When users coming to OS X first log into the system, one of the things that gets activated when they activate their iCloud account is the iMessage app. Well, if the user activated iMessage on an iPhone anyway, on the computer it was going to come out that he could be contacted through the number or through the email addresses that he had registered.
However, if for whatever reason, the user stopped using an iPhone, the number would continue to be registered on Apple's servers, This being a problem for the apple servers bitten by the messages that would be redeemed to them without the user already using the system.
To solve this problem, those in Cupertino, after almost more than a year since they announced that they were going to find a solution, launched a website to unsubscribe iMessageIt is to go, an online tool that will serve for those users who no longer have an Apple device, that is, an iPhone. If the user still has the iPhone, just go to Settings> Messages and disable iMessage.
Otherwise, the online tool that Apple has launched under the name of Unregister iMessage. In this way, users who have stopped using an iPhone will receive text messages that until now were redirected to the iMessage service at Apple.
Regarding the online service, the steps that must be followed to generate a code that will be sent to the phone number that is no longer an iPhone is explained in a very detailed way so that, after receiving it, it is entered on the web and so I can unsubscribe that iMessage number.
You have to know that if a user has gone through the process of canceling the device's iCloud account and restored content and settings on the iPhone with their SIM card inside it, the iMessage service was successfully canceled. The problem comes when the user takes out the SIM directly and enter it in another non-iOS terminal leaving the service activated on the iPhone that you leave.
