Also, do you mean to say that only the employee of the telecom can do this sim hijacking or anyone with the required expertise can perform this evil act?
Never heard of such sim Hijacking I think telecom can able to read your messages but only selected staff can able to do it I guess.
There is another risky one if you already brought your phone to any phone tech there is a way to make a clone copy of the phone number only if you have the sim physically by using a sim reader you can make a clone copy of that sim.
So it is very risky if you bring your phone to any repair shop and you forgot to remove the sim card or someone near you that knows how to clone your sim card. That's very risky both of you received the same messages.
Ok I can now understand the risk involved in using SMS as a 2fa for trading platforms but do you think that authenticators like google authenticator can't be cloned if you send your phone to a repair shop etc ? Even if you give your phone in your friend's hand for 1 or 2 mins and he can easily export all your accounts using QR code. So how secure is the authenticator in this case
