Hello, so i am a newbie in anonymouse stuff, could you please explain is there some tools to prevent record your calls to record and recognize your voice? Some recomend to not use a sim card but how so only Voip? And what if i need mobile data how can you manage that if you dont have simcard?
If your primary concern is ubiquitous recording of voice calls (i.e. calls that are made via the voice network) then you need a SIM that is a data-only plan (or at least to use the SIM for data only) and then all voice communication should be via a secure end-to-end encrypted platform.
Whether this is necessary or appropriate only you can decide - because only you know what threats you realistically face.
In the extreme, you could limit yourself to making calls via such a platform only when connected to the internet via something other than mobile data. This could make sense if you are also concerned about the tracking capability that is inherent in the mobile phone network. In this scenario, you would not need a SIM card. In fact you wouldn’t need the modem at all and you could in theory remove it from the phone (but at the least you would use the hardware kill switch to keep the modem powered off).
If i will not use a sim card how can i have internet connection… I do need connection but can it be private if i will use vpn or something like that?
I am picturing something that routes all traffic through the Tor network. Like, with similar functionality to Whonix, but more lightweight, if that’s possible? I will try to do something like this when I get my Librem 5. Maybe someone with more Linux/networking knowledge than me has already accomplished it? Could it be done with local proxy rules on the device?
If you ever, at any point, do anything to identify yourself you run the very real risk of deanonymising much, if not all, of your activity for that session, possibly all of your activity from that device.
This is why TAILS is a live environment that is effectively a new device every time it is used, and whonix is separated from the host so that anything requiring identitification be done through not whonix.
No. You cannot prevent the person you’re talking to nor the cellular network from recording your cellular calls.
Even with encrypted voip the person you’re talking to could record your call. There are many VOIP providers you would have to look into which one is best for you, if it comes with a phone number to talk to non-VOIP users those calls would not been encrypted nor would your user account be able to be anonymous in most situations.
If you need mobile data then you need a sim card to identify your device to the mobile carrier whom in most situations will want your actual identity for regulatory compliance.
A few things. Anonymity and privacy are separate things. In theory you can have a privacy with a cellular connection, however that also requires trusting the network operator is actually respecting your privacy as they claim. A VPN only shifts whom you trust your internet data with, you move it from the Internet Sevice Provider to the VPN provider but that doesn’t change that at some point some amount of data can be seen by a provider.
There is no quick and easy one size fits all solution for Privacy, Anonymity, and Security as each person’s needs and risks need to be weighed against Convenience and Functionality.
It depends somewhat on what you are trying to keep private.
The contents of the phone call? Never really guaranteed private on the voice phone network. Only ever making calls using a service layered over a data connection and using end-to-end encryption can give you this. (Even then, the client software has to be open source in order for this to be solid.)
The details about the phone call? (who called whom? when? for how long? where were you at the time?) Never really guaranteed private on the voice phone network. Difficult even with end-to-end encryption.
Thank you for your answers, and what for stands Purism sim card Encryptor?
