To the OP and all those affected…

Contact your Carrier:

Give your carrier, and see if they’ve had any complaints about this. Report back what they have to say in this. It may come down to getting a new SIM card or eSIM card for your device.

Report this to Apple:

Do your Part: Provide Apple with feedback on this, letting them know about this issue.  Apple may not get back to you directly, but the more feedback they receive on this, the more they will know what is occurring, and what bug fixes to include in updates to come. Apple will know nothing of this, if you don't report it to them.

1. Go Here: Feedback - iPhone - Apple
2. Select: "Bug Report" for the "Feedback Type"
3. Comment: that this all began after installing an update. Include the URL of this thread.
4. Proceed from there as necessary

Yes, thankfully. Swapping the sim around in the tray worked for me. I think though with the iOS 26.1 release the issue has been ‘quietly’ fixed by Apple...

"Same issue here. I don’t have any mobile data on my phone after updating to iOS 26. Any solution for this ?"

Wait it Out.

By words of the OP: Update, it’s finally activated. Guess it just took a bit.

I called Apple tech support about iMessage not working with iOS 26 on iPhone 14 Pro Max. They said it would be fixed in a couple of days, not fixed yet. This upgrade is so buggy, I wish they hadn't released it till it was actually workable.

Same issue here. I don’t have any mobile data on my phone after updating to iOS 26. Any solution for this ?

I too have an expensive paperweight now… can’t make phone calls, text or get online. ‘Fixes’ have no affect.

I have updated and did a lot of things, but nothing works, somebody knows a solution?

Still having this issue?

I went to T-Mobile to have them reinstall my eSIM. It didn’t fix the problem.

I don’t have any mobile data on my 14 pro and the signal bar is full and I can’t make phone calls after updating to iOS 26

Did you ever solve this problem?

That’s good. Ya probably was a bug that the update fixed.
