![]() Google cannot provide the necessary settings through the SIM card or "over the air". ![]() Understanding how secure the iPhone is from a possibly malicious SIM cards might, because then I might be able to just do the workaround. This is a tangent from my original question, because figuring out which of the tech companies is more to blame for the lack of a correct carrier bundle for Fi in iOS isn't going to make 5G work for me. But I am not interested in speculating on why Apple isn't including the correct carrier bundle for Fi in iOS, and if it is more Google's fault or Apple's, as we really don't know and one can imagine "strategic" reasons either of them might have decided to cause (or chose not to fix?) this problem. It seems those links have since been removed by a moderator. Details on the settings iOS specifices for different carriers, the actual bundle used by iOS when talking to Fi, and the specific settings that bundle incorrectly specifies so features like 5G do not work on Fi, are in the pages my original question linked to. It works on the other networks fine because Apple includes the correct carrier bundle for those carriers in iOS. Thanks in advance for any insight anyone has!Īpple controls the carrier bundles shipped with iOS. How much of a risk is this? Hence my wanting to know how much an iPhone could be compromised via the connection to the sim card.Ĭould SMS messages be read? Is data that is stored in applications, like my password manager, safe? This involves physically installing a small microprocessor around the sim card to alter the data sent between the sim card and the iPhone.īecause Heicards aren't made by a major manufacture, I'm not sure if I should trust they don't have any back doors or accidental security vulnerabilities. Users have figured out one can use a Heicard to change the carrier bundle used for Google Fi to one that has the correct settings to enable 5G. The context for this is that both Google Fi and iPhone 12 & 13 support 5G, but iOS ships with the wrong carrier bundle config settings for Google Fi to enable 5G. I think my question essentially reduces to asking the following: How much could an iPhone be compromised via the connection to the sim card?
