Low Data Mode message interference in ios 26.1 on iPhone 11

Why this “Low Data Mode” prompt appears

• iOS is detecting a secondary SIM / travel SIM (usually eSIM).
• Apple assumes travel or backup plans often have limited or expensive data, so it politely asks if you want to go easy on bandwidth.
• This prompt usually shows up when:

1. 1. You insert or activate a new SIM/eSIM
   2. You switch the cellular data line
   3. You’re roaming or using a travel plan

Remove the SIMs and re-insert the SIM that is currently being used by you.

I have just upgraded my iPhone 11 to iOS 26.1. I now get interruptions to whatever i am logged into with the message "Low Data Mode". No matter whether I turn it on or off or adjust the mobile settings, it keeps repeating. I have even turned off wi-fi, all to no avail. Is this a bug in iOS 26.1?

Report your issue to your cellular data provider.

It's not always the iOS update's fault!  Many things can cause phone problems.  If you tell people you think it's an iOS update, it might make it harder to fix or find a solution for the real issue.

Remember, the right question often leads to the solution!

Was/Is your device Jailbroken? If that's the situation, please be informed that attributing the issues to iOS updates may not be accurate.

iOS updates aim to enhance user experience, boost security, and fix bugs rather than disrupt core features. The majority of the issues after updates might stem from underlying, unmentioned factors. Updates won't typically alter personal data but may refine settings or features. Backup before major updates for safety. Review Apple's update details and backup advice for a smooth process.

Kindly consider checking your settings and addressing any device issues before attributing the issue to external factors. This could be a pure coincidence that the iOS update affected the iPhone functions.

Before initiating a standard iOS update, it's advisable to create a backup. Have you completed this step? If yes, proceed with the restoration from the backup.
