Hello! Since I have updated my iPhone to iOS 8.4 I have an annoying problem! Most of the time when I send a message, the person is not receiving it, just after a couple of mins or hours which is very, very annoying. This happends when somebody sends a message to me, I receive the message after a period of time!(or after I send a message to me, or to somebody, literally speaking, when I send a message to me or to somebody again, seems like "the network is activating" and I start receive the messages. What should I do? I deactivated and activated iMessage, done reset to network factory settings, restarted the phone, but nothing...Any idea?
