Is it safe to chat with iMessage on iPhone?

Port-to-port encryption doesn't mean that your iMessage is secure enough to hide your whereabouts. Because Apple stores a lot of iMessage messages that can reveal your contacts and location, and even share them through court enforcement orders.

According to a newly obtained document of The Intercept, Apple records the number you enter and the message conversations on your iPhone, along with the date and time you enter those numbers and your IP address, which can be used to identify your location.

In fact, every time a user enters a ** number for a message conversation, their iPhone iMessage will contact Apple's servers, and the system will give the iMessage message.

Apple records every phone you query and sees who's in the iMessage system and who's not," the interception report said.

In addition, the company was forced to hand over the information to comply with an effective court enforcement order – it was easy to "register" or "mine and track the device."

iMessage is secure.

Apple's approach to privacy settings has been doing a great job, and Apple's developers use end-to-end encryption to protect iMessage and FaceTime conversations on all of users' devices. Apple's researchers designed iMessage and FaceTime so that when a user's data is transferred between devices, no one else can decrypt the user's data.

With regard to privacy information, Apple users can choose to automatically delete Apple's researchers' messages from their devices after 30 days or a year, or to keep them permanently on their devices. End-to-end encryption provides the highest level of data security, and the user's data is protected by a single key. The key comes from a message unique to the user's device and is combined with a device passcode that only the user knows, and no one else can access or read the data.

Introduction to iMessage

iMessage is an instant messaging software launched by Apple, which can send text messages, **, etc., with good security. Different from the operator's SMS and MMS services, users only need to support data and broadband data through WiFi or cellular data networks to complete communication.

On March 10, 2020, according to Macrumors, Apple is testing new features for iMessage internally, including mentioning "@" and retracting messages, which may be released as soon as iOS 14.

The SMS displayed in green belongs to the traditional carrier SMS, that is, it is generally charged according to the number of SMS. There is no limit to the sending of this kind of text message, and it can be used regardless of the phone model.

As shown in the figure below, the background color of the SMS sent by you is shown in green, indicating that the SMS of the traditional carrier, that is, China Mobile, China Telecom, and China Unicom, is currently used. In addition, you can also see a prompt with the words "SMS MMS" in the text input box.

The next thing to highlight is the text message with the background color shown in blue, as shown in the image below. In fact, this is a service that Apple provides for its own devices to send messages for free over the Internet, that is, iMessage, whether using a wireless network or a mobile network.

Of course, if you want to send a message with a blue background, you need to have certain conditions. First of all, you must be using an Apple iPhone and have turned on the iMessage function service in [Settings - Messages]. As you can see in the image below, as long as you're using an iPhone, you can turn on this feature yourself.

In addition, the other party also uses an iPhone, and when the iMessage service is turned on, they can send free messages to each other. It's worth mentioning that you can send free iMessage blue messages not only between iPhones, but also between iPod touch, iPad, and Mac, as long as both of you have iMessage turned on.

There are also some tips when using iMessage, when you encounter a network signal from time to time, the message will not be sent. Therefore, in the setting interface of iMessage, that is, in [Settings - Messages], you can turn on the [Send as SMS] option, so that when the network is not smooth, the system will automatically switch from iMessage to traditional SMS without delaying the sending of messages.

In addition, when sending an iMessage, you can also switch it by long-pressing the message being sent and selecting the Send with SMS option.

1. Because the network signal is not very good, the network is delayed! After using the mobile phone, after exiting the interface, enter again, and it shows that it has actually been sent out in the sending. In general, in this case, press the sensor button on the right side of home. Re-entry is on it!

At the same time, check whether the text message on the phone can be sent, whether the airplane mode is turned on, etc., just turn it on again!

2. Caused by the use of mobile phone management software, there is a boot prohibition item in the general mobile phone management software, after entering this software, check whether the text message is also banned, if it is banned, change it and restart the phone.

If it still can't be solved, you can try to restore the factory settings, but remember to use backup software to back up the information on your phone!

3. Turn off the mobile SMS function, this situation as long as you call **, it is possible to solve it with a manual service!
