de0u If I were to purchase a phone from your company with an "anonymous" SIM in it, I could choose to assume that your company hadn't recorded which SIM card you shipped with my phone, but personally I wouldn't make such an assumption
We won't record anything, not even your name. If you assume we somehow investigate you before selling you a phone to then register you to a sim card/phone then you are wrong. We don't record any customer data.
de0u Meanwhile, though indeed there are lots of people selling "anonymous SIM cards" online, making all sorts of claims [that are not] accurate. This piece might be of interest: Anonymous SIM card scam, especially the "Anonymous SIM cards are really anonymous?" part.
The sim cards ARE anonymous, no name or ID is required to buy or use them. As for the claim in your link that
But when it comes to the law enforcement agencies that will want to find a prepaid ("anonymous") SIM card user's identity, the situation changes radically: no chance to hide your identity. Whether using the network operator or through lawful interception systems, finding the identity of any prepaid SIM user is a matter of a few days or even hours.
That is complete nonsense. "No chance to hide your Identity"?
Please explain how anyone (law enforcement for example) can find the identity of a user with a phone using anonymous sim and a VPN to communicate via the Signal app.
de0u A claim that your company can provide SIM cards that would shield "journalists under repressive governments" is an extraordinary claim that calls for extraordinary evidence.
That depends on many variables, both technical and behavioral. It also depends on the definition of "shields". But I don't think the claim is extraordinary.
If a user is:
Using a phone with the aforementioned features (anonymous sim, VPN, Signal, automatic "airplane mode" every time the screen is turned of, random Mac address for each connection,etc)
Not falling into a pattern of allways using the phone in the same place at the same time.
i think it does a great job of "shielding" users to a very high degree. Of course, if a governments/agency deems you so dangerous that they are willing to spend millions in technology and manpower, not any communication method in the world is ultimately safe.
