Since this year, I have two phones:

1) An iPhone Se 2022 that I use for TOTP, banking and auth. It is always in airplane mode, unless I need to login to banks (etc). The OS will receive security updates till 2032.

2) A Pixel phone with GrapheneOS for daily use: Internet browsing, routing, phone, message etc.

I found this is the only usable way in 2025.
