I’ve been interested in switching over to a phone that isn’t a gold mine of my data for random companies etc. I’ve seen stuff for calyx, fair phone, graphene, and Linux phones. I’m curious as to how I would go about switching over. As of right now I use Android and mostly message through signal unless it’s for work and I’m unfortunately on Verizon. Which privacy first smartphones would people recommend for US users and how does it work putting it on a network? Do they go on the regular networks like at&t, sprint, Verizon etc? Or do they have their own or privacy first networks? Sorry if these are dumb questions I’m just interested in switching and figured this would be a good place to find info.
Alternative OSes for phones use the same carriers as everyone else. You can choose to use your phone on wifi only, without a carrier, to avoid using a carrier. You can also choose to use a VPN to make your data inaccessible to the carrier (although they’d be able to tell what cell towers you connect to).
In order to switch over, check the compatibility information for each of the OSes you’re looking at. If you don’t have a compatible phone, you’ll need to get one. Then you follow the install instructions for the chosen OS. GrapheneOS was very easy to install for me – I switched to it when my old phone broke.
