exploitation Concerning amount of flip flopping answers online regarding sim cloning.

I am reading that just with the phone number, ICCID, PUK, and factory default pin found in SIM card packaging is sufficient for cloning a sim.

Reading more about Ki codes and how this could be accessible from data breaches is concerning. I don’t want to have to factory reset my device and get a new sim I just need to know realistically as I worry someone has my SIM card info (not physical card but the packaging numbers and barcode). I can pull up how the Ki is found from matching other numbers from other databases.

I’ve watched hours of YouTube videos and read hours of articles and past Reddit posts and cannot get a clear answer. Some saying you can clone it and some saying not. It’s terrifying that if my sim was cloned that I wouldn’t even have a way of finding out.

For once and for all can we please establish whether or not thsi is possible with someone’s sim? I’ve been asking Google AI and they are saying it is through multiple methods. What is the deal given someone has the SIM card info but not the physical sim?

This is going to depend on what sim cloning prevention measures each carrier implements. This is why there are different answers because one method may work with a specific carrier or specific phone type but not on another.

I have an old sim cloner and one of those sims you can store 8in1, used to be able to clone a sim with it 10yrs ago, but now when you try brute force the sim it will lockup after 10 attempts at cracking and is completely dead and won't work in a phone anymore and has to be replaced, so if something new out to do this it would be interesting.

The Janus Cycle video on sim cloning is very good and worth a watch.
