In the title of the article are brought two problems distinct text messages. One is related to not receiving type messages SMS (SMS Messages) and another of not receiving type messages iMessage when they were shipped in time cd The receiving iPhone was locked.

Before we see why these issues arise and how they can be resolved, let's see what is the difference between iMessage and a text message SMS.
Pe iPhone si iPadboth Posts SMS and the iMessage can be sent and received through the application "Messages”Present by default on all iOS operating systems. Even if both types of messages arrive and are sent through the same application, the sending and delivery protocol is completely different.
Let's see a brief description of the two services: SMS si iMessage, to better understand the reasons why these messages are not always delivered if they were sent within a time frame The recipient's iPhone has been locked.

Text Messages – SMS vs. iMessages

Text messages SMS they are present on all mobile phones, from the oldest models to the top smartphones. This service of SMS appeared virtually before the mobile phones, being present since 1984 on receivers - transmission and classic telephones.
Nowadays, Posts SMS are shipped and received through the mobile operator with the help of a Message Center. Sending and sending messages SMS does not require internet connection.

iMessage is a service IM, Developed by Apple and released on the iPhone with iOS 5in October 2011. Service iMessage are functioning only via internet connection (Wi-Fi or 3G / 4G), and data transport is done through servers Apple, where each device will be registered. This service is only available on devices Apple: iPhone, iPad, iPod Touch and on all computers or laptops Mac/ MacBook pet products.
iMessage si SMS there are no compatible services. You cannot send a text message through the protocol iMessage on an ordinary smartphone or on an iPhone that does not have this service activated.

Activation and deactivation of the service iMessages is made of Settings →  iMessage (green check mark). Because the recording is through Message Center of Apple, upon activation of the service you will be charged with the equivalent shipping one SMS international. You will be charged if you use this service on 3G or 4G and you do not have the data traffic included in mobile internet subscription.

After we understood in general what are the differences between the two text message services, let's see now why the messages that were sent to us while we had our iPhone turned off are not coming in.

Why are we not receiving text messages? SMS which were sent to us while our iPhone was closed

The fact that SMS- files no longer enter the iPhone after it has been reopened, it is not a real problem. One of the features of text messages SMS, It is "Period of validity”(Validity Period). Depending on the mobile operator of the sender of the message, they can be sent with a limited or unlimited validity. There are mobile phones that offer this option in the settings. posts SMS depart from the sender's phone to Message Center of the mobile phone operator (on older phones, the Message Center number had to be set manually ca SMS to be able to function), so that they can be delivered to the recipient. If the sender has set as the shelf life is one hour, and we we open the iPhone after more than an hour from the moment the message was sentIt will be deleted from the Message Center of the operator and it will no longer be delivered.
This is the main reason why we no longer receive the messages SMS shipped during the period when the iPhone was closed.

Why don't we get the messages iMessage which were sent to us while our iPhone was closed

As I said above, the protocol for sending and receiving messages iMessage on the iPhone it is done through the Internet and through the servers Apple.
Failure to deliver messages iMessage can have several causes:

  1. The sender did not have an iPhone, Mac or iPad connected to the Internet at the time of sending the message, then closed the device or deleted the message from the Messages application.
  2. The sender did not have the "Send as" option set in the "Messages" application SMS” which allowed the message to be sent as SMS when the service iMessage not available.
  3. The recipient's iPhone is not connected to the Internet after it has been reopened, and the type messages iMessage I can not enter.
  4. The sender deleted the message or conversation before it was sent to the servers Apple or before the recipient opens their device.
  5. The problem of registering the mobile operator on the servers iMessage but by Apple

These are the main reasons why messages sent to you will not arrive after you reopen your iPhone.
If you have discovered other causes or we can help with something, do not hesitate to leave your comments.

I am happy to share my experiences in the field of computers, mobile phones and operating systems, to develop web projects and to bring the most useful tutorials and advice. I like to "play" on the iPhone, MacBook Pro, iPad, AirPort Extreme and on operating systems macOS, iOS, Android and Windows.
