Sim Issue

Hi, I have an issue with this that isn't present on the previous rom I used (MagiskDefex) (Oreo). The issue that I have is that no features that use the Sim card seem to work, I basically now have a very small android tablet.

Incoming & Outgoing Calls, Texts and Data all do not work. Error is "Not Registered on Network".

Can someone please suggest a solution? I noticed that the last person who reported a similar (or the same) issue did receive a reply so maybe this is an uncommon problem?

My mobile network is PlusNet (UK)

Info: I am using the Android 8 bootloader, this phone was never once updated from stock, I actually only flashed it for the first time today and the Oreo custom rom I used worked perfectly.

Thank you.

UPDATE: * * * * *

I actually have quite a lot of problems with this rom, it could be issues with the stock rom itself and not anything you have caused but basically this is what's happened:

1) I got the calls/data and texts working through process of dalvik/data/cache wiping & reflashing the rom and magisk / pulling out the sim several times.

2) The phone has actually stopped data, calls and texts working again out of the blue and I don't know why.

3) Apps close themselves and crash all the time. I've only used this for about 20 hours and so many crashes have happened on Chrome and YoutubeVanced.

4) Chrome crashes when on facebook.com when pasting copied data, this happens 100% of the time and is consistently replicable.

5) Once or twice the phone booted to TWRP instead of Android itself, not sure why.

6) Youtube & Video performance is slightly choppy and not as stable as Android 8.0 Stock - having seen this occur on many custom roms on a variety of devices, I do suspect this does have something to do with the custom rom itself.

7) Oddly poor signal strength when network was working. I was getting 2 bars in my apartment (where I would normally get 4), same went for many areas outside where coverage was generally full strength. As a rule, it was about 50% of what I would expect.

NOTE: I am an experienced Android/Computer user with a lot of history in rooting devices and I assure you that your instructions for flashing this rom were followed to the letter.

I am going to to restore my phone from the backup and use rooted stock 8.0 again then perhaps try out one of the other custom roms for this site. That said, I really like this rom for how debloated it is and overall it seems like the perfect rom for this phone if the carrier bug can be ironed out.

Further Note: The initial flashing and further flashings of this rom took only ten minutes, not the projected 20, I do wonder if this perhaps means that some step in the flashing process was not working properly, but as it is replicable I can only assume that this is an issue with the rom, not my device nor twrp.

Second Update:

Restoring the backup through TWRP resulted in a bootloop which was resolved by data format. I have then reflashed NoVerity and RMM, then flashed PA6 Rom, then reflashed RMM. Following this, have followed setup procedure, restarted the phone, then installed Magisk Manager 7.1.2 (which correlates to release date for 19.1, which is included in the rom), then updated Magisk through the manager. The phone is now operating correctly, data, calls and texts, work as expected. This may be temporary as it has taken a lot of troubleshooting to resolve this, I will post an update in a few days to confirm if stability has remained or sooner if it has not. It is probably worth noting that IMEI remained intact throughout this whole process and was never once invalidated.

For anyone thinking of flashing this rom, my advice would now be to format data, install no verity & rmm, flash rom, then flash rmm once more.
