If you are asking this question now, it means your iMessage application does not display a delivered check mark even after your messages are pushed. This calls for concern if a 'Not delivered' symbol is not shown either and that space is just left blank. If you've been having this issue, you shouldn't panic because many people have also had this issue, and there are solutions available. It is something that can be fixed easily. There are two trustworthy methods we recommend and both of them work even your device runs iOS 12.
1. Make Sure Your iPhone Is Optimized to Send iMessages
There might be a few things that you overlooked when setting up your iMessage. To confirm that everything is selected properly, backtrack and check all the settings on your phone related to iMessage. Here are a few things you should check for:
1. Check internet connection
Make sure you are properly connected to the Wi-Fi or your cellular connection. You may just go to Settings > Wi-Fi to check if your Wi-Fi is properly connected. Check if the Cellular Data is turned on or not in settings too.
2. Check cellular data balance
You might be out of cellular data and not even know it. Go to Settings > Cellular > Usage and see if your data has run out.
3. Check contact list
Check if you're sending to a contact with just an email ID or a number. It might help if the contact is saved along with the email ID of the person. This shouldn't be a hassle as everyone who uses iMessage already has an Apple email ID.
4. Check if you're signed into iMessage correctly
To be totally sure of this, it is advisable you sign out of iMesssage and sign back in. To do this, go to Settings and then Messages. Tap on the 'Send and Receive' option. Next, tap where it says 'Apple ID: (your Apple ID)' and select 'Sign Out'. Sign back in using your Apple ID and test to see if it worked.
But if all the above have been checked, but the problem still remains unsolved, it could mean that the recipient's phone cannot receive messages at the moment. It could be switched off, put in Airplane mode or out of range. This means that the message has already been pushed and will deliver once they have a good internet connection. The message can also be delivered after a few minutes as a text message, if you selected the option of delivering as text when iMessage isn't working. This option is labeled 'Send as SMS'.
To enable Send as SMS, go to Settings and select Messages to view the options. This will help in the event that iMessage fails, and your messages will still get delivered as SMS.
