Re: Unable to send picture messages on my new iPhone 18 Pro
Wondering whether Apple support's article (link below) can help:
For iOS27: See how to: Share content in Messages on iPhone - Apple Support
Eg: says:
"Share content with others
- Go to the Messages app on your iPhone.
- In a conversation, do one of the following:
- Copy and paste an image or a link into the text field.
- Tap the plus sign icon, tap Photos to browse recent photos and videos, then tap to add.
- Tap a message attachment, tap
, then tap a contact or the green Messages icon- Tip: When you tap
, you can also copy, save, or print your attachment.
Add a message (optional), then tap the blue oval with up arrow icon.
From another app (like Podcasts, News, or Music), select the content you want to share, tap
, tap Share, then choose Messages"
