It's the mobile operators' fault for allowing the SIM transfers. It's relatively easy to social engineer one's way around a customer support agent over the phone if some credentials of the victim are known and, after gaining access to the phone number, the intruder can go to town resetting all victim's accounts. SIM transferring should only be allowed by visiting the company's offices and doing it in person after verification of the identity of the SIM owner. I have heard a lot of horror stories about SIM hijacking - mainly famous influencers' Twitter accounts getting hacked via social engineering and lax security protocols of the mobile operators.
I don't believe that you should blame anyone for what happen even the mobile operators are not aware but still
they are liable for what happened. Criminals will do whatever they think they can give them huge money. Every system has its vulnerability and its to us (users and the mobile operators) to make strengthen the security what we have by communicating each other regarding this matter.
You realize that you're contradicting yourself in just one line?
I'm willing to bet you actually have no clue what this is about.
It's hard to believe that you can lose so much if you lose your phone. A thief can use that phone to access your information and take out massive loans in your name. Or they could get your bitcoin keys, bank password, anything you use to keep money. People need to be more careful about what they leave lying around inside their phones.
But yeah, it's definitely the operators' fault. That's just plain stupid, transferring SIMs that easily.
Just stealing your phones means nothing, the thief would have first to get it unlocked, then try to find if you have accounts with 2fpa, find the username....It's plenty of time to just call your operator, tell them your security code and block the sim.
I'm glad I live in a country ,where phone numbers can't be just transferred from one SIM card to another.
What country is that?
