pixpot Despite the lack of direct identification, mobile network operators still allow anonymous prepaid SIM cards to access the internet and communicate over cellular networks. The network identifies the SIM card based on its unique International Mobile Subscriber Identity (IMSI) and the authentication keys stored on the SIM card. The IMSI is not directly tied to the user's identity during the purchase process, making it more challenging to trace back to an individual.
An earlier claim was "not registered to any person or company", which is quite different from "not directly tied to the user's identity" / "more challenging to trace back to an individual".
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.
Meanwhile, though indeed there are lots of people selling "anonymous SIM cards" online, making all sorts of claims (including "GPS spoofing", LOL), that doesn't make those claims accurate. This piece might be of interest: Anonymous SIM card scam, especially the "Anonymous SIM cards are really anonymous?" part.
At some point if your company does ship "anonymous SIM cards" to your customers, the customers (and anybody publishing a review of the product) will discover who issued the SIM cards, and be able to evaluate claims like "anonymous", "not registered to any person or company", "more challenging to trace back to an individual", etc. But 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.
