Is anyone with more knowledge than me able to comment on the privacy claims Purism are making with their (USA only) SIM?
Major cellular providers are creating unified customer identifiers based on customer account information (name, address, billing information) and unique identifiers on your mobile devices so they can “identify users across multiple devices and serve them relevant advertising.
Librem AweSIM adds an extra layer of privacy to your customer data to protect you from targeted tracking. We register your phone number in our name on your behalf and keep your personal and financial data private and out of the hands of companies who would sell it to others.
