For a long time, Apple didn't acknowledge this bug so there wasn't much to do to fix it, but that changed after Apple released a free tool to remove your phone number from iMessage that gets your texts moving again. The Cause of the Bug When two iPhone users are texting each other, by default their messages are sent via iMessage, Apple's free iPhone-to-iPhone messaging tool (you can know a text has been sent using iMessage because your word balloon in the Messages app is blue). When one person in a conversation has an iPhone and the other person has another kind of phone — Android, for instance — traditional text messaging is used (represented by the green word balloon). No problems so far. The problem comes in when someone who used to have an iPhone, and thus used iMessage, switches to Android or another platform. In that scenario, Apple's system sometimes fails to recognize that a switch has been made and it will still try to deliver the text via iMessage. Because the iMessage network is totally separate from the standard text messaging network, the message dead-ends and never gets delivered to its recipient. To make matters worse, the sender doesn't know that the message wasn't delivered, either. Need to delete any of those missing text messages? Deleting texts on the iPhone is easy. Fix the Bug With Apple's Free Tool Apple has released a free tool that lets former iPhone users unregister their phone numbers from iMessage, which prevents texts sent to them from falling prey to the bug. If you used to be an iPhone user, and have switched to Android and aren't getting some texts, do the following: Go to Apple's Deregister iMessage website. Scroll to the section titled No longer have your iPhone? Enter your phone number (this assumes that you carried your phone number from your iPhone to your new Android phone), and select Send Code. You will receive a text message on your new phone with a 6-digit confirmation code. Enter that code into the website, and press Submit. This removes your number from iMessage and solves the problem. Fix the iMessage Bug Before Switching to Android If you're planning to switch to Android, but haven't done so yet, there's an easier way to prevent the bug from happening: remove your number from iMessage now. This means that you won't be able to get free iMessages any longer, but all of those messages will still be delivered as text messages, so you won't miss anything. To do this: Tap the Settings app. Tap Messages. Move the iMessage slider to Off/white. Fix the Bug If You Still Have Your iPhone If you've already switched to Android, but haven't yet recycled or sold your used iPhone, there's another way to solve the bug. In that case: Take the SIM card from your new Android phone, and insert it into your iPhone. This temporarily moves your phone number back to the iPhone. Tap the Settings app. Tap Messages. Move the iMessage slider to Off/white. Put the SIM card back in your new phone. The Android bug isn't the only problem that you can run into sending texts.
