If it is sent it means the text is delivered to the base station but there is no receipt come back.
What does text message not delivered mean. You should see every device you have registered to your Apple ID. If the iMessage never shows a Delivered or Read message and its still blue then you may have been blocked but not always. This might mean the number is invalid or out of use or it might mean the phone was inactive eg.
They are dozens of reasons why messages may not be delivered or may be delayed. These are network-standard statuses that are returned by SMS providers. When the text says deliverd it just means that it was sent out if the phone you sent it to actually recieved the text your end will say recieved rather than delivered.
If the message was not delivered it may show as Pending or None status. Check the tab for whichever ones you want to use. This message is for the sake of the information of an individual that your information or whatever is still in your own pocket.
More detail on this here. As mentioned above the appearance of the Delivered message is not an indication that the recipient has seen the message or is aware that it has arrived. The statuses will show Received Delivered or may simply show the time of delivery.
This can be due to a full inbox or device memory issues so clearing the cache and restarting the device can do the trick. What Does It Mean When iMessage Doesnt Say Delivered The simple meaning of iMessage doesnt say Delivered is that the iMessage has not yet been delivered to the person whom you are sending due to. It does NOT mean the recipient has opened it merely.
In these cases you dont need to rush into anything as your iMessages will remain pending until they actually can be delivered. If their SMS receiving capability turned off SMS messages cannot be delivered properly to the phone number. Have you ever sent a text message only to have it not be delivered.
