Apple has recently updated its support documentation to address a prevalent issue affecting iMessage users on iOS 26. Users have reported encountering Not Delivered alerts, messages appearing as green SMS/RCS bubbles instead of the usual blue iMessage bubbles, and messages being sent from their email addresses rather than their phone numbers.
Root Cause of the Issue
The primary cause identified is the incomplete activation of the eSIM during the initial setup of a new iPhone running iOS 26. If users opt to set up their eSIM at a later time via the Settings app, iMessage does not activate automatically, leading to the aforementioned issues.
Steps to Resolve the Issue
To rectify this problem, Apple recommends the following steps:
1. Open the Settings app on your iPhone.
2. Scroll down and tap on Apps.
3. Select Messages.
4. Toggle iMessage off and then back on.
This manual activation ensures that iMessage functions correctly after setting up the eSIM post-initial setup.
Additional Context
This issue predominantly affects users who bypass the eSIM setup during the initial configuration of their new iPhone. It may also impact individuals who switch carriers and set up a new eSIM through the Settings app.
This is not the first iMessage-related glitch observed since the release of iOS 26. Earlier this month, Apple provided guidance for users unable to activate iMessage with their phone numbers, highlighting the importance of thorough setup processes to ensure seamless functionality.
User Experiences and Feedback
Many users have expressed frustration over these issues, especially those who rely heavily on iMessage for daily communication. The appearance of green bubbles, typically associated with SMS messages, has led to confusion and concerns about message delivery reliability.
Apple’s proactive approach in updating support documents and providing clear instructions demonstrates its commitment to addressing user concerns promptly.
Preventive Measures for Future Setups
To avoid encountering similar issues in the future, users are advised to:
– Complete eSIM Setup During Initial Configuration: Ensure that the eSIM is fully set up when first configuring your new iPhone.
– Verify iMessage Activation: After any changes to your SIM or eSIM settings, check that iMessage is activated by navigating to Settings > Apps > Messages.
– Regularly Update iOS: Keep your device updated to the latest iOS version to benefit from fixes and improvements.
Conclusion
While the Not Delivered iMessage issue has caused inconvenience for many users, the solution provided by Apple is straightforward and effective. By following the outlined steps, users can restore normal iMessage functionality and continue to enjoy seamless communication on their iOS devices.
