Hey guys, I have a Google Pixel 8a Smartphone. It is a Degoogled Pixel 8a, currently with Calyxos. Is this the best custom ROM for privacy + security?

I also need to try to make it an Hardened phone. Not a Spy phone…not a Surveillance phone. Basically trying to make it an safe phone, anonymity phone.

What VPN could I use for this phone, and is there any other guides or settings guides you can recommend me.for my phone?

The sim card is a kyc one but im stuck with it.

Thank you.
