Not sure what the point of the service is. Given that it's more expensive than other MVNOs, and isn't even more private. You can still buy prepaid SIMs in store with cash, so it's harder to get more private than that. Not to mention this company asks for your zip+4 code (which identifies down to a specific street), and information for E-911. It's basically like Trump Mobile but for people who care about "privacy".
I was unaware that you could buy a SIM with cash and no private data collected. I thought they had KYC laws like prepaid cash cards.
Clearly there is no point in it for you. The stores would ID you. As for the nine digit zip, I don't think they validate it. Your anti-privacy agenda is crystal clear.
Can prepaid eSIMs be used anonymously?
