If that's the case, check out how to fix 'iMessage Not Delivered' problems on your iPhone. If iMessage is working on your iPhone but your messages aren't delivering, this is another subject entirely. You might find that you can use iMessage on your iPad, but not on your iPhone, so you know to focus your efforts on the iPhone. In this case, if you have multiple devices using iMessage, try sending messages with each of them. This feature is called Text Message Forwarding and has been available since iOS 8.1 and OS X Yosemite. You may not have multiple contacts you can check with if most of your friends use Android. Dont worry, Macs and iPads can now SMS text messages. On the other hand, if iMessage isn't working with any of your contacts, and you know they're using iMessage, the problem is probably with your device. If you're having trouble with iMessage when sending messages to a single contact, the problem is probably on their end. Are you sure iMessage isn't working with everyone, or is it just not working when you message one contact? Try sending iMessages to a few different people who you know use iMessage to find out if it works for any of them.
