I updated to iOS 13.4 recently and after the update i was not getting any cellular signal on my phone.
I tried factory resetting the phone since resetting network settings was not helping.
Now after my iPhone boots up it still cannot get a signal and i cannot activate my iPhone.
I have tried restoring my iPhone using iTunes on my Windows PC but it's still the same.

How to Update Carrier Settings
You can manually check for and install a carrier settings update with these steps: Make sure your device is connected to a Wi-Fi or cellular network. Tap Settings > General > About. If an update is available, you'll see an option to update your carrier settings.
Update your carrier settings on your iPhone or iPad - Apple Support
I cannot do that since my iPhone cannot go past the initial setup screen now.
Will someone please help?
