So is this technically possible? Basically can the service provider somehow hack into my phone and use the microphone to hear the surrounding of my phone if they somehow have a backdoor/malicious code on the sim card they gave me?
And if this is even possible to do with a SIM card, does iPhone have a protection against such an attack? (malicious service provider/SIM card)
I know this is not something that service providers in countries like U.S would do(probably), but in a country like China I would assume there might be a slight chance of this happening, so I was wondering if its possible or not and does iPhone protect against it?
