iPhone 14 pro no sim card installed error after iOS 26 update

Hi! First time poster here and after battling with iOS 26 update twice on my iphone 14 pro I got the no sim card installed error. After finishing with the updates and reset the network and cellular data on factory settings, I could not get the sim to work (I tried sim from 2 carriers to no avail). Finally I recovered my device to 18.6.2 and to a previous icloud backup and all the settings were back to normal. Have you experienced anything like this specifically on iphone 14 pro after updating?

iPhone 14 Pro, iOS 18

Correct with an easy method. After you have downloaded itunes, you visit (https://ipsw.me/) and choose the device and the firmware that corresponds to your device, you download the correct file (for example in my case it's this:)

pay attention to the green tick - it means that the sw is signed which makes it recognizable from itunes. (there are other sw versions with red X marks). Then once inside itunes, press shift + restore button and choose the file you have downloaded and begin.

Before all of this, make sure to have a solid backup on icloud as well as the find my option turned off. Hope that helps!

Yo actualice mi iPhone 11 Pro Max a iOS 26, la tarjeta SIM no funciona en absoluto, no me permite realizar la activación por lo que tendré que volver a iOS 18

Are you experiencing the same issue? Check if my answer helps or I recommend to try backing your data up, resetting some functionalities (network/cellular) and re-check the update state.

No hablo español. Yes, better revert to ios 18. Something weird is happening with the the sim card read then across the devices.
