There may be an iOS issue

In general, checking thatyour iPhone is up to dateis a good idea of guaranteeing that most of your device’s apps and features are running smoothly. However, even having the latest version of iOS installed can sometimes produce bugs that may render certain services temporarily unusable. If you inexplicably lose the ability to send messages through the Messages app, this may be the case.

Although this type of mishap is mostly out of your control, there are a number of things you can attempt to see if you can fix the glitch on your end. You can force-quit the Messages app by slowly swiping up on your iPhone screen to see all your open apps, swiping left or right to get to Messages, and swiping up on the app to exit it. You can also restart your iPhone by long-pressing on the side button and the volume down button simultaneously until you can slide the power button slider to turn your device off. Once you turn the iPhone back on, you can try opening the Messages app again to see if the refresh fixed the problem.

There also may be other issues with the particular group message that may be out of your control. When you open the group chat and it says you left the conversation, the only way to rejoin it is if someone still in the conversation adds you back. Otherwise, the best way to resolve any group chat issues is to start a new one.

Furthermore, using SMS or MMS messaging to send media may be limited by your mobile phone provider’s file size constraints. You should be able to send full-size images and videos through the Messages app — again, messaging rates will apply — but they may take longer to go through. To send photos quicker, you can try lowering the image quality of the photos exchanged in the app:
