Re: sim swapping is incredibly easy to do
Not knowing what this was about, I did some quick research.
What I found is that, yes, this is a thing and yes, it can be real headache.
However, there are a few prerequisites :
1) sim-swapping targets "profitable victims", which means said victims have been identified among the many - not so obvious
2) "Laying the groundwork for a SIM swap scheme involves collecting as much information about the victim as possible. - sounds like work, even if clueless people also have money
3) living in a country where phone providers activate new sims via phone call
And that is the crux. If you live in a country where the phone provider will not do any such thing over the phone, and instead send the legitimate owner a new sim via mail to the legitimate address, then this whole scheme is dead before it started.
