I upgraded my iPhone from iOS 17.2.1 to iOS 17.3, and noticed that my cell signal has disappeared. It shows "No Service".
I have reset the network settings, I have toggled airplane mode on and off, I have restarted the phone a couple times as well, but it is not working.
Anyone experiencing the same issue? Or is there a way I can downgrade my phone back to iOS 17.2.1
iOS updates generally aim to enhance user experience, boost security, and fix bugs rather than disrupt core features. No service 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.
This seems purely coincidental so please check the Setting on your device.
