID

“… The neural networks that FaceID is based on don’t just perform classification.”

The first step is to analyze how FaceID works on the iPhone X. The technical documentation can help us with this. With TouchID, the user had to first enroll their fingerprints by tapping the sensor several times. After 10-15 different touches, the smartphone completes the registration.

Likewise with FaceID: the user must register his face. The process is quite simple: the user just looks at the phone as he does on a daily basis, and then slowly turns his head in a circle, thereby registering the face in different positions. This completes the registration and the phone is ready to unlock. This incredibly fast registration procedure can tell a lot about the basic learning algorithms. For example, the neural networks on which FaceID technology is based don’t just perform classification.

Performing a classification for a neural network means being able to predict whether the face it “sees” at the moment is the face of the user. Thus, it has to use some training data to predict “true” or “false”, but unlike many other deep learning use cases, this approach will not work here.

First, the network must train from scratch using new data captured from the user’s face. It would take a lot of time, energy and a lot of data from different faces (not the face of the user) to have negative examples. In addition, this method will prevent Apple from training a more complex network “offline”, that is, in its laboratories, and then sending it already trained and ready to use on their phones. FaceID is believed to be based on a Siamese convolutional neural network that learns “offline” to render faces in a low-dimensional hidden space, shaped to maximize the difference between faces of different people using contrast loss. You get an architecture capable of doing a one-time learning like Keynote mentioned.

How FaceID Works in iPhone X: Python Algorithm

One of the coolest things about the iPhone X is the unlock method: FaceID. This article explains how this technology works.

The image of the user’s face is captured using an infrared camera, which is more resistant to changes in light and color of the environment. Using deep learning, the smartphone is able to recognize the user’s face in the smallest detail, thereby “recognizing” the owner every time he picks up his phone. Surprisingly, Apple has stated that this method is even safer than TouchID, with an error rate of 1: 1,000,000.

This article has explored the principle of an algorithm similar to FaceID using Keras. Also featured are some of the final designs created with Kinect.

Implementing FaceID with Keras

For all machine learning projects, the first thing we need is data. Creating your own dataset will take a lot of time and collaboration, so it can be tricky. There is a website with RGB-D faces dataset. It consists of a series of RGB-D photographs of people standing in different positions and making different facial expressions, as would be the case with the iPhone X. To see the final implementation, here is the GitHub link.

A convolutional network based on the SqueezeNet architecture is being created. The network accepts both RGBD images of pairs of faces and 4-channel images as input, and outputs the differences between the two attachments. The network learns with significant loss, which minimizes the difference between images of the same person and maximizes the difference between images of different faces.

After training, the network is able to convert faces into 128-dimensional arrays so that photos of the same person are grouped together. This means that in order to unlock the device, the neural network simply calculates the difference between the snapshot required at the time of unlocking with the images saved during the registration step. If the difference matches a certain value, the device will be unlocked.

The t-SNE algorithm is used. Each color corresponds to a person: as you can see, the network has learned to group these photos quite tightly. An interesting plot also occurs when using the PCA algorithm to reduce the dimension of the data.

Experiment

Now let’s try to see how this model works by simulating a normal FaceID loop. The first step is to register a person. Then we will unlock both on behalf of the user and from other people who should not unlock the device. As mentioned earlier, the distinction between the person who “sees” the phone and the person who is registered has a certain threshold.

Let’s start with registration. Let’s take a series of photographs of the same person from a dataset and simulate the registration phase. The device now calculates the attachments for each of these poses and stores them locally.

Let’s see what happens if the same user tries to unlock the device. Different poses and facial expressions of the same user achieve a low difference, on average around 0.30.

On the other hand, images from different people get an average difference of about 1.1.

Thus, a threshold value of about 0.4 should be sufficient to prevent strangers from unlocking the phone.

In this post, I showed you how to implement the FaceID unlocking mechanic test concept based on edge embedding and Siamese convolutional networks. I hope this information was helpful to you. You can find all relative Python code here.

How FaceID Works in iPhone X: Python Algorithm

One of the most talked about features of the iPhone X is the new unlocking method: FaceID. This article explains how this technology works.

Having created a bezel-less phone without TouchID, Apple had to develop a new method to unlock the device in a simple and fast way. While some competitors continued to use the fingerprint scanner, Apple decided to update and revolutionize the way you unlock your phone. Thanks to the advanced (and surprisingly small) front depth camera, the iPhone X has the ability to create a 3D map of the user’s face.

In addition, an image of the user’s face is captured using an infrared camera, which is more resistant to changes in the light and color of the environment. Using deep learning, the smartphone is able to recognize the user’s face in the smallest detail, thereby “recognizing” the owner every time he picks up his phone.
