I just have one question about this sim port attack. In order for anyone to hijack my SIM, he needs to be present in my local area and it can't be done outside the country. Is it so?
For example, In my country, we have JAZZ, WARID, and Ufone mobile operators and since these networks are available locally, it is not possible for anyone to port my sim internationally and get the codes/SMS etc. ?
The attacker would need to have assistance from someone who has the ability to update your mobile phone account with a new SIM card. This means the attacker can be in any location. Some mobile phone operators have employees based in other countries than where they operate.
