iOS 26 Cellular doesn't work after update

Hello,

I updated my iPhone 14 Pro to iOS 26 today, and I've noticed that cellular service is not working at all.

When the phone booted after the update, it didn't ask for the SIM PIN code.

I also went to Settings > Mobile Service > SIM PIN and tried to disable the PIN, but when I tried to tap on Change PIN, nothing happens.

Additionaly, my phone number no longer appears in the mobile service section.

Also, when I open SIM Applications, I can see my carriers services listed, but when I tap on them, nothing happens.

I have already tried:

- Restarting the device

- Reinserting the SIM card

- Checking for carrier settings updates

Is anyone else experiencing this? Any solutions?

Apple just pushed out an update to iOS 26 which addresses the issue of eSIM card fail caused by iOS 26. I updated to 26.0.1, restarted my phone and now I have cell signal again. Don't know how long it will last and I put at least 20 man-hours into fixing it. 3 trips to T-Mobile, 3 trips to Apple store and long conversations w/ T-Mobile tech support who said they were aware of the issue and reported it to Apple. So Apple addressed the issue with the 26.0.1 update. Fingers crossed!!

“I updated to the latest iOS 26.1 version without any issues. Before starting the update, you just need to remove the SIM card. After the update is complete, insert the SIM again. I followed this process and faced no problems.” Iphone 14 Pro ( Dual sim )

Following my earlier post requiring assistance with failure of the cellular module on my iPhone 15 immediately after IOS 26.1 update.

Having tried the majority of recommended solutions found on this forum, I took my 19month old phone to my local Apple store. I was expecting bad news and clinging to a hope that there may be some value in trading up to the latest model.

Having explained the issues to staff, I was informed that, because I purchased my phone directly from Apple, I had a 2 year warranty on the cellular components and the repair was going to be without charge to me.

Repair done and phone now fully restored and working perfectly!

I’m very grateful to Apple but still puzzled as to why there’s nothing official online about this issue.

I had the exact same problems, did everything people recommended, nothing worked…until I flipped the sim to the other side of the tray and problem solved! I’ve got an iPhone 14

The SIM flipping solution works. iPhone 14 here. My tray only had space for one SIM, so I bought a generic one for dual SIM and problem "solved," phone working normally. Calls, data, everything.
