I'm glad there is such project, but we are far to have a solution as a whole.
Anything that I need to do, that is not a crime obviously, it requires a specific form of identification, I live in UK and it's impossible to get it done, let me explain.
Email
I need to use certain communication systems, let's start with the email, but all the emails are blocked if you use Tor or VPN, or some email providers don't send emails to specific email providers.
Oh, I also need gmail if I want to use the Accrescent store and install the Gapps, which is the only safe method provided by GrapheneOS, I know it's not your fault, but that's how it is.
Telegram
If I use Telegram, I need a mobile number, it couldn't be more complicated than this.
A mobile number requires identification, so they will know who you are and where you are all the time, so what's the point in using GrapheneOS or any other similar solution?
I found a method with a Paysafecard and similar, but I'm pretty sure that those cards are blocked pretty much everywhere, so, how can I deal with my needs?
Without identification, aka registration, Paysafecard allows 40 pounds in UK, just to give an example.
I could buy several of them (assuming they are not blocked), but the SIM provider could easily block my account for the many cards used...
It would be great if there was a SIM provider that doesn't require a card to pay your bill...
