If you’re having trouble getting your messages through, there are a few things you can do to check. First, make sure that your iPhone is connected to a strong Wi-Fi signal. If you’re using an iPhone 5 or later, make sure that your phone is updated to the latest operating system. Next, try restarting your iPhone. Sometimes problems with the network can cause messages to be blocked. If all of those things fail, you can try using a different phone or email account to send and receive messages. ..
