Your iPhone should send messages normally most of the time, but you can try easy fixes when it acts up.
Key facts
- The other two protocols are RCS and SMS, the green bubbles
- With this, your iPhone will automatically resend messages as SMS when iMessage or RCS fails
- Without MMS, you can't send photos or videos via regular text messages to Android users, unless they have RCS enabled
- The first workaround when you get a "Not Delivered" error in Messages is to tap the red exclamation point that appears next to your message
Summary
Sending messages to friends and family on an iPhone is usually pretty easy: open a chat in the Messages app, type it out and you're all set once you hit Send. If that important message you need to send right away ends up not getting delivered, don't give up yet. But first, it's worth noting that the iPhone's Messages app is more complex than it seems. The most popular is iMessage, which is the one with the blue bubbles. The first workaround when you get a "Not Delivered" error in Messages is to tap the red exclamation point that appears next to your message. Because iMessage (and RCS) relies on the internet, lacking a connection means your message won't be delivered.
