Thanks to an ongoing issue with the way Apple built its iMessage platform, users who switch away from an iPhone to an Android phone or any other cell phone are faced with a huge problem: once they bail on the iPhone, they often can’t receive text messages from contacts who are still using iPhones. This is because Apple’s system still sees them as iMessage users, and it tries to deliver messages sent using Apple’s Messages app as iMessages. To make matters even worse, the iPhone users who send those messages see their status as “delivered” even though they are not being received.
Thankfully, there are ways to avoid this annoying bug if you’re planning to make the switch from iOS to another platform.

If you've succumbed to the temptations of Android — or even Windows Phone or BlackBerry — there are some steps you need to take to make sure the iPhone friends you leave behind can still reach you. iMessage works by routing iPhone to iPhone messages through Apple's servers instead of sending them as actual text messages. Unfortunately, unless you tell it to stop doing this, iMessage has no way of knowing you've left, at least until it times out after a couple weeks, and that's beyond frustrating. Luckily, deactivating it is easy. Here's how!
How to deactivate iMessage and before switching from iPhone to Android Samsung, BlackBerry, or Windows Phone
Easy steps from your iPhone before starting to use your new smartphone:
1.Launch Settings from the Home screen of your iPhone.
2.Scroll down and tap on Messages.
3.At the top, turn iMessage to Off.
4.Now hop into the Messages app and send some messages to people you know have iPhones to make sure they can message you back. You want green messages bubbles for everything.
That's all there is to it. Once you've done this, iMessage should hopefully deactivate from Apple's servers and you shouldn't have any issues, nor should you have to go any further into this guide. As a side note, the sooner you do this, the better off you are. If you know you're going out to purchase an Android, BlackBerry, or Windows Phone in 3 days, do this process right now. That way you have turned off iMessage and it gives the servers a few days to actually process the request completely and boot you off.
