Many! I think the biggest bang for buck in terms of small learning curve and ease of transition for most people is moving to GrapheneOS on mobile.

Otherwise, what type of data are looking to secure?

Great, I’m using graphene! One thing I’ve been trying to figure out is a good voip solution for all legacy calls/texts. Haven’t been able to find a good solution that gets 2fa from banks (who some still force a text) and that works well behind a vpn. Ideally I’d also be able to get incoming call/message notifications without installing google play services on my phone.

Main reasons I’d like to do this is I figure that reduces the chances of being sim swapped (no one uses/knows my actual sim number) and if my VoIP numbers get caught up in mass surveillance, it isn’t tied to my location (via SIM card cell towers)

isnt this what silent.link esims are for?

It gets you a data only, non-kyc sim, but that isn’t my primary issue (I can easily grab a mint mobile sim from Best Buy with cash).

My real issue is finding the voip service that can reliably receive legacy calls/texts (even when behind a vpn), can receive 2fa codes, and can notify me of incoming calls/sms without google play services tarnishing my graphene device.

That's a tough one. You'll find that many 2FA systems for cell numbers don't work for voip numbers. Banks, for example, will check your voip number against a list of possible cellular numvers and when it's not on the list, they won't accept it.

The best setup I've found though for setting up voip on Graphene with notifications, calls, texts, etc comes from Michael Bazzell. inteltechniques.com

Awesome, thanks. Will check out Bazells recommendations to do this!

It's in his Mobile Privacy ebook

Thanks, yeah I found it last night, great recommendation!

TLDR for those that may be seeking a similar solution, he recommends either using mysudo or using an app called Sipnetic paired with a twilio voip account.

I’m going to test these out as I’m not sure how they’ll perform behind a vpn.

In terms of handling sms 2fa (when you have no choice, like some banks), he gave an example of a client of his putting a second SIM/esim on the phone that is $5/month for call/text and leaving it disabled whenever you aren’t expecting a 2fa code.
